Briefly discuss the OLAP architectural styles with and without data marts.

Program Plan Intro

Online Analytical Processing (OLAP) architecture:

  • The components of OLAP client/server architecture are as follows
    • OLAP Graphical User Interface (GUI) which is used for establishing communication between the end user and the computer system.
    • OLAP Analytical Processing Logic (APL) is required for performing difficult transactions between the client and the server.
    • OLAP Data Processing Logic (DPL) is used for performing data analysis in the data warehouse.

Data Mart:

  • Data mart is the subset of the data warehouse that focuses on the particular subject.
  • It is modified for decision making application and restricted in scope.
  • Performance for well-defined uses is optimized using the single or couple of queries.
  • Data mart optimizes the performance for well-defined uses as a single or couple queries.

Explanation of Solution

OLAP architecture styles with data marts:

  • The data marts are used for implementing the OLAP architecture with minimum amounts of data packets and refer to the data which is subject oriented.
  • It requires synchronization of the data frequently to access the data with high processing speed...
