APEX: How to link application log-in credentials to a table in back-end database <p>I have made a database and now I am trying to make a front-end application using oracle apex 4(default with oracle-xe 11g). I have included the following table for user credentials in my database.</p> <pre><code>Manager(managerid{PK},name,username,password) </code></pre> <p>I know I can create many end-user accounts from the apex for an application. But, users of application will be managers only and I have a table for them in database so it would be illogical to create separate accounts and information when I have them already in database. </p> <p>My question is, how can I link the authorization of front-end application with the above table? </p> <p>Regards</p>
