You must understand the differences between Informatica and Teradata. Teradata is a an MPP (Massively Parallel Processing) database, with a certain degree of scripting and quick data movement, through the use of mLoad, FastLoad, Parallel Transporter capabilities. This allows faster retrieval of large amounts of data.
Informatica is an integration tool. It sources its data from flat files, databases, etc. and loads it into different targets. There is no storage of data at all. IT primarily is used for its export functions. Informatica can be thought to be like a transportation vehicle that moves items from one place to another. Teradata can be thought to be a warehouse.
- Informatica is a very robust platform and is easy to learn since there is no form of programming knowledge required to operate it.
- Extensive support is provided by the parent company, Informatica to a number of databases, such as tPump, ODBC Drivers, Parallel Transporter and so on.
- Create a faster software development life cycle, and due to the presence of a large number of accelerators and tools on the Informatica MarketPlace, support for applications is also higher.
- Surrogate keys are essential parts of databases and are not visible to end users. Through the use of share sequence generators, Informatica allows for faster generations of surrogate keys. In database software, this process is significantly slower.
- A new concept, known as Pushdown Optimization in Informatica enables the balancing of the data transformation load among the servers. This can help achieve optimal performance. The Integration Service converts the transformation logic into the appropriate SQL commands for the software to understand.
- With some code capability, the load between the database box and the ETL server may be balanced and is supremely useful for particular tasks when a fast disk is present on the server.
- Migrating from one database to another can sometimes prove to be tedious and difficult since different database systems have varying structures and formats. Informatica allows easy migration of projects, by appropriately modifying the ETL code, and thus providing an automated solution.
- The Workflow Monitor from Informatica allows easy and straightforward monitoring. This is crucial for identifying and recovery in the situations some jobs fail or if they are performing slowly.
- Informatica doesn’t require a yearly support fee to be paid apart from the cost of the license during the time of purchase.
- The jobs on Informatica can be arranged and categorised in a much simpler way in the form of worklets and workflows in folders. This makes the entire ecosystem much easier to analyse and make improvements.
Informatica is a powerful tool in the DBMS industry, especially for data integration. A host of companies are looking for specialists. Informatica interview questions will test one on their familiarity with the software and knowing how to make the best use of its numerous tools. To be able to use Informatica to its true potential, the intricacies of the software must be well understood. Lucrative growth opportunities at several companies are possible and are an excellent choice of specialisation.
