Advantages of Datastage

Ability to join data both at the source, and at the integration server and to apply any business rule from within a single interface without having to write any procedural code.

Common data infrastructure for data movement and data quality (metadata repository, parallel processing framework, development environment)

Disadvantages of datastage

Big architectural differences in the Server and Enterprise edition which results in the fact that migration from server to enterprise edition may require vast time and resources effort.

Might be expensive as a solution for a small or mid-sized company.
