Study Notes

DBA Responsibilities

Monitor system load, performance, and storage to prevent failures.
Larger servers and databases may be necessary for optimal performance.

System Development Life Cycle (SDLC)

Maintenance involves identifying bugs or errors reported by users.
Users communicate issues to the IT department via email or phone.
Programmers fix the bugs and redeploy the system.
Deliverable: Operational Information System.

Life Cycle Models

Various models for system development include:
- Waterfall Model
- Spiral Model
- Iterative and Incremental Development
- Agile Model
- Prototyping Model
- Rapid Application Development (RAD)
- Joint Application Development (JAD)

Waterfall Model

Simple and easy to understand, with clear management protocols.
Each phase has specific deliverables and follows a rigid flow, with no overlaps.
Ideal for smaller projects with well-defined requirements.
Challenges include difficulty in making late changes, high risk and uncertainty, and not suitable for complex projects.

Spiral Model

Focuses on extensive risk analysis to mitigate risks effectively.
Particularly effective for large and critical projects requiring strong documentation.
Allows for additional functionalities to be added post-implementation.
Can be costly and success is highly dependent on thorough risk analysis.

Iterative and Incremental Development Model

Users can log in, manipulate data, and identify bugs.
Testers validate requirements through unit and system testing.
Deliverable includes Test Cases, Test Plans, and Test Results.

Implementation Phase

Project team prepares the production server, including hardware installation and database setup.
Some organizations may start with a pilot project before full launch.
Deliverable: Complete functioning system that goes live for end-users.

Maintenance Phase

Ongoing monitoring of the system is essential following successful deployment.
Adopts symbols and shapes to represent data flow, processing, and storage.
Traditional method relies on documentation and allows flexibility during iterations.

Structured Analysis

Utilizes defined phases: Planning, Analysis, Design, Implementation for SDLC.

Object-Oriented Analysis

Models systems as collections of objects that combine data and processes.
Objects can represent real entities like people and transactions.
Requires a more interactive approach with object-oriented diagrams.
Advantages include modular and reusable code, while disadvantages may involve complexity in interaction.

Agile/Adaptive Methods

Development is divided into iterations, enhancing functionality incrementally.
Each iteration is designed, built, and tested in a continuous cycle.
Emphasizes flexibility and efficiency, fostering team interaction.
Frequent deliverables allow for constant validation and risk reduction.
