Data Collecting In order to structure data, one must first gather data elements and establish the domain to which this data applies. This chapter deals with raw data information that comes from the users or other sources, and the techniques that can help us to build a comprehensive data collection. This collection will become our input for all further activities like data naming and grouping. To be able to build a data collection, we will first identify the limits of the system. This will be followed by gathering documents in order to find significant data elements. The next step will be to conduct interviews with key users in order to refine the list of data elements. All these steps are described in this chapter. System Boundaries Identification Let’s establish the scenario. We have been called by a local car dealer to submit a proposal about a new information system. The stated goal is to produce reports about car sales and to help track the car inventory. Reports are, of course, an output of the future system. The idea hidden behind reports could be to improve sales, to understand delivery delays, or to find out why some cars disappear. The data structure itself is probably not really important in the users’ opinion, but we know that this structure matters to the developers who produce the required output. It’s important to first look at the project scope, before starting to work on the details of the system. Does the project cover: The complete enterprise Just one administrative area Multiple administrative areas One function of the enterprise
