Informatica Exam PR000007 Topic 3 Question 110 Discussion

Actual exam question for Informatica's PR000007 exam

Question #: 110
Topic #: 3

Why should you use PowerCenter Metadata Exchange (MX) views rather than querying the PowerCenter repository tables directly- i.e. the ones that begin with OPB_?

AQuerying the PowerCenter repository tables directly is a violation of the PowerCenter license and terms of use.

BPowerConter repository tables store most data in proprietary binary format and hence are not directly readable. This binary format improves performance.

CStored (hard-coded) queries against the repository tables may become invalid upon a repository version upgrade due to the fact that the repository table structures may change.

DIt is not possible to query the repository tables directly.

I also heard that stored queries against the repository tables may become invalid after a repository version upgrade, so using MX views is more reliable.

Additionally, querying the repository tables directly may lead to performance issues as the data is stored in a proprietary binary format.

Using the MX views is definitely the way to go. Querying those repository tables directly sounds like a recipe for disaster, especially with all the potential version changes.

I agree with Jenise. It's important to follow the terms of use to avoid any legal issues.

I think we should use PowerCenter Metadata Exchange (MX) views because querying the repository tables directly may violate the license.
