Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Connect to the database | 1.1 Identify site data needs from the technical requirements 1.2 Connect to the database from a web application using a web development language |
2. Retrieve data from database and display on web pages | 2.1 Retrieve data using structured query language (SQL) 2.2 Display the data in the most appropriate control 2.3 Format the data so that it is displayed in the most effective way |
3. Update the database data from user input | 3.1 Update the existing data stored in the database with user-supplied input 3.2 Insert the data in the database with user-supplied input 3.3 Delete the data stored in the database 3.4 Validate the data and check for errors |
Evidence of Performance
