Knowing how javascript code gets executed in a browser will help us organize the libraries or functions for better performance. Javascript unlike the server side scripting languages like PHP, ASP, Perl is not compiled at the server side. It is sent as-is from the server to the browser client and it is the browser that interprets the code at the client side. The total size of the Javascript code and its organization will have a significant effect on the pages served at the client side which in turn will affect the performance of the page. Organize the libraries in such a fashion that you only have the needed functions associated with the page. You can consider this point right at the time of creating your template pages. This will reduce the number of javascript pages that are called from one page. (more…)

Click the Test button to ensure everything works fine and as expected. 5. The DSN "MyDSN" gets created for you when you click the "Ok" button. 6. Now, go to Access and create a database (e.g. MyAccessDB) 7. In Access, click "File > Get External Data > Import > and then choose "ODBC Databases" from "Files of Type" option. This will open a new dialog window asking you to "Select Data Source" 8. From the new dialog window, choose "Machine Data Source". This will display the DSN "MyDSN" which you have created earlier.
