Study Notes
Database Management System
- A Database Management System (DBMS) is essential for creating, maintaining, and controlling user databases.
Disadvantages of File Processing
- File processing systems face challenges such as data dependency and data duplication issues.
- Additional concerns in file processing include data integrity problems.
Database Approach
- The implementation of a Database Approach necessitates a Database Management System (DBMS).
Relationships in Databases
- One customer can place multiple orders, but each order originates from a single customer.
- Each order comprises several order lines, with each line relating to a specific order.
- Products can appear in various order lines, while each order line directly corresponds to one product.
- A many-to-many relationship occurs between multiple products and orders.
Systems Development Life Cycle (SDLC)
- The primary aim of the Systems Development Life Cycle is to ensure a comprehensive understanding of the system's needs.
- Key steps within the SDLC include Planning, Analysis, Logical Design, Physical Design, Implementation, and Maintenance.
- The Deliverable during the Planning phase of the SDLC is a request for resources.
Database Activity in SDLC
- During the SDLC, database activities encompass enterprise modeling and the formulation of early conceptual data models.
Final Phase of SDLC
- The concluding phase of the SDLC focuses on developing technology and establishing organizational structures.
Database Programs and Maintenance
- Database processing programs are integral components of a database system.
- Key purposes of SDLC also include programming, testing, training, installation, and conducting maintenance.
- Database maintenance encompasses continuous activities such as monitoring, repair, and optimization.
Three-Schema Architecture
- The three-schema architecture is comprised of an external schema, internal schema, and conceptual schema.
Prototyping and Client/Server Architecture
- Prototyping serves as a methodology within database design and development.
- Enterprise Database Applications often adopt a three-tiered client/server database architecture.
