Release 1

This version first released with ICT Information and Communications Technology Training Package Version 1.0.

Application

This unit describes the skills and knowledge required to establish client needs and technical requirements and to design a database that meets those requirements.

It applies to individuals employed as database administrators and designers who are required to design databases.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

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. Determine database requirements

1.1 Meet with the client, and conduct a user-needs analysis, to determine database functionality

1.2 Analyse the results of a user-needs analysis to identify technical requirements

1.3 Develop a conceptual model of the database

1.4 Submit the conceptual model to the client for review

1.5 Evaluate client feedback and make changes as required

2. Develop a logical data model

2.1 Identify the attributes and determine the data types

2.2 Undertake the normalisation of attributes

2.3 Develop an entity-relationship (ER) diagram in order to clarify the cardinality of relationships

2.4 Document attributes, normalised data, and the ER diagram

2.5 Forward documentation to the client for confirmation

3. Design the data structures

3.1 Confirm primary and foreign keys for tables

3.2 Review client business rules

3.3 Identify the referential integrity constraints

3.4 Establish database management system constraints and incorporate into database design

3.5 Develop the validation rules for data

3.6 Design indexes and develop the data dictionary

3.7 Document the database design

4. Design queries, screens and reports

4.1 Design the 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 the physical design with the conceptual model, or user-needs analysis

4.5 Incorporate changes as required

5. Design access and security systems

5.1 Review the business security plan as a basis for commencing the access and security design

5.2 Design the password and access system for the database

5.3 Identify multiple-user requirements

5.4 Develop client access profiles using the client business model

6. Confirm the database design

6.1 Identify the database backup and recovery requirements

6.2 Develop and document the database backup and restore procedures

6.3 Submit the database, and documentation, to the client for final approval

Foundation Skills

This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.

Skill 

Performance Criteria 

Description 

Reading

1.2, 1.5, 2.1, 3.2, 3.3, 4.4, 5.1, 6.1

  • Interprets textual information obtained from a range of sources and determines how content may be applied to requirements

Writing

1.3, 2.3, 2.4, 3.7, 6.2, 6.3

  • Develops content in a manner that supports the purposes and format of the requirements using appropriate structure, layout and specialised technical and programming language

Oral Communication

1.1, 1.4, 1.5, 2.5, 3.2, 5.1, 6.3

  • Uses listening, questioning and summarising techniques to identify needs, and uses specific and clear language when engaging with others

Numeracy

3.4, 4.1, 4.3, 4.4

  • Makes measurements and performs calculations for work layout, determine field lengths and table size and estimate database size

Get the work done

All

  • Uses a combination of formal, logical planning processes and an increasingly intuitive understanding of context to identify relevant information and risks, identify and evaluate alternative strategies and resources
  • Uses systematic, analytical processes in complex, non-routine situations, setting goals, gathering relevant information, and identifying and evaluating options against the agreed criteria
  • Understands the key principles and concepts underpinning the design, and operation, of digital systems and tools

Modification History

Release 

Comments 

Release 1

This version first released with ICT Information and Communications Technology Training Package Version 1.0.

Performance Evidence

Evidence of the ability to:

  • identify and confirm client requirements for a database application
  • design database elements including:
  • structure
  • indexes
  • queries
  • screens
  • reports
  • design secure access to the database
  • confirm final database design with the client.

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:

  • explain the process of data analysis, particularly in determining data types and data structures, query and report design
  • describe the data modelling related to developing the conceptual data model
  • explain how data redundancy is identified
  • describe database management system (DBMS) fundamentals, particularly during the design phase
  • explain encryption and authentication as these apply to database security features
  • outline the functions and features of data types, and data structures
  • describe the functions, and features, of databases
  • describe logical design concepts, particularly those related to designing data structures, queries screens and reports
  • outline the object model design concepts, particularly those related to designing data structures, queries, screens and reports
  • explain the term ‘scalability’ as it applies to databases.

Assessment Conditions

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the database field of work, and include access to:

  • equipment and materials
  • current industry accepted database software
  • network or other system for remote or multi-user access
  • business requirements
  • computer-aided software engineering (CASE) or diagramming software.

Assessors must satisfy NVR/AQTF assessor requirements.
