    Study Notes

    Database Fundamentals

    • Databases are organized collections of data that allow for efficient management, retrieval, and updating of information.
    • A database management system (DBMS) is software that facilitates the creation, manipulation, and administration of databases.

    Roles of DBMS

    • The DBMS serves as an interface between users and the database, allowing access to data while managing permissions and data integrity.
    • It provides tools for data input, querying, reporting, and data structure maintenance.

    Design Considerations

    • Some key considerations in database design include data integrity, normalization, indexing, and scalability.
    • Ensuring that the design accommodates future growth and changes is crucial to long-term sustainability.

    Storage Options for Databases

    • Small databases can be stored locally on personal computers or lightweight servers.
    • Large databases typically require hosting on dedicated servers or cloud platforms to manage the enhanced demands of performance and storage.

    Database System Defined

    • A database system is a combination of a database and the DBMS that interacts with it, enabling users to perform operations like data entry, storage, and retrieval.
    • The primary purpose of a database is to facilitate efficient data management and provide a structured way of organizing, storing, and retrieving data.
