**Definition**  
A measure used to evaluate the efficiency or profitability of an investment, such as in Customer Relationship Management (CRM)  
software or Enterprise Resource Planning (ERP) systems. A software that helps organizations manage interactions with current and potential customers. Systems that integrate various business processes and functions  
into a single comprehensive system. A process used in software development that outlines the stages  
from initial planning to deployment and maintenance. A standardized modeling language used to visualize the design  
of a software system. The process of making a software application available for use in a  
live environment. The server-side part of a software application that manages data and  
business logic. The client-side part of a software application that interacts with the user. A structured set of data held in a computer, typically managed by a  
database management system (DBMS). Application Programming Interfaces (APIs) that adhere to the principles of  
Representational State Transfer (REST) for communication between systems. Simple Object Access Protocol (SOAP) services that use XML-based  
messaging for communication between applications over the internet. Methods such as message queues and publish/subscribe systems used to  
integrate components that handle long-running tasks or high volumes of  
requests, improving system responsiveness by decoupling components. HyperText Transfer Protocol Secure, a protocol for secure communication  
over a computer network. An open standard for access delegation commonly used to grant websites  
or applications limited access to user information without exposing passwords. JSON Web Token, a compact, URL-safe means of representing claims to be transferred between two parties. Contracts between service providers and customers that define the level  
of service expected from the service provider. Digital Imaging and Communications in Medicine, a standard for handling,  
storing, and transmitting information in medical imaging. Logical Observation Identifiers Names and Codes, a universal standard for  
identifying medical laboratory observations. Laboratory information system, a software that manages data and  
workflows in a laboratory setting. A collection of remote servers and software networks that provide various  
computing services over the internet. An open-source framework that allows for the distributed processing of  
large data sets across clusters of computers. An open-source distributed computing system used for big data  
processing and analytics. A search engine based on the Lucene library, used for full-text search,  
analytics, and more. The live environment where software applications are run and used by end-users. A measure of how often a model correctly predicts the actual value. The proportion of positive identifications that are actually correct. The proportion of actual positives that are correctly identified by a model. A measure that combines precision and recall, providing a single metric for model performance. Receiver Operating Characteristic curves, graphical plots that illustrate the diagnostic ability of a binary classifier system. A table used to describe the performance of a classification model by comparing actual versus predicted values. The visual displays of key metrics and data points, often used for monitoring and analysis. The groups of transactions or data processed together at one time. The point at which a new system or software application is put into production and becomes operational.
