Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA 

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1.2 Review function of required DAL in multi-layer application model

1.3 Determine data-access application programming interface (API) according to task requirements

2. Establish connection with data source

2.1 Create and manage connection strings according to task requirements

2.2 Connect data source using different data providers according to organisational procedures

2.3 Handle connection exceptions using code

3. Execute commands and return results from data source

3.1 Query data from data source according to task requirements

3.2 Retrieve and manage results sets from data source

3.3 Manage exceptions when retrieving data

4. Modify and manage data in data source

4.1 Insert, update and delete data according to task requirements

4.2 Confirm data integrity

Performance Evidence

The candidate must demonstrate the ability to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, including evidence of the ability to:

  • create at least one data access driven application.

In the course of the above, the candidate must:

  • select and code data-access layer of multi-layer applications
  • retrieve and update data from at least one data source
  • document all changes including code and database connectivity.

Knowledge Evidence

The candidate must be able to demonstrate knowledge to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, including knowledge of:

  • features of object-oriented design and multi-layer applications
  • relational database management systems, functions and tools
  • data-access-layer (DAL) and its functions
  • a range of application programming interfaces (API)
  • different data providers and vendors
  • object-oriented programming expressions and formulas at an intermediate level
  • principles of Structured Query Language (SQL)
  • organisational guidelines and procedures applicable in assisting the development of data-driven applications.

Assessment Conditions

Skills in this unit must be demonstrated in a workplace or simulated environment where the conditions are typical of those in a working environment in this industry.

This includes access to:

  • integrated development environment (IDE)
  • data access application program interfaces (APIs)
  • required data-access layer (DAL)
  • database management system software and files
  • coding standards
  • specific tools and licences, as required for particular data-access API
  • different types of data-access methods including data retrieval and storage, back-end coding and disconnected data management.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
