ICADBS401A
Identify physical database requirements

This unit describes the performance outcomes, skills and knowledge required to identify the physical requirements of a database, including a data dictionary and security and design specifications.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.

Application

This unit applies to database administrators who are required to plan the building of a database.

It is necessary before designing a database to take into consideration a range of requirements, including current IT architecture and client requirements, the organisation’s IT standards especially related to security, and the outcomes of the business-analysis process.

Prerequisites

Not applicable.

Elements and Performance Criteria

1. Identify database scope	1.1 Review requirements of the user and current system architecture 1.2 Determine database size from requirements and technical specifications 1.3 Document database and scope of project 1.4 Evaluate several database-management systems against requirements and make appropriate selection
2. Identify database requirements	2.1 Review technical specifications for the database 2.2 Identify database tables and relationships 2.3 Identify database data dictionary, table attributes and keys 2.4 Develop database reports based on acceptance criteria and requirements
3. Identify security requirements	3.1 Review system-security plan 3.2 Clarify and confirm chosen database-management system and user security required for the database to ensure database security is aligned to security-system plan 3.3 Identify, evaluate and record database performance, recovery and audit trail needs
4. Seek client feedback and approval	4.1 Present database scope, technical requirements and security documentation to user for feedback 4.2 Review user feedback and adjust database documentation as required 4.3 Present database documentation to user for final approval

Evidence Required

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: analyse client requirements identify technical considerations affecting the physical design of a database produce a security plan for the database.
Context of and specific resources for assessment	Assessment must ensure access to: user-business requirements technical documentation defining architecture platform and operating system specifications database-supplier technical specifications and manuals data samples database package 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: review of the final database, specifying business rules, agreed budget and timeframe evaluation of documentation, detailing: database directories calculation of space requirements for tables additional space requirements design of node groups security plan.
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.

Range Statement

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. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Requirements may relate to:	business network people in the organisation system.
User may include:	department within the organisation person within a department third party.
System architecture may include:	configuration: large memory model requests per second small memory model database software: DB2 Informix Ingres Microsoft Structured Query Language (MS SQL) server Mini SQL (mSQL) MySQL Oracle Sybase operating system: Novell NetWare multi-user ability Linux Mac Windows.
