Profiling

Profiling displays a summary of the data found in a database. The summary can be used for such tasks as; database optimization and data migration. Select the columns and tables that you wish to profile from the database tree on the left hand side of the screen. Then activate the profile feature by either going to the "Profile" menu and selecting "Profile...", or by right clicking on a selected item and select "Profile.." from the context menu, or by selecting the Profile Icon in the Advanced Tool icon bar. If there is still an existing Profile window, the new profiling results will be added on to the existing window, otherwise, the resulting profile will be displayed in a new window.

Table View

In the profiling window, the profiling information is sortable. Simply click on the column header and it will sort the data by ascending or decesending order. In addition, if you place your mouse pointer over a most frequent cell, it will display the value and frequency of the most recurring items in the column. You can narrow down the results by using the search bar on the top right corner of the profile window. To delete columns from the profile result, simply select the desired columns and press the "Delete" button. As for refreshing the data within the profile table, select any one of the columns within the table and hit "Refresh". This will update the contents of the whole table. If you wish the save the profile results, you can highlight the desired columns to save, and click the "Save" button. If no column is selected, the Architect will save all the displayed results. You have the option to save it in CVS, PDF or HTML format.

Besides the tabular view, there is also the graphical view. Simply click on "Graph View" tab on the top to switch. On the left side of this window, you can select which column you want to profile. In the middle, it will show statistics about that particular column. It will also display the most frequent 'n' values and its frequency within the table. The pie chart on the right displays the portionality of the most frequent 'n' values in the column (the value of 'n' can be set in the "Project Settings" under the "File" menu).
