Data Acquisition
Purpose
Data retrieval is one of the data warehousing processes in BI. BI provides mechanisms for retrieving data (master data, transaction data, metadata) from various sources.
The following sections describe the sources available for the data transfer to BI and how the sources are connected to the BI system as source systems. They also describe how the data can be transferred from the sources.
The extraction and transfer of data generally occurs upon request of BI (pull). The sections about the scheduler, process chain and monitor describe how such a data request is defined and how the load process can be monitored in the BI system.
The graphic shows the sources and transfer mechanisms described below:
