Database and Database Users: Chapter 1 Quiz

Database Fundamentals

• A database is a collection of related data that is stored in a way that allows for efficient retrieval and manipulation.

Mini-World

• In the context of databases, a mini-world refers to a small, self-contained portion of the real world that is being modeled or represented in the database.

Database Management System (DBMS)

• The primary purpose of a DBMS is to provide a way to define, create, maintain, and manipulate databases.

Limitations of Flat Files

• Problems associated with flat files include:
  • Data redundancy and inconsistency
  • Difficulty in accessing and manipulating data
  • Limited data sharing and security

Database and DBMS Relationship

• A database is a collection of data, while a DBMS is the software that manages and interacts with the database.

University Environment Data Type

  • Database schema
  • Data relationships
  • Data storage and access information
