, 2022; Manzoor et al. , 2020; Baggia et al. , 2018). One tool that could introduce students to cloud computing concepts for database and application development is Oracle APEX. Oracle APEX is the world's most popular enterprise low-code application platform that enables students to build scalable, secure enterprise applications that can be deployed anywhere -in the cloud or on-premises. (Oracle,2023; Baggia et al. , 2019). In this work, laboratory exercises and a short user manual of ORACLE APEX in Greek were developed and included in the teaching of the course "Databases" of the 5th semester of the CITE Department of IHU. At the end of the course, a questionnaire was distributed to the students in order to record their opinion on their experience of using APEX and to evaluate the teaching method.
Oracle Application Express (APEX) Oracle today makes its popular APEX low-code development platform available, as a managed cloud service that developers can use to build data-driven business applications quickly and easily. It is already used by 500,000 developers through a browser-friendly environment to create modern web and mobile applications. Initially the APEX platform was only available as part of the Oracle database, but after many improvements today APEX Application Development is available as a standalone service and works with a variety of web applications  (Geller & Spendolini, 2017). A recent study by  (Pique Solutions, 2019)  showed that developers could build enterprise applications almost 40 times faster with Oracle APEX service without having to learn complex programming technologies.
It provides integration of the application with the database, reducing the communication time between the application and the database by 10 times, resulting in much faster response times. In addition, application developers can take full advantage of the power and simplicity of SQL in building complex queries. One of the advantages of APEX is that it does not require client software, it does not require user maintenance, it requires minimal code, it allows end users to interact with their data through tools such as interactive reporting, interactive grid, different types of charts, the analysis maps and functions  (Riaz, 2018). It also enables developers to embed SQL, PL/SQL, HTML, JavaScript and CSS to enhance their application. With a web browser with the help of Oracle Apex end users are able to create but not limited to: Model database objects, Load/unload data, Create REST interfaces on that data, Create applications on those database objects, Implementation and development of applications.
Quickly create reports, forms, charts, calendars, etc. Additionally, one of the main advantages is the high degree of independence and security of the platform from the client's side  (Geller & Spendolini, 2017). Figure  1  shows the basic options provided to the user after creating the necessary Workspace. The methodology used to easily introduce students to the Oracle APEX environment is described in Figure  2. The first step was to research and investigate new tools for the design of databases and the implementation of web applications. This search revealed the difference of the Oracle APEX environment for low-code programming and rapid web application development, and as a result, this environment was chosen for applications in the laboratory part of the database course. First of all, a short Oracle APEX User's Guide was developed in Greek language, describing the basic features and tools provided by this platform, so that students can use it and solve problems related to the use of these tools.
Targeted tools provided by the Oracle APEX environment were chosen in order to enable students to put into practice the knowledge they have learned until the 5th semester of their studies. Two laboratory exercises were then designed to take students step by step through the creation of a database and tables, either using SQL statements or by importing a data file and creating the corresponding forms, reports and statistics. In order to integrate these exercises into the laboratory part of the course, the teaching program of the laboratory part was modified. Finally, the students were asked to answer a questionnaire designed to record their opinions, attitudes and experiences in using this new environment. Finally, the statistics of this small survey were recorded. The number of students who participated in this process was 40.
Introduction to Oracle Apex Quick Guide in Greek The development of a short guide in Greek to introduce students to the Oracle Apex environment is a necessary process so that students will have a reference and help book for the development of their own DBs and applications. There is also a lot of material available on the Oracle Apex environment in the form of videos, tutorials, tips, slides and exercises. However, this material is mainly available in English. As part of the Erasmus+ BeeAPEX program, in which the team behind this work is also a participant, a unique effort is underway to develop Oracle Apex training material in various languages other than English. The Oracle Apex Quick Guide in Greek, developed for the students of the BYT Department of DIPAE, consists of the following sections, which are presented in Table  1.
Lab exercises for undergraduate students The objective of the lab exercises is to introduce and familiarize the students with the ORACLE APEX environment by developing a database and tables using SQL commands for a case study concerning an application that manages data about workers, departments and projects that the workers work on. In order to carry out this exercise, there are specific steps that the students must follow in order to successfully complete the exercise. In the first steps of logging into the ORACLE APEX environment for the first time at https://apex. oracle. com, the students have to apply for a new workspace using their academic email address. In the next steps, using the SQL Workshop option, they can create tables in the ORACLE database space in several ways. In the first lab exercises, students will use the Object Browser and SQL commands.
They will learn how to create tables either by using SQL scripts or by using the New Table Form, defining the fields of the tables, the data types, the primary keys and the foreign keys. In order to practice with the new environment and SQL commands, they inserted new records into the tables or updated inserted data using SQL commands. A procedure that excited the students was their first application development using the New Page command of ORACLE APEX, where they could select many options offered by the APEX environment, such as forms, reports, statistics. Finally, using low code in their application development, the students run their application and immediately see their work in a web-based application running on the cloud of ORACLE APEX. Screenshots of one of the exercises used by the students for their first application with APEX are shown in Figure  3.
Questionnaire Design In order to get feedback from the students about their opinions, attitudes and positions regarding their experiences in the ORACLE APEX environment, a short questionnaire was designed, consisting of the questions in Table  2. This questionnaire was given to the students to complete at the end of the 13 laboratory sessions of the semester, after having dealt with two other RDBMS, ACCESS and MS SQLSERVER, in addition to ORACLE APEX. Ten of the questions are closed, Likert-type questions and one of them is an open-ended question where the students were asked to add their comments (question 7) for the improvement of the database laboratory exercises. Introduction to Oracle APEX Short Guide in Greek (E5) and the selected topics of the Short Guide (E6), all students rated them as helpful for the learning process.
This paper presents the methodology used for the integration of ORACLE APEX in the laboratory exercises of the Database course of the Department of Computer Information and Telecommunications Engineering of the International Hellenic University. According to the answers of the students to the questionnaires given to them at the end of the semester, the acceptance of the ORACLE APEX environment was global. The objective of using the tools provided by this platform was fully achieved. The students learned to easily create highly complex web applications with low coding through the ORACLE APEX environment and this fact seemed to excite them and they will continue to use these tools to develop their own applications in the future. Furthermore, when comparing the different RDBMS taught during the semester, such as MS ACCESS and MS SQL SERVER to ORACLE APEX, the students felt that the environment and capabilities provided by ORACLE APEX were better.
A. Angeioplastis, A. Tsimpiris, D. Varsamis, A. Baggia, R. Leskovar: Data Analysis of Student's Performance on "Database" Course with ORACLE APEX Statistics 27 The research of  [Arora & Singh, 2016]  attempted to categorize the factors found to affect the academic performance of students into the following categories: Psychological, Social, Financial, Environment. The purpose of this work is initially to study and analyze the data obtained by the students regarding their performance in the "Database" course. The presentation of success rates of the students, the distribution of their grades and the exact time of success of the course Considering that performance represents the understanding and consolidation of course content, we realize how important such analyzes are. Additionally, this study investigates the correlations between factors that influence academic performance such as the students' school of origin, gender and student origin.
Dataset In this work, the research population consists of all the undergraduate students of the department from its operation in 2003 until 2021 covering a 19-years long period. This dataset is consisted of 6600 records and 30 features. We focused on 7 features that represent demographic characteristics and the grade of the students (See Table1) Due to the difficulty of recording and the inadequacy of all the information about the students, the work was chosen to focus the research on the student performance in the years 2003-2021. The data for this work extracted from the online student portal of the university's electronic secretariat. One excel file was about the students of the department with information in 67 columns and another excel file had information about the "Database" course of Computer, Informatics and Telecommunications Engineering Department (CITE) of International Hellenic University (IHU).
Oracle Application Express (APEX) Oracle is a popular platform and cloud service where users can develop complex applications with simple code. It is used as a web and mobile application development tool by thousands of users. The APEX platform is constantly improving in terms of the services it offers enabling developers to develop applications faster than other competing solutions  (Geller & Spendolini, 2017) , Pique Solutions, 2019. Users enjoy all the conveniences of client/server applications A. Angeioplastis, A. Tsimpiris, D. Varsamis, A. Baggia, R. Leskovar: Data Analysis of Student's Performance on "Database" Course with ORACLE APEX  Statistics 29  with minimal code without the stress and problems of maintaining their application. The tools provided include interactive reports, interactive grid, forms, calendars, different types of graphs, maps, and analysis functions  (Riaz, 2018).
Methodology The methodology followed for the implementation of this work is presented in Figure  2  and concerns the extraction of data from the central database of the IHU for the years 2003-2021. The process of data extraction presented the difficulty that we had to extract data by year due to the different entries in the tables of the central database. The data was then cleaned and consolidated, a process that required attention because the fields used over the years often varied according to updates to the central scores registration application. Creating a database in the ORACLE APEX environment helped to consolidate all the individual tables and avoid redundancy in the data. ORACLE APEX tools then helped in creating graphs and descriptive statistical analysis of the results. The progress of the successful candidates, the distribution of grades, averages and correlations between grades and other parameters of the students are presented through appropriate diagrams.
Results The results of the descriptive statistical analysis performed with the help of ORACLE APEX are presented in the following graphs. Figure  4  (grades) shows the distribution of grades which follows the normal distribution with most of the students having achieved a grade 5 in the exam (about 1200 students) while about 100 students achieved a grade equal to 10. Figure  4  (Gender) shows the distribution of males -females where females who attended the course Databases constitute 25% of the total. Also Figure  4  (School type) shows that the percentage of students who participated in the course exams are mainly from General High School, if 20% are from vocational high schools, a percentage close to 5% are from transfer students and a small percentage of 1% are from placement exams. An interesting information is drawn from the Figure  4  (Semester) graph showing that 35% of the students have passed the course in Semester 3 which is the semester the course was taught until 2021.
The diagram (Figure  8 ) shows the distribution of students by semester who decided to take the course of "Database". The vast majority of students have taken the exam in semester 3, 4 and 5 but disappointingly there are very few students who have taken the exam in semesters above semester 14 (n-years+2years) which is the limit of the course. Figure  9  shows that 34% of the students take the September exam while 64% prefer to take the exam in the winter semester when the course is taught.
Conclusions In this paper, descriptive statistics related to student performance in the course "Database" were studied using ORACLE APEX Statistics tools. The information obtained after applying the descriptive statistics is useful for the instructor and the students. Data were presented on the mean scores between males and females in which no statistically significant difference was shown despite the fact that female students constitute 30% of the total sample studied. The distribution of scores over a period of 19 years follows the normal distribution which is the desired distribution, with no major changes from this distribution. As an extension of this work, more statistical functions from the ORACLE APEX environment will be used to extract useful information for prediction and categorization of the data.
These include  (AMFG, 2019) : the industrial internet of things, big data, cloud computing, additive manufacturing (AM), advanced robotics, augmented and virtual reality (AR/VR), artificial intelligence, and robotics. Big data refers to large and complex sets of data that cannot be collected and stored in traditional databases and cannot be analyzed using traditional methods, techniques, and tools. The characteristics of big data are known as the "7 V  's": velocity, volume, variety, veracity, variability, visualization, and value (Cvetkoska, 2022, p. 26). Big data analytics is able to analyze and extract useful insights from vast quantities and varieties of data. Big data analytics are improving and will be more heavily used in Industry 4. 0  (Zhang, 2020). These large volumes of data will be analyzed in correlation with each other in order to identify phases with redundant processes that may be streamlined.
The concept of blockchain technology within energy companies In the modern business of energy companies, blockchain technology is gaining particular importance. Blockchain serves as a database that is developed on a peerto-peer network. Its main characteristics are that it is decentralized, distributed, replicated and completely transparent. Kasireddy (2017)  defined blockchain as a technology with a shared state of all the transactions, secured with asymmetric cryptography. Access to the network is allowed to any device connected to the internet. All of the devices, nodes, that are part of the network have copies of all transactions that have ever happened. Nodes continually communicate with each other and synchronize recorded transactions. Interaction between participants is done through transactions.
Usually for BI OLAP cubes are used. OLAP cubes are computer-based technique of analyzing data to look for insights. The term cube here refers to a multidimensional dataset, which is also sometimes called a hypercube if the number of dimensions is greater than three. The app (fig. 2 ) consists of three large parts: frontend application, backend application, Cube JS instance. Frontend part will be implemented with React JS framework because of simple connecting to Cube JS instance. In this app user can request some chart that help him perform BI analysis in toursim area, moreover the system is able to investigate whether the request has some similar questions from previous users. Cube JS has API to create appropriate result set of data to create charts in React web app. Source of the data for chart is MongoDB.
Compared to other forms of promotion, public relations are primarily informative in nature, as they are based on journalistic news, events or news with the intention of increasing recognition, credibility, acceptance and reputation of women in their own business. The purpose of public relations is to create good communication between entrepreneurs and other participants in the business environment in order to best influence knowledge, ideas, attitudes and behaviour in terms of products, services or brands. Direct marketing enables "one-to-one" communication with the target audience through one or more media, with every transaction information entered into a database. Based on this information, consumers are identified, contacted by creating personalized messages, predicting future sales, but also predicting new trends in consumer behaviour, which will contribute to the development and increased placement of products.
On the other hand, there has been an increase in the dropout rate in follow-up master's study programs, especially after the year 2014  (Sagenmuller, 2018). While the overall dropout rate is less than one third and thus significantly lower than that in bachelor's study programs, this trend should be taken seriously. This is also the case at the Prague University of Economics and Business (Prague University of Economics and Business -PUEB). The Faculty of Informatics and Statistics is one of the faculties with the highest dropout rate at the PUEB. The dropout rate is significantly higher in bachelor's study programs  (Berka, Marek, 2022). This article, which is part of deeper study result analyses performed at the FIS, shows the dropout rate in master's study programs. We used the database of PUEB students and applicants and their study results as the primary source of data for our research.
In 1959 Goetz referring IBM and McKinsey-Harvard Business Review games, pointed out the costs associated with the duration of the game. Systematic review of papers published in databases proved that there was limited evidence, that playing business games may change leadership behaviors or skills  (Lopes et al, 2013). Some results indicate that participation in the game, not only does not boost entrepreneurial intentions, but students may feel less prepared to start their own businesses  (Pérez-Pérez et al. , 2021). Henriksen & Børgesen (2016)  referring to the impact of simulation on leadership noted, among other things, that it can be positive, under the condition that participants are allowed to engage in emergent non-formal and informal discussion. The ultimate perception of the game by the participants and its effectiveness, is influenced by a set of variables -linked in general to the participant (like gender, nationality, cognitive style, previous academic performance, previous contact with another simulated environment, etc.
Introduction The first phase of the design of the regional development plan for Gorenjska region is traditionally supported by the initial brainstorming sessions with expert groups  (Škraba & Filipič 2009). Since new technologies have emerged, it is our intention to examine the possibility to augment brainstorming sessions with AI tools such as ChatGPT  (Radford, 2019) , Ayoa (Ayoa 2023) and python NLP libraries. Here we consider the generation of ideas as well as ranking. Our case study will target human resources development in Gorenjska region. The ChatGPT technology has been successfully applied for the purpose of brainstorming in a bid to get better insight when faced with nebulous and diagnostically challenging cases  (Kung et al. , 2022). This is quite remarkable since medicine  (Jeblick et al.
The possession of development and coding skills is traditionally associated with concrete IT professions such as front-end developer, back-end developer and web developer. Because of the advancement of the digital economy, however, these skills are increasingly needed and used in a wide range of other professions in which case they are complementary, not primary, for the performance of one's job. The project's objective is to contribute to the digital transformation of six higher education institutions through the development of the digital capabilities of their educators and students, in particular through the development of blended learning resources and the development of novel teaching and collaborative capacities. Firstly, the digital capabilities of teaching and research staff is to be enhanced through the organizing of training on and expertise-exchange in the areas of digital course creation, lowcode programming, and front-end and back-end development of applications and databases.
Requirements Essence definition: What the software system must do to address the opportunity and satisfy the stakeholders. It is necessary to provide high quality education material on low-code programming (in Oracle Application Express -APEX), which include textbook, software, data and videos. Textbook must provide student of any discipline clear guides to: • get started with APEX low-code environments, prepare a database, navigate through APEX, exchange data, generate web and mobile application, manage reports, forms and menus, facilitate teamwork in APEX, find the benefit of sample and starter applications and to manage packaged and multilingual web applications in APEX • develop own application inspired by twelve cases from real life of different sectors of economy. Each case must include: business view, problem definition, use case textual, semi-structured and graphical presentation, data model development process (narrative description, logical, relational, physical) via forward and possibly reverse engineering and finally interface design.
Software system Essence definition: A system made up of software, hardware, and data that provides its primary value by the execution of the software. Twelve business cases included as textbook chapters result in low-code web applications. Development environment is Oracle APEX as one of the most viable and capable tools. The constraint is that application can't run on other databases, however the argument of always free availability to anyone, resolves the risk of locking to one vendor. Primary value of each application is that principles of data driven web application development in different contexts can be transferred thus enabling students to reuse and enhance the competences in the real business environment. Applications are focused on: internet news for employees, catalogue of local plants, user authorization and management, small innovation system, business process management, exchange of plants and seeds, book review management system, calculation of bill of material, nutrition and diet management, office hours scheduling, telecommunication services billing and car rental.
