Study Notes
Components of Database System
- Database: An organized collection of structured information stored electronically, typically controlled by a Database Management System (DBMS).
- DBMS: Intermediary between the database and users/programs, enabling data retrieval, updating, and management. Facilitates administrative operations like performance monitoring, backup, and recovery.
- Database Application: Computer programs that act as intermediaries, allowing users to interact with the DBMS through database query languages.
-
Users:
- Naive users use predefined interfaces (e.g., web/mobile apps).
- Application programmers develop application software.
- Sophisticated users interact directly with the DBMS using query language without programming.
Types of Data
- Structured Data: Follows predefined formats and schemas, easily stored and queried.
- Unstructured Data: Exists in its raw state without a predefined format, can vary greatly in type and size.
- Semi-structured Data: Contains data items with different attributes and semantic tags, lacks a strict schema.
Example of Structured Data
- Sample entry for a database:
- ID: 1
- Name: Justin York
- Age: 27
- Gender: Male
- Address: Makati, Philippines
- Contact: +639358491124
- Email: [email protected]
Database System Architecture
- Involves the design and construction of databases, focusing on their operation and integration within existing structures.
- Centralized Database System: A database located at a single site, emphasizing simplicity in management and access.
Types of Database Management System
- Different DBMS types may exist, categorized by their architecture and functionality, though specifics on types are not detailed in the text.
