Introduction to Database Forms with HTML

A bit of history here: Microsoft Visual basic.net is superior to its predecessors, Visual Basic 6 and below. These predecessors were used in writing database programs. Also the latest version of Perl is superior to its predecessors; its predecessors were used for database programming.

Note: when you use C++, Java, Perl, Visual Basic, etc. to write traditional database programs, you use the language at the client, not at the server.

Now, is JavaScript known as a language for writing database programs? No! Can you compare the power of JavaScript today with the previous versions of Visual basic and Perl? Yes, very well; also, JavaScript is easy to use. JavaScript as it is today is a fine language.

Can you give JavaScript the power that state-of-the-art languages like C++, Java, Perl, and Visual Basic.net have? Yes; by giving our own interpretation to Internet protocols (HTML, HTTP, etc.), we can give JavaScript that power. Already, you have seen how I have easily turned the HTML TABLE element into a JavaScipt container. I hope you can now see that JavaScript, HTML, DOM and CSS together, give you a lot of power. In other words, these other standards complement or empower JavaScript.

So you can use JavaScript to write traditional database programs. Read on.

Forms

The form with the associated JavaScript code is stored at the server. When the user clicks a link at the client's browser, the form with its associated JavaScript is called from the server to the client.

Many database forms take up a small portion of the screen. When you have a database form on your web page, you can easily add decorations (e.g. images) around the form. This is not a straightforward task for document windows developed from the Windows API, even from studios.

I present the information in this series in such a way that as you read, you can be carrying out your own personal project; if you are new to programming, then you should try the codes I give in this series.

There are two basic types of forms, Single-Row Forms and Tabular Forms.
