I am working with Delphi 5 enterprise and sql server7.
I am using ADO components for database connection.
There will be 4 to 5 user accessing the data simultaneously.
What all things I have to do so that all users gets all data, but if any user edits a record then that record should be no editable for other users.
I have no idea about developing multi user applications, so please explain to me what all things I must to ensure the quality of this multi user process.
