    Types of Databases and Applications

    • Traditional Applications: Include numeric and textual databases.
    • Recent Applications: Encompass multimedia databases, Geographic Information Systems (GIS), biological and genome databases, data warehouses, mobile databases, and real-time or active databases.

    Recent Developments

    • Social Networks: Platforms such as Facebook, Twitter, and LinkedIn gather extensive data on user interactions, including posts, tweets, photos, and videos.
    • Search Engines: Google, Bing, and Yahoo create repositories of web pages to facilitate searching.

    Emerging Technologies

    • Big Data Storage: Strategies developed by non-database vendors to handle large data volumes generated online.
    • NoSQL Systems: Alternative database systems that support data storage beyond traditional SQL formats.
    • Cloud Storage: Large data concentrations housed in data centers utilizing extensive machine networks.

    Basic Definitions

    • Database: A structured collection of related data.
    • Data: Recorded facts with implicit meanings.
    • Mini-world: A specific segment of the real world represented in the database (e.g., student grades).
    • Database Management System (DBMS): Software that aids in the creation and maintenance of computerized databases.
    • Database System: Comprises the DBMS software along with the data.

    Impact of Databases

    • Business Sectors: Crucial for industries like banking, insurance, retail, transportation, healthcare, and manufacturing.

    DBMS Functionality

    • Database Definition: Outlines data types, structures, and constraints.
    • Initial Database Construction: Involves loading contents onto secondary storage.
    • Data Manipulation: Includes querying the database and generating reports, alongside content modifications like insertions and updates.
    • Concurrent Access: Allows multiple users and applications to process and share data while maintaining consistency.

    Application Interactions with Databases

    • Queries: Facilitate data access and generate specific results.
    • Transactions: Involve reading and updating data or creating new data.
    • Security Measures: Databases must restrict unauthorized access and adapt to evolving user requirements.

    Additional DBMS Features

    • Security: Incorporates protection against unauthorized access.
    • Active Processing: DBMS can perform internal data actions automatically.
    • Data Visualization: Tools for the presentation of stored data.
    • Maintenance: Involves long-term management of the database and accompanying programs.

    Example of a Database Model

    • Context: Represents a university setup.
    • Entities: Includes students, courses, course sections, departments, and instructors.
