How do you provide access to results without allowing users to modify the data?
Efficiency question :
Creating a report generator makes it possible to provide access to results without requiring users to work directly with the data used to produce them.
The data is retrieved and processed automatically according to established rules and then used to generate the reports. Users can therefore review the results without modifying the source data or the calculations required to produce them.
This approach helps protect data integrity and ensures greater consistency in the reports produced.
Key considerations:
The automation must nevertheless ensure that all required data is available before the report is produced.
In particular, avoid generating a report too early with incomplete data. For example, a report covering February that is produced on February 22 could appear to present results for the full month even though the period is not yet complete.
A good practice is to automatically include the report creation date in the footer. This allows users to know precisely when the results were generated and interpret the information accordingly.
Challenges:
To prevent users from modifying the data directly, its quality must first be sufficient to support process automation.
This work must be done upstream. Data loads and entered information should be properly controlled to reduce the risk of errors before the data is used in reports.
The earlier these control mechanisms are integrated into the process, the less users need to intervene manually in the data or in the results produced.
Technology:
When a programmed procedure is used to generate reports, it can also manage quality controls and formatting.
For example, a sales report could be designed to show twelve different products. If some products recorded no sales during the selected period, the procedure can automatically hide the corresponding sections so that only relevant information is displayed.
Programmed instructions should therefore do more than simply produce results. They can also perform validations and automatically adapt the report layout to the available data.
Developer's advice:
When designing the report generator, plan from the outset how users will need to view or receive the results.
A PDF output, for example, makes it possible to distribute a report without providing direct access to the data and calculations used to produce it.
Report delivery by email can also be built into the process. Different email types can be prepared in advance so the user can select the one appropriate to the situation and then automatically launch both report creation and email delivery.
This approach maintains control over the data and report-production process while simplifying access to and distribution of the results.
