Once you have crafted your db and have a connection to it in DW you can then create the pages to manipulate the data in your db. You can use the DataAssist wizard to generate a set of pages to control the data in a particular table. When you start the wizard you just select the table you want to start adding data to and it will create an insert page to add new records, and update page to update the records, and search, results, details and delete pages for you as well.
Once the pages are created you can preview them in the browser or put them on your live server to make use of them and start adding data.
