    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.
