    Study Notes

    Introduction to Databases, SQL, and DBMS

    • A database is an organized collection of data with definite elements stored in a computer, including tables, relationships with keys, and a data dictionary.
    • Excel is not considered a database because it only contains tables, not the additional elements of a relational database.
    • Structured Query Language (SQL) is a language used to query a database, allowing actions such as data manipulation, schema modification, and granting user access.
    • User access defines the privileges of a user, including data access, actions on data, and administrative permissions.
    • SQL is powerful as it allows for creating the database schema, inserting data, retrieving information, and providing user access.
    • SQL's simplicity is demonstrated by its syntax for querying data, involving selecting columns and rows, organizing and presenting them visually.
    • The SELECT statement is a fundamental instruction in SQL for querying data from a table.
    • In more complex cases involving multiple tables, SQL uses the JOIN clause to recreate the initial table using relationships.
    • A database management system (DBMS) is an application used to create, process, and administer a database, handling activities such as data organization, security, concurrency, fault tolerance, and recovery.
    • DBMS can be commercial or open-source, with Microsoft Access being an example of a personal DBMS, not an enterprise DBMS.
    • DB processing involves retrieving information from raw data stored in a database through the use of a DBMS.
    • The DBMS is a means to operate with the database, while the database itself is an organized collection of data with definite elements.
