Source data for analysis overview

For a given analytical project, you need one or more data sources for analysis.

Based on your project objectives and expected goals, you should have a good understanding of what data sources are needed. However, it is likely that the level of knowledge across different sources will range from very high for active, operational databases to very low for sources such as out-sourced vendor packages or external data. The level of anticipated knowledge for a given system might impact the approach for analysis.

A data source for IBM® InfoSphere® Information Analyzer might be a production database, an extract or replica of such a database, an external flat file, and so forth. It is assumed that issues of availability, access, and security have been addressed and that connectivity to the data source has been established as a precursor to analysis.
