Oracle Data Integrator Interview questions for experience

Explain what is ORACLE DATA INTEGATOR? why is it different from the other ETL tools.

Ans 1: ORACLE DATA INTEGATOR stands for Oracle Data Integrator. It is different from another ETL tool in a way that it uses E-LT approach as opposed to ETL approach. This approach eliminates the need of the exclusive Transformation Server between the Source and Target Data server. The power of the target data server can be used to transform the data. i.e. The target data server acts as staging area in addition to its role of target databasel. While loading the data in the target database (from staging area) the transformation logic is implemented. Also, the use of appropriate CKM (Check Knowldege Module) can be made while doing this to implement data quality requirement.

Q3.How will you bring in the different source data into ORACLE DATA INTEGATOR?

you will have to create dataservers in the topology manager for the different sources that you want.

Q4.How will you bulk load data?

In ORACLE DATA INTEGATOR there are IKM that are designed for bulk loading of data.

Q6.How will you bring in files from remote locations?

We will invoke the Service knowledge module in ORACLE DATA INTEGATOR,this will help us to accesses data thought a web service.

Q7.How will you handle dataquality in ORACLE DATA INTEGATOR?

There are two ways of handling dataquality in ORACLE DATA INTEGATOR....the first method deals with handling the incorrect data using the CKM...the second method uses Oracle data quality tool(this is for advanced quality options).
