Study Notes
General Aspects of System Design
- The purpose and scope of a system are established by identifying its objectives and aligning them with organizational objectives.
- User requirements are crucial for understanding user needs and expectations.
- Feasibility studies evaluate the technical, economic, and operational viability of the system.
- System architecture defines the structure and components of the system, including client-server or peer-to-peer architectures.
- Data design involves creating databases and data storage mechanisms, defining relationships, constraints, and normalization for data integrity.
- Input and output design specifies how data is entered and output formats for presenting information, considering user interface usability.
- Processing logic develops algorithms and processes to handle data transformations and business rules, aiming for efficiency.
Documentation of the Latest System
- The system overview includes a clear explanation of the purpose and objectives of the system, outlining the problems it solves or improvements it brings.
- System architecture documentation includes diagrams showing the overall architecture, depicting relationships between components, modules, and layers.
- Component descriptions provide detailed explanations of each system component, highlighting their roles and interactions.
- The code number system documents the structure and format of codes used for identification, specifying rules for code assignment.
- Logical file subsystem documentation includes diagrams illustrating logical relationships between data entities and detailed descriptions of file structures, attributes, and relationships.
- Security and audit documentation outlines security policies, measures implemented to safeguard data and resources, and details audit trail mechanisms.
- Computer scheduling of work documentation describes scheduling policies, algorithms used for task prioritization, resource allocation, and load balancing.
- Cost and savings analysis provides a detailed breakdown of initial and ongoing costs associated with the system and projections of potential cost savings and efficiency gains.
