How to use Data Components (Data Source) in OBIEE

1.Data Components are composed of any source that can be accessed via an ODBC connection.

2.Transactional databases can be used to source data; however, the Normalized table structures typically do not perform well when accessed via an OLAP tool like OBIEE.

Stating that a source is ‘ODBC compliant’ should not be enough of a reason to use it as a source.

Guidelines for what is considered a ‘source’ should be established by a steering committee.

For example, some companies have stated that Access Db’s, spreadsheets and flat files should never be considered a source since they are not a ‘mature’ source.

3.An Analytical Database (data warehouse, data mart) should be a collection of analytical data in sets of star and/or snowflake schemas.

4.Other source data can be Access Db’s, Excel Spreadsheets, etc.

Using these types of sources to do prototyping and proof of concepts is quick and easy.
