Elements and Performance Criteria

1. Analyse the requirements for the database
   • Determine the information that the database is required to hold
   • Develop a written requirement report for the functionality of the database
   • Complete the documentation, and submit it to the appropriate person for approval
2. Use data modelling to design the database to suit requirements
   • Design an entity-relationship (ER) diagram to model the relationships between the entities and the attributes that the database will hold
   • Develop primary and foreign keys to link the entities
   • Develop a data dictionary
   • Complete the documentation, and submit it to the appropriate person for approval
3. Create a database on a web or database server
   • Use the appropriate language on a web or database server to create one or more databases
   • Use the appropriate language on a web or database server to create tables
   • Populate the database fields
4. Test the database and debug
   • Test the database on the web or database server
   • Ensure that the information represented matches the requirements

Performance Evidence

Evidence of the ability to:

research client requirements for a database solution

design a database that meets client requirements

create a database on a web hosting service or server to meet client requirements by a due date

test and debug the database.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

Knowledge Evidence

To complete the unit requirements safely and effectively, the individual must:

outline the principles of open platforms, including browsers and databases

list the processes associated with the creation of entities, attributes, and in populating fields, using both software solutions and script- based input

describe data-modelling techniques to design a database

outline the steps in database design, modelling and implementation

describe the internet operation related to web servers and clients

identify the naming conventions appropriate to database design

identify security restrictions on servers, incorporating some theoretical concepts

describe best practice communication, and accessibility, for audiences with special needs.
