Project Description

Dear all,

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


2.1. 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?


3.1. Write down all technical specifications needed: hardware, software, hosting server, database, etc

3.2. Please clarify the data flow in technical terms


4.1. Payment will split in at least 2 milestones, a small in advance and the remaining on project full delivery. Please clarify your payment terms

4.2. How many days you need to develop / test and deliver the full project?

Issues in [] are optional or part of a second phase development, please give a separate cost proposal for these.

Please refer to the numberings for any questions / clarifications.

Thank you in advance for your feedback and proposals.
