We have a MySQL->Oracle ETL using Informatica that works great for all statements except DELETE. Unfortunately, the DELETE makes the record go away such that Informatica never sees it again to remove/expire it in Oracle. How have people gone about recording MySQL DELETE statements? The tables are InnoDB (ACID-compliant) with unique pr...
I am trying to use the MS SQL Server 2005 Import/Export tool to export a table so I can import it into another database for archival.

What options should I choose to e...

Hey guys, I have recently been exposed to some ETL tools such as Talend and Apatar and I was wondering what exactly the purpose/main goal of these tools is in laymans terms.

I have data moving through the pipeline and being written to the db. However I can't seem to figure out how to enable logging. the log4net assemblies are there, the log4net object...

To "BeginTran + Commit" or not to "BeginTran + Commit" EDIT: I have one master package calling 4 other packages - is it possible to roll them all up into one transaction? ...

We have been using Talend 3.1 for a few months now. However, we are looking at possibly switching to the latest MapForce. Simply because it compiles to a .Net solution and we are otherwise a .Net house. That being said Talend is extremely easy to use and extend. The Talend jobs make it very easy for new developers to understand the job a...
I am writing an ETL (in python with a mongodb backend) and was wondering : what kind of standard functions and tools an ETL should have to be called an ETL ?

I have several files about 5k each of CSV data I need to import into SQL Server 2005. This used to be simple with DTS. I tried to use SSIS previously and it seemed to be about 10x as much effort and I eventually gave up. What would be the simplest way to import the csv data into sql server? Ideally, the tool or method would create th...

We have a legacy app that needs to be rewritten, and due to its size, we can only do it bit by bit over several years. The idea is to keep developing new features for the new app while still providing access to unimplemented features via the legacy app. We're looking for recommendations for ETL tools that provide a GUI for the actual in...
