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.
