Description
This unit describes the performance outcomes, skills and knowledge required to establish client needs and technical requirements and to design a database that meets those requirements.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.
Notes
Elements and Performance Criteria
1. Determine database requirements
  • 1.1 Meet with client and conduct a user-needs analysis to determine database functionality
  • 1.2 Analyse results of user-needs analysis to identify technical requirements
  • 1.3 Develop a conceptual model of the database
  • 1.4 Submit conceptual model to client for review
  • 1.5 Evaluate client feedback and make changes as required
2. Develop logical data model
  • 2.1 Identify attributes and determine data types
  • 2.2 Undertake normalisation of attributes
  • 2.3 Develop entity relationship diagram to clarify cardinality of relationships
  • 2.4 Document attributes, normalised data and entity relationship diagram
  • 2.5 Forward documentation to client for confirmation
3. Design data structures
  • 3.1 Confirm primary and foreign keys for tables
  • 3.2 Review client business rules
  • 3.3 Identify referential integrity constraints
  • 3.4 Establish database-management system constraints and incorporate into database design
  • 3.5 Develop validation rules for data
  • 3.6 Design indexes and develop data dictionary
  • 3.7 Document the database design
4. Design queries, screens and reports
  • 4.1 Design user interface for database, including menus, input screens and outputs
  • 4.2 Design queries based on requirements
  • 4.3 Design output reports based on requirements
  • 4.4 Compare physical design with conceptual model or user-needs analysis
  • 4.5 Incorporate changes as required
5. Design access and security systems
  • 5.1 Review business security plan as basis for commencing access and security design
  • 5.2 Design password and access system for database
  • 5.3 Identify multiple-user requirements
  • 5.4 Develop client access profiles using client business model
6. Confirm database design
  • 6.1 Identify database backup and recovery requirements
  • 6.2 Develop and document the database backup and restore procedures
  • 6.3 Submit database and documentation to client for final approval
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the ability to:
design a well-structured database that represents the client's business reality and provides the user with a productive business tool.
Context of and specific resources for assessment
Assessment must ensure access to:
current industry-accepted database software, network or other system for remote or multi-user access
business requirements
CASE or diagramming software
appropriate learning and assessment support when required
modified equipment for people with special needs.
Method of assessment
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
observation of candidate liaising with client
verbal or written questioning to assess candidate’s knowledge of:
normalisation
indexing
security models
review of the final database and associated support documentation.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate.
Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.
Indigenous people and other people from a non-English speaking background may need additional support.
In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.
