Description

Data Warehouse Concepts course describes the evolution of information management systems. You are introduced to data warehousing and business intelligence, and their role in data analytics. You also get a brief introduction to modern data analytic technologies like machine learning, artificial intelligence (AI) and big data. The professionals will learn to define the Data Warehouse concepts and terminology with focus on Analytic Views. They gain knowledge about the basics of data modelling and the different techniques used for data modelling. Towards the end of the course, they get introduced to the ETL and EL-T processes for extracting, transforming, and loading data in a Data Warehouse.

Radiant Techlearning offers Data Warehouse Concepts Training Program in Classroom and Virtual Instructor Led/Online mode.

FAQs

Q: What is the purpose of Data Warehousing?

 

A: Data Warehousing is an electronic data management system which supports business intelligence and development activities especially analytics. They support analysis of performing enrolling and queries and could store large amount of analytical data.

 

Q: What are the difference between ETL and ELT?

 

A: ETL and ELT preferably have two different types of staging areas, the difference between them is that in ETL staging areas are found within ETL tool, whereas in ELT the staging areas are found within data warehouse and database engine performs the transformations.

 

Q: Which ETL software tools are given most preference?

 

A: Some of the recommendable ETL software tools are :-

  • Xplenty
  • AWS glue
  • Alooma
  • Talend
  • Stitch
  • Oracle Data Integrator
  • Informatica Powercenter

 

Q: What is meant by analytical sandbox?

 

A: Analytical sandbox is typically an area carved out of existing data warehouse which provides required resources for supporting experimental and developmental analytical operation.

 

Q: Is there any difference between Data Lake and Data Warehouse?

 

A: Data likes and Data Warehouses are both widely used for big data storages. Data Lake is a vast storage of raw data which is not defined while data warehouse is the storage of filtered data already determined for specific purpose.

 

Q: Are there any classifications of Data Warehousing?

 

A: There are 3 main classification :-

  • Enterprise Data Warehouse
  • Operational Data Store
  • Data Mart
