To perform initial configuration of the Adapters off-site, it is important for data gathering purposes to obtain samples of past data. These samples must be of the same structure as that of the data that later appear incoming from the actual system from which CA Business Service Insight needs to retrieve data. In addition to the samples, the Data Source Expert should learn about the data source from the data source owner in order to be able to clarify the following issues:
Database, file, stream or other.
Where is it? How to get there (connection details)? Security obstacles? Platform?
How are files named? (is it a file-based data source) How are tables named? Table fields names?
When can it be accessed? When should it be accessed (load considerations)? Continuous update or once per X time? For how long is it persistent?
Is data accumulating? Is data overwritten? Is an archive kept?
How much historical data is available?
Current volume of data? Growth rate? Predictions?
How is data organized within data source? What are the data fields? What are the table names? What separates data fields?
Does the adapter get data or data is gathered by the Adapter?
