A Place For Your Query Needs What is Qstore? A revolutionary application to replace the FoxPro logic check component of the Lung Study database. And more. . . Qstore Features Standalone application. Engine written in C# and VB.NET It’s a “superstore” that manages little XML “stores” stocked with SQL ad hoc queries. Extremely easy to use. What is XML? XML stands for “eXtensible Markup Language” XML files are text-based, independent of propriety formats, and can “talk” to different programs/languages. XML files are de facto data carrier across the web. Before Qstore Logic check queries were hard-coded into programs thus they were difficult to maintain (i.e. add, delete, modify, etc.) After Qstore QStore manages queries stores saved in the lightweight XML format. Qstore runs these ad hoc queries against any database of choice. User Guide Brief glance also acts as a quick user guide. Qstore is so easy to use, it masks all its high-tech construction. Fig. 1 – Click the button to open a store. Fig. 2 – The store is a XML document. Fig. 3 – Existing SQL queries are pulled up for editing. Fig. 4 – Click the button “Get Database” to connect. Fig. 5 – Select a MS Access database of choice. Fig. 6 – Once connected, a list of tables will be displayed to confirm. Fig. 7 – Click the button to run the current displayed query. Fig. 8 – Query results could be previewed for printing. Fig. 9 – Print preview. Fig. 10 – Click on the button to save changes to queries. Click “Save As” to save the XML store to a different name thus duplicating it. Fig. 11 – Button “Execute Query” allows the user to be interactive with a query while the button “Run Store” powerfully runs the whole batch of queries without any interaction. Make sure existing queries are correct syntactically before clicking this button. Qstore Requirements Runs on Windows. .NET Framework (readily available for download from MS) pre-installed. To add/edit SQL queries, users needed to be versed in SQL. Just to run existing queries, no SQL skill is needed. Immediate Uses We are testing Qstore on the current Lung dataset for feedbacks and fine-tuning. The Lung Teleform dataset is to be tested on next. Future Releases of QStore Include more store organization. Little routines to connect to SQL Server, Oracle databases.
