Please read carefully and bid only if you understood the requirements. Please write "Yes I understood the project" in your project description.
This is an application development project. In short, this is where people upload their data and manipulate it to get desired information.
The UI and UI widgets are ready. The database design is done. What you need to do is create forms, validate them, store data in database, run queries and display data in UI widgets (like charts, tables). Then user manipulates data using jquery (drag and drop, sort, rearrange columns) and downloads resulting data as Excel file and the data is updated in database.
Data is entered both by filling forms and some data may be uploaded via excel files using phpExcel.
User login and user management is required. Each user sees his data only.
Please ask me for clarifications, if any.
