A methodology that creates and maintains information systems
Information Engineering
An IS planning methodology to gain a broad understanding of the IS needed by the organization
Top-down planning
What are the four steps to Top-down planning?
- Planning
- Analysis
- Design
- Implementation
What is the purpose of Information Systems Planning (ISP)?
To align IT with an org’s business strategies
What are the three steps to ISP?
- Identify strategic planning factors (SPF)
- Identify corporate planning objects (CPO)
- Develop an EDM
(ISP) What are the strategic planning factors?
- Org’s goals - what you want to accomplish
- Critical success factors - what must work for us to survive
- Problem areas - weaknesses
(ISP) What are the corporate planning objects?
- Org. units
- Org locations
- Business Functions - groups of business processes
- Entity types - things we try to model for the database
- IS - application programs
A process that breaks a system description into fine details
Functional decomposition
What is the full form of SDLC?
System Development Life Cycle
It is a detailed, well-planned development process
SDLC
It is time-consuming but comprehensive; long development cycle
SDLC
What is the full form of RAD?
Rapid Application Development
You repeat implementation and maintenance activities with new prototype versions
Prototyping
What are the two approaches to Database and IS development?
- System Development Life Cycle (SDLC)
- Prototyping
What approach is RAD under?
Prototyping
What are the parts of SDLC?
- Planning
- Analysis
- Logical Design
- Physical Design
- Implementation
- Maintenance
What is included in the Prototyping Database Methodology?
- Identify the problem
- Develop an initial prototype
- Implement and use the prototype
- Revise and enhance the prototype
- Convert to an operational system
