    The Data, the People, and the Organisation

    • The value of a company lies in its people and its information assets. These assets are crucial for future success.

    Traditional File Systems

    • Older file systems often had problems with redundancy, inconsistency in data storage formats, and difficulties integrating data from different applications

    What is Data?

    • Data is a series of observations, measurements or facts
    • Computer systems operate on data
    • The 1984 Data Protection Act may be relevant

    What is a Database?

    • A database is a collection of related data with implicit meaning
    • It represents aspects of the real world (mini-world or Universe of Discourse)
    • Databases are designed for specific purposes and user groups with intended applications

    Database Systems

    • Database Management Systems (DBMSs) are software for defining, constructing, and manipulating databases in applications

    Requirements of a Database System

    • Efficiency: Needed for accessing and modifying large datasets
    • Resilience: Essential to prevent data loss during hardware or software failures
    • Access Control: Critical to allow authorized users to consistently access the system
    • Persistence: Data needs to remain consistent even after changes or upgrades occur

    Developing a Database Application

    • There is a defined process that includes: conceptual, schema, and physical design phases. The DBMS and its related system characteristics also play a vital role in creating the database application

    Classification of Database Systems

    • Categorisation of database systems can be based on:
    • Recent Past technologies: Hierarchical and Network databases
    • Current mainstream technologies: Relational databases
    • Future mainstream technologies: Object-oriented, object-relational, and deductive databases
