    Study Notes

    Database Fundamentals

    • A database is an organized collection of data that enables efficient access, management, and updates of data and information.
    • Databases interact with data by storing it in structured formats, facilitating the retrieval and manipulation of information.

    Characteristics of Valuable Information

    • Valuable information should be accurate, relevant, timely, and accessible.
    • Quality information supports effective decision-making and enhances productivity.

    File Maintenance Techniques

    • Adding records: Involves inserting new data entries into a database.
    • Modifying records: Refers to updating existing data to ensure it reflects current information.
    • Deleting records: Entails removing outdated or irrelevant data from the database.

    Data Validation Techniques

    • Validation techniques ensure data integrity and accuracy before it is entered into the database.
    • Common methods include checks for data type, format, range, and consistency.

    Key Terminology

    • Character: The smallest unit of data, representing a single letter, number, or symbol.
    • Field: A single category of data within a record, such as a name or date.
    • Record: A collection of related fields that represent a single entity within a database.
    • File: A collection of related records.

    File Processing vs Database Approach

    • File processing approach handles data in separate files, often leading to redundancy and inconsistency.
    • Database approach centralizes data in one location, promoting data integrity and reducing duplication.

    Functions of Database Management Systems (DBMS)

    • Common DBMS functions include data storage, retrieval, updating, and administration of data.
    • DBMS supports data security, multi-user access, and efficient data processing.

    Types of Databases

    • Relational databases store data in tables and are characterized by predefined relationships among data.
    • Object-oriented databases integrate object-oriented programming with database technology, supporting complex data types.
    • Multidimensional databases allow for data to be viewed from multiple perspectives, often used in data warehousing.

    Accessing Web Databases

    • Web databases can be accessed through web applications and services, enabling users to retrieve and manipulate data remotely.

    Role of Database Analysts and Administrators

    • Database analysts design and optimize databases to ensure efficient data management.
    • Database administrators maintain database performance, manage user access, and ensure data security.
