    Study Notes

    Advantages of RDBMSs

    • RDBMSs provide structured data organization, allowing for efficient data retrieval and management.
    • They support SQL, enabling complex queries and transactions.

    NoSQL Representation

    • NoSQL databases represent unstructured or semi-structured data, accommodating diverse data models such as documents, key-values, wide-columns, and graphs.

    Data Representation in Object-Oriented Databases

    • Object-oriented databases utilize objects to represent data, encapsulating data and behavior, and support inheritance and polymorphism.

    Relational Databases Key Assumption

    • A foundational assumption is that data can be structured into tables, which can be related to each other through foreign keys, ensuring data integrity.

    Data Storage in Object-Relational Databases

    • Object-relational databases combine features of both RDBMS and object-oriented databases, storing data in tables while also allowing for object-like data structures.

    Main Advantage of NoSQL Databases

    • NoSQL databases excel in scalability and flexibility, enabling horizontal scaling and easy handling of varied data types.

    Object-Oriented Data Representation

    • Data is represented as objects that can contain both attributes and methods, allowing for a more intuitive modeling of real-world entities.

    Key Feature of Object-Relational Databases

    • They enable the storage of complex data types such as arrays and user-defined types, bridging the gap between relational and object-oriented approaches.

    Relational Databases Key Assumption (Repeated)

    • The essence remains that structured, tabular relationships among data entries are crucial for maintaining coherence and organization.

    Relational Database Engines Offer

    • Relational database engines provide transactional support, data integrity, and various data manipulation capabilities, facilitating efficient management of relational data.
