Q-3

The main area where each of databases used are as follows:

Relational:

This type of DB stores data in Tables in the form of rows and columns. It stores structured data. This type of Databases is used in system where transactions are happening very frequently like banking system. As the data is being updated we need to keep data integrity among various operations.

Multi-dimensional:

This type of data has more than one dimension. This type of databases is used in system where we need faster retrieval of data and data update happens infrequently or data just added not updated. E.g. data warehouse applications, Analytics applications and Datamarts.

Object:

This type of database is used to store unstructured data. Each object item contains data and actions are used to process data.  Faster retrieval or search of data in this. Object Queries are used to access data.

Legacy:

Used to store unstructured data in the form of various types of files. Difficult to comprehend data and searching of data is very slow. Very different data format like csv, asn.1 , xml etc.
