Introduction to Informatica vs Datastage
We can observe that data is increasing rapidly. Data can be in any form like text, picture or some images. These data are structured or unstructured. Data comes from different sources. It is very difficult to understand each data for the users. Here comes the major role of the Informatica and data stage tool to understand the data. Informatica is the platform that offers ETL tool services for data quality, data replication, etc. It will connect to different data sources, fetch data and process it. Datastage is the ETL tool which E(extract), T(transform) the data from sources and L(load) the data into targets. Data sources can be index files or sequential files, etc. It provides data analysis to the end-users.

Given below are the top comparison between Informatica vs Datastage:
Key differences of Informatica vs Datastage
Let’s discuss some of the major differences between Informatica and Datastage:
Informatica
- Informatica is known as Informatica power center and it provides ETL processing for applications used in the enterprise-level data warehouse.
- Data can be delivered to the user in a real-time approach.
- It is used for cleaning and modifying a huge amount of data from one system to another.
- Enterprise who needs to set up a data warehouse requires an ETL tool like Informatica to move data from production to data warehouse.
- Error handling is supported partially.
- It offers step by step solution to create data integration.
- It offers reusability to reuse mappings and workflow which will improve performance.
- It offers 30 general transformations to process.
- It supports heterogeneous and homogenous sources.
Datastage
- Datastage plays the role of an interface between different systems. It is used in large organizations. For example, the Banking sector uses Datastage tool.
- In 2005 IBM has acquired with DataStage and it has firstly renamed to the IBM web sphere data stage and then renamed to IBM Infosphere.
- Data can be delivered to the user parallelly.
- It is used for processing and transforming a huge amount of data.
- The source or target is directly connected to the Enterprise.
- Error handling is supported fully or throughout.
- It offers a project-based integration solution.
- It offers reusability of the job but to do this make a copy of the workflow, compile and run.
- It offers 40 general transformation objects to perform any transformations.
- It supports homogenous sources only. The user might end up with the wrong transformation with heterogeneous sources.

Conclusion
We have seen the difference and working of Informatica and DataStage ETL tool. As per the difference and comparison gave above, we can conclude that both the tools are working efficiently in their way. Both tools are providing good services for an organization. It is the user’s choice of which tool to use.
