    Study Notes

    Knowledge Age

    • Peter Drucker introduced the concept of the 'knowledge age' in 1959.
    • A key characteristic of knowledge is that it can be derived from old knowledge.

    Databases

    • Smartphones have GPS functionality that tracks your whereabouts.
    • A database that supports data distributed across different sites is known as a distributed database.
    • A desktop database is a database that is used by an individual on a single computer.
    • A multiuser database that supports hundreds of users across many departments in an organization is an enterprise database.
    • A database is classified as single-user or multiuser based on the number of users who can access it simultaneously.
    • In a single-user database, only one user can access the database at a time.
    • When a multiuser database supports fewer than 50 users, it is typically classified as a workgroup database.

    Data Types

    • Data best suited for deriving monthly totals and average sales is structured data.
    • Semistructured data is commonly encountered and described as data that is not fully structured but has some level of organization.
    • Unstructured data has not been processed to the same extent as highly structured data.
    • Unstructured data typically found in corporations includes information such as emails, videos, and social media posts.

    Data Management

    • Data management is essential for proper decision-making and is a core activity for various entities.
    • Data management involves the generation, storage, and retrieval of data.
    • A discipline that focuses on data management is called data management.
    • Efficient data management typically requires a database management system (DBMS) and a data dictionary.

    Data Issues

    • A problem that arises from the introduction of computerized file systems is data inconsistency.
    • Data inconsistency can lead to incorrect decision-making processes.
    • A data anomaly is an error or inconsistency in a database system.
    • A data anomaly can be caused by inconsistent changes made to a database, also known as data corruption.
    • Data integrity is important for a database to maintain accurate and reliable data.

    Database Systems

    • The DBMS is often referred to as the heart of a database system.
    • The data dictionary is a component of a database system that stores relationships between data.
    • The purpose of using relationships stored in the data dictionary is to ensure data integrity.
    • The primary function of administrative utilities provided by a DBMS is to manage the database system.
    • A DBMS accepts end-user requests through a user interface, such as a query language like SQL.
    • A significant disadvantage of database systems is the cost of maintaining and updating them.

    SQL and APIs

    • Structured Query Language (SQL) is a special-purpose language used for managing relational databases.
    • The purpose of providing application programming interfaces (APIs) to procedural languages in a DBMS is to allow for customization and integration with other systems.
