INFORMATICS Unit 3 Outcome 1 SCHOOL-ASSESSED COURSEWORK Performance Descriptors Task 1 Very Low Low Medium High Very High Unit 3 Outcome 1 Design a solution, develop it using a relational database management system, and diagrammatically represent how users interact with an online solution when supplying data for a transaction Very few solution requirements are represented in the design indicating limited interpretation of the analysis. Some solution requirements are represented in the design indicating an understanding of some key aspects of the analysis Key solution requirements are represented in the design indicating a sound interpretation of the analysis Most key solution requirements are represented in the design indicating a clear interpretation of the analysis All key solution requirements are represented in the design indicating a thorough interpretation of the analysis Very limited or inappropriate design tools are selected and limited techniques applied to outline the data types, structures and how the solution will function. A range of errors of fact or logic affect the quality of the designs. Few appropriate design tools are selected. Some correct techniques are used to describe data types, structures and how the solution will function. Some errors of fact or logic affect the quality of the designs. Some appropriate design tools are selected. Mainly correct techniques are applied to describe data types, structures and how the solution will function. Some errors affect the quality of the designs. Appropriate design tools are selected. Correct techniques are applied to describe the data types, structures and how the solution will function. Minor errors exist. All selected design tools are appropriate. Correct techniques are precisely applied to accurately describe data types and structures and how the solution will function. The designs are error free. Limited checking of the reasonableness of data. Limited validation techniques used to check the reasonableness of data. Some validation techniques adequately check the reasonableness of data. Most validation techniques efficiently and effectively check the reasonableness of data. All validation techniques efficiently and effectively check the reasonableness of data.
Unit 3 Outcome 1 Design a solution, develop it using a relational database management system, and diagrammatically represent how users interact with an online solution when supplying data for a transaction Limited interactions between the user and online solution represented in a user flow diagram. Brief annotations outline relationships little reference to a data protection method. Some interactions between the user and online solution correctly represented in the user flow diagram. Some relevant annotations including reference to a data protection method. Interactions between the user and online solution are generally correctly represented in the user flow diagram. Most annotations adequately describe relationships and an appropriate data protection method. All interactions between the user and online solution correctly represented in the user flow diagram. All annotations adequately describe relationships and appropriate data protection methods. All interactions between the user and online solution have been correctly and comprehensively represented in the user flow diagram. All annotations fully and accurately describe the transaction requirements and appropriate data protection methods. Very few design features of the relevant user interface are included. Some design features of the relevant user interface are represented. Most design features of the relevant user interface are accurately represented. All key design features of the relevant user interface are accurately represented. All design features of the relevant user interface are accurately and clearly represented.
