In the previous chapter, we discussed how to extract data from a source table and transform that data using SQL programming statements. This is a very traditional approach and works well for many professionals, particularly SQL programmers, but can feel cumbersome and tedious to work with. I hav...

Integrate your MySQL data using Devart SSIS Data Flow Components. This solution simplifies the process of connecting and managing your MySQL data, so you can ensure smooth data flows between MySQL and other platforms. Thus you can improve your data-related operations and maintain data integrity acro...
If the ETL is a simple data feed, then oracle can do that without any challenges using PL/SQL. However, for large volumes and/or complex transformations (e.g. check for existence, applying fuzzy logic, etc), SSIS can definitely simplify the process (especially if built & deployed on a 6...

SSISTester is a framework that helps in the unit and integration testing of SSIS packages. It also helps to create ETL processes in a test-driven environment which thereby helps to identify errors in the development process. There are a number of packages created while implementing ETL processes...
We have a long running (10+ hrs) legacy daily ETL process relying on SQL Server DB snapshots for error recovering. I like to get some suggestions on how to rewrite the ETL process wihtout depending on DB snapshot. Existing Logic in SSIS looks like this:...

Instead of using one large computer to store and process the data, Hadoop allows clustering multiple computers to analyze massive datasets in parallel more quickly. It offers four modules: Hadoop Distributed File System (HDFS), Yet Another Resource Negotiator (YARN), MapReduce, and Hadoop Common....
Using an ETL tool helps ensure data accuracy, reduces manual work, and speeds up the process of moving data into PostgreSQL for insights or reporting. Also, take a look at how the process of ETL works step-by-step to get a detailed understanding of the process. Key Considerations while cho...
