What is the difference between a data warehouse and a data store?
In order to denote the contrast with a data mart, a full-blown data warehouse is often called an enterprise data warehouse to emphasize the organization-wide aspect. An operational data store (ODS) is another way of dealing with the disadvantage of data warehouses not containing up-to-date data.

ETL is the Extract, Transform, and Load process for data. ELT is Extract, Load, and Transform process for data. In ETL, data moves from the data source to staging into the data warehouse. ELT leverages the data warehouse to do basic transformations.
What is difference between OLAP and OLTP?
OLTP and OLAP: The two terms look similar but refer to different kinds of systems. Online transaction processing (OLTP) captures, stores, and processes data from transactions in real time. Online analytical processing (OLAP) uses complex queries to analyze aggregated historical data from OLTP systems.
