Oracle Data Integrator - The real data integrator
- Oracle Data Integrator nearly addresses every data issue that one can expect. Oracle Data Integrator is tightly integrated to the Oracle Suite of products. This is one of the major strengths of Oracle Data Integrator. Oracle Data Integrator is part of the Oracle Business Intelligence Applications Suite - which is highly used by various industries. This tool replaced Informatica ETL in Oracle Business Intelligence Applications Suite.
- Oracle Data Integrator comes with many pre-written data packages. If one has to load data from Excel to Oracle Database, there is a package that is ready available for them - cutting down lot of effort on writing the code. Similarly, there are packages for Oracle to SQL, SQL to Oracle and all other possible combinations. Developers love this feature.
- Oracle Data Integrator relies highly on the database for processing. This is actually an ELT tool rather than an ETL tool. It first loads all the data into target instance and then transforms it at the expense of database resources. This light footprint makes this tool very special.
- The other major advantage of Oracle Data Integrator, like any other Oracle products, is a readily available developer pool. As all Oracle products are free to download for demo environments, many organizations prefer to play around with a product before purchasing it. Also, Oracle support and community is a big advantage compared to other vendors.
Cons
- The Java framework does not stand up to the mark. It crashes frequently. There is a long [list] of improvements required in terms of client tools framework.
- Though Oracle Data Integrator lets people login from a web browser to monitor different activities, it crashes and performs very poorly when logged in out of network. Even Oracle Data Integrator client tools don't perform well on a remote desktop. Increasing Java buffer is one of the workarounds, that might work. So, a better client tools and interface is a big advantage.
- Navigation is another pain area. It is very difficult to find out the precise error, in case of a failure, in Oracle Data Integrator. In Informatica, it is a cake walk to pull out a session log that shows up the exact reason for failure. Although Oracle Data Integrator is tightly integrated to database, it is very poor in providing the exact error at high level. One has to dig through to get it.
