It would be great if i had your feedback on the below project (if this is technically possible, the details in order to operate and your proposals).
1.1. What i have: an ERP working with DBF files (not a database)
1.2. What i need: a mobile (Android) application to read several sql queries on my mobile
1.3 The app must operate on several mobile devices, concurrently
[1.4] There must be a Configuration screen (by pressing "Settings" button on mobile device), with an administration password, where a user can add "Parameters", text strings (name and value). These must be set and stored on the mobile device. See issue 2.5 below for its usage
2. INPUT - SQL QUERIES:
2.1. The mobile app will have a drop-down list with the available sql queries and a button "Run" to execute and display the result of the query
2.2. There must be an easy way to input several sql queries (eg. in a hosting server or in the mobile app or in any other you propose)
2.3. The sql queries must stay stored for easy management (eg. in different text files on a hosting server or in a mobile local / remote database or in any other way you propose)
2.4. The app must operate independently of the sql queries, the queries must be full sql queries
[2.5.] When a parameter name is used in sql queries, the query must be executed using its value in the current mobile device. Is this possible?
3. TECHNICAL ISSUES:

4. PROJECT DETAILS:
