One of the other effects that this has on converting data into the software application is that the conversion programs cannot read the data directly from flat files stored on the server. All records that are to be loaded into the software data structure must first be loaded into interface tables within the Oracle database itself, before being moved to the tables owned by the P2K user. Once the information has been loaded in these interface tables it can be edited or reported with the supplied screens and reports. Both the screens and report can be accessed from within the menu structure designed into the Conversion application.

Loading the software conversion data into the interface tables gives us the ability to verify that the loaded data is correct and in the format that the conversion programs require, prior to altering the tables. This also allows us to perform any additional translation of the data that could not be performed prior to loading the information into the tables. Several third party applications are capable of reading, manipulating and storing the altered data back into Oracle tables. The use of SQL scripts to perform the same translation of the data is also available, and can be done with the utilities provided by Oracle.

The application screens allow the users to key in all of the client data into the application in a structured format. The records need to be entered into the screen in a specific order and the data builds onto one another as it goes. If the quantity of records to be entered into some of the tables is small, keying them in will actually be faster that loading them in. However, there are a number of tables that need to have the records loaded into them in bulk.

The purpose of these conversion utilities is to provide this bulk load mechanism for the application. The records will still have to be loaded in the table in the same order that they would have to be keyed in. This is actually dictated by the data integrity constraints defined in the database, as part of the application configuration.

During the initial installation of the application environment, three separate database where created. One of these databases will be called CONV or PROD, depending on the specific installation of Oracle and the application.
