The interface is designed as an industry-standard Web service. One significant benefit to customers who require access beyond the Performance Manager user interface is that the API will remain consistent and compatible across future versions of Performance Manager, regardless of changes to the underlying database scheme. In addition, the API provides data views that go beyond what can be offered by single SQL statements (for example, cross-project queries).
A web service (HTTP/Get) interface has been built on top of the results repository. Customers do not need to interact directly with the results repository; they can interact with the API, which will remain compatible across major version changes. See the Silk Performance Manager API Help for full details.
