5. Differentiate between a file processing approach and the database
approach.

File processing system- each department or area or area within an organization has its own sets of data files. Two major weaknesses of file processing systems are redundant data and isolated data.

Databse approach- many programs and users share the data in a database. The database approach reduces data redundancy, improves data integrity, shares data, permits easier access, and reduces development time.

A database, however, can be more complex than a file processing system, requiring special training and more computer memory, storage, and processing power. Data in a database also can be more vulnerable than data in file processing system.

6. Describe characteristics of relational, object-oriented, and
multidimensional databases.

Relational database-stores data in tables that consists of rows and columns

Object-oriented database (OODB)- stores data in objects;often use an object query language to manipulate and retrieve data

Multidimensional database-stores data in dimensions;allows users to access and analyze any view of the database data and no standard query language exists
