    Study Notes

    Databases and Database Users

    • Databases are essential components of modern life, impacting many daily activities.
    • Examples include banking transactions, travel reservations, online shopping, and supermarket purchases.
    • These interactions involve accessing databases, which hold information, often textual or numeric.
    • Recent technological advances have led to new database applications.
    • Social media sites, like Facebook and Twitter, necessitate big data storage systems (NOSQL).
    • These systems also support cloud storage services.
    • Databases are used in various fields, including image and video storage, weather data, and business analysis.
    • Database search techniques improve internet search results.
    • Databases have specific characteristics. They represent real-world aspects ("miniworld").
    • Changes in the miniworld are reflected in the database.
    • A database is logically coherent and meaningful.
    • It's designed for a specific purpose and users.
    • Large databases require databases management systems (DBMS).
    • Databases range in size and complexity.
    • Examples include library catalogs, Amazon.com.
    • Databases can be computerized or manual.

    Database Management Systems (DBMS)

    • DBMSs are computerized systems facilitating creation and maintenance of databases.
    • DBMSs handle database definition, construction, manipulation, and sharing amongst users and applications.
    • DBMSs store meta-data (database definitions) for data types, structures, and constraints.
    • DBMSs manage data storage, manipulation (queries, updates, reports), and concurrent access.
    • Database protection against crashes, unauthorized access is crucial.
    • Database life cycles and maintenance are vital for long-term use.

    Database Example

    • A university database example includes files for students, courses, sections, grades and prerequisites.
    • Each file contains records of specific data types (e.g., name, student ID, course name).
    • Database manipulation includes queries and updates.
    • Examples include retrieving grade reports, changing student classes, creating new sections.
