In this Data Warehouse Testing instructional exercise, you will learn: What is ETL.
ETL represents Extract-Transform-Load and it is a course of how information is stacked from the source framework to the information distribution center. Information is extricated from an OLTP data set, changed to match the information distribution center pattern and stacked into the information stockroom data set. Numerous information distribution centers additionally consolidate information from non-OLTP frameworks, for example, text documents, heritage frameworks and bookkeeping sheets. For instance, there is a retail location which has various offices like deals, showcasing, planned operations and so on. Every one of them is taking care of the client data autonomously, and the manner in which they store that information is very unique.

Presently to really look at the historical backdrop of the client and need to understand what the various items he/she purchased inferable from various showcasing efforts; it would be extremely drawn-out.
The arrangement is to utilize a data ware house to store data from various sources in a uniform construction utilizing ETL. ETL can change disparate informational collections into a brought together structure. Later use BI instruments to determine significant experiences and reports from this information. The accompanying chart in this ETL testing instructional exercise gives you the ROAD MAP of the ETL Testing process stream and different ETL testing ideas: What is ETL Testing ETL testing is finished to guarantee that the information that has been stacked from a source to the objective after business change is exact. It additionally includes the check of information at different center stages that are being utilized among source and objective. ETL represents Extract-Transform-Load. ETL Testing Process Like other Testing Process, ETL additionally go through various stages. The various periods of ETL testing process is as per the following Step by step instructions to Create ETL Test Case
ETL testing is an idea which can be applied to various devices and data sets in data the executives business. The target of ETL testing is to guarantee that the information that has been stacked from a source to objective after business change is exact. It likewise includes the confirmation of information at different center stages that are being utilized among source and objective. While performing ETL testing, two reports that will constantly be utilized by an ETL analyzer are ETL planning sheets :An ETL planning sheets contain all the data of source and objective tables including every single segment and their look-into in reference tables. An ETL analyzers should be OK with SQL inquiries as ETL testing might include composing enormous questions with numerous joins to approve information at any phase of ETL. ETL planning sheets give a critical assistance while composing questions for information confirmation. DB Schema of Source, Target: It ought to be kept convenient to check any detail in planning sheets.
