I need to develop a software application, that will be used for following tasks
1- extracting required data from different DBMS (Oracle, SQL Server, MS Access and even from MS Excel)
2- make a data file (can be Excel file or Access file)
3-Record all Data from this data file into MS SQL server
which plateform can be used for this (I am good at VB6 and MS Access programming).
can any web technology like client side JAVA script, be used or any other suggestion?
I want to make this application flexiable enough to extract data from any operating system like windows Server, XP/XP professional or windows 7, and insert that data into SQL Server.
Please give some suggestions.
