Study Notes
Database Design and Implementation
- Requirements Analysis: identifies and documents the data needs of the new system.
- Conceptual Database Design: a visual representation of the database's structure is created using an Entity-Relationship Diagram (ERD).
- Normalization: Organizes data to minimize redundancy and ensure data integrity by decomposing large tables into smaller, related tables.
- Logical Database Design: Translates the conceptual model into a logical data model, often using a relational data model. This phase defines tables and establishes relationships based on entities and their attributes.
- Schema Refinement: Assesses the logical model for optimization, involving denormalization for performance or adding indexes to speed up queries.
- Physical Database Design: Implements the logical model in a specific database management system (DBMS) ensuring compatibility and functionality.
System Implementation and Maintenance
- System Implementation: Focuses on bringing the system into operation.
- Changeover Processes: Methods for transitioning from an existing system to a new one, minimizing disruption and ensuring smooth change.
- System Maintenance: Ongoing activities keeping the system operational, addressing issues and assessing the system's performance and relevance.
System Appraisal
- Performance Evaluation: Assesses the system's efficiency by measuring key metrics like response times, throughput, and resource utilization.
- Security Audits: Evaluates the system's security posture to identify potential vulnerabilities.
- Quality Assurance (QA): Ensures the development process adheres to quality standards and best practices through activities like code reviews and process audits.
- User Acceptance Testing (UAT): Validated the system's functionality and usability in a real-world environment.
- Regression Testing: Verifies that modifications or enhancements do not negatively affect existing features, ensuring system stability.
Data Processing Techniques
- Parallel Processing: Improves computational speed by allowing multiple processors or cores to execute tasks simultaneously.
- Machine Learning: Enables systems to learn patterns from data and make predictions or decisions without explicit programming.
Discussion Questions
- Explain the challenges of balancing thorough testing requirements with the pressure for expedited system implementation.
- How does user feedback contribute to the ongoing process of system maintenance and appraisal?
- Discuss the complexities and strategies involved in data migration during system changeover processes.
- What elements are important when presenting complex technical systems to diverse stakeholders?
- Explore the ways in which machine learning and artificial intelligence can enhance data processing techniques in modern systems.
