    Study Notes

    Lesson 2: Database Processing

    • Database processing involves converting data from tables to big data formats.
    • Businesses of all sizes use databases for organization and management of data.
    • Business professionals frequently interact with databases for various tasks, including use, purchase, and design.
    • Having a basic understanding of database processing is a critical skill in today's business environment.
    • Minimum knowledge equates to understanding fundamental terms and concepts.

    Learning Objectives

    • Q1. Why do business professionals need to have minimum knowledge of database processing?

      • In 2024, fundamental understanding of database processing is essential for any business professional.
      • Businesses store data in collections called databases for organization.
      • Business professionals use, purchase, and design databases frequently.

    • Q2. What is a DB?

      • A database (DB) is an organized collection of data stored in a computer, with defined elements.
      • Data needs to be organized for information extraction.
      • Data must be well structured for useful information.
      • Databases are essential for storing and managing data.

    • Q3. What is SQL?

      • SQL is a language used to query and manipulate a database.
      • It lets you select specific data, modify data, create database structures, and authorize user access.
      • SQL is convenient for extracting information from databases.

    • Q4. What is a DBMS?

      • A database management system (DBMS) is an application tool that handles a database.
      • It creates, structures, processes, and manages databases.
      • DBMS tasks include data security, record management, and fault-tolerant operations.

    • Q5. What is DB Processing?

      • Database processing is the use of applications to manage a database.
      • Applications handle data entry, structuring it into tables, graphing and reporting.
      • Applications can include forms, reports and queries.

    • Q6. How is the building of a DB done?

      • Building a database involves data modeling and database design.
      • Data modeling logically represents database data.
      • Database design transforms the data model into a database structure.

    • Q7. Why is NoSQL DBMS becoming important?

      • Growing data volumes, high velocities, and great data varieties require more sophisticated management.
      • Relational database systems struggle to handle big data effectively.

    Exam Question

    • Q. Which of the following is NOT a characteristic of Big Data according to the 4v model?
      • Viability is not a characteristic; veracity, velocity, and volume are correct characteristics.
