Database and Files Review

28 August, 2015 - 12:29

If the systems documentation gathered during the internal literature review is accurate, it gives us an understanding of the way a system is supposed to operate (the formal system). But, because this documentation often changes more slowly than the actual system, it is often out of date. Therefore, information from documentation must be supplemented by that gleaned from other techniques that tell how a system really operates currently (the informal system). An analyst can review an organization’s database and paper files related to events processing; this is called a database and files review. Examples of items an analyst might review include a paper file of vendor invoices and inventory master data.
