BETA is a pure object oriented programming language developed by Scandinavian School in System Development, Nordic Universities.

This was released after a series of enhancements of their first object oriented language SimulaI which was a simulation language. Soon it was generalized into Simula67 which had the object oriented framework, and worked on the concepts of class, sub-class, virtual functions etc. This was enhanced by another object oriented language Delta that worked for system description; this meant it could express predicate logic and state changes. This was a non-executable effort and thus did not qualify as a language. So it was decided to design a programming language Gamma that works as Delta but is executable.

Eventually, Gamma was never made, rather Beta was made. While Beta was being made, it was realized that Beta was much more powerful than what Gamma would be or ever could be. Beta is a programming language like C++.

Currently, BETA is available on UNIX workstations, on PowerPC Macintosh and on Intel-based PCs. BETA has an optimum balance between compile time checking and run time checking. The type cast checking is done at compile time, however, for the entire set of type check and type conversion to be done at compile time requires a lot of time and thus increases the complexity of a program. Thus, an optimum balance has been made.

BETA is a logical description of the language. It works on the concepts of class, sub-class, virtual functions etc. It also contains transient variables, ones whose scope is program execution, and persistent variables, those whose values are retained in the disk space and are available at the time of next execution.

Sites that require users to log in to access certain information and/or purchase products add an additional layer of potential complication to the usability process. To avoid potential visitor confusion and the possibility for errors, it is important that any login process requires little or no thought on the part of the site visitor.

Once logged in, you must be sure that visitors are able to find the information they want and expect to find. My Account pages need to provide visitors with access and ability to view and change personal information, as necessary.

Login Access

Access to any login page (or the login form itself) should be available consistently across all pages of the site. Be sure the form or link is obvious and easily differentiated from other areas of the web page.

Security

If the information behind your login contains sensitive data, you need to use the appropriate security protocols, assuring visitors that that you take their information's security seriously.

Registration

If visitors are not already registered a link to a new user registration form should be present. It's also smart to have a global link to "register" for any new visitors to the site.

Account benefits

Non registered visitors should be treated to benefits of account registration. This information should be located on the same page as the new user registration form.

Lost password

All login forms should contain an option to reclaim passwords and/or username should they have been forgotten. This information must also be passed securely.

Remember me

You can provide additional convenience (though less security) by giving visitors the option of checking a "remember me" box which will allow them to stay logged in indefinitely.

Privacy

Provide a link to your sites privacy information/policy near the login form submit button or email field. This gives your visitors confidence that you will treat their information with respect.

Status

The visitor's "logged in" status should be displayed at all times with a ready access to logout at their convenience. When additional security is necessary it's a good idea to automatically log them out after a set period of inactivity.

Change info

Once logged in, visitors should have access to change their user information, including usernames, passwords, contact info, payment details, etc.

Change confirmation

Once the visitor has submitted their information to be changed, provide a confirmation screen that shows the old and new info. This prevents errors and helps insure information remains accurate.

Financial details

Provide links to relevant financial information such as transaction history, invoices, balances, payment methods, etc. Provide printable version of this information.

Up-sell opportunities

Visitors that are logged in provide you an interested, captive audience. Consider discreetly utilizing up-sell opportunities - without being overbearing.

Subscribed services

Provide visitors access to the information/services to which they are subscribed. Also provide additional subscription options, if applicable.

Information management

Allow users to change the way they receive information, providing alternate methods such as snail mail, HTML or text based emails or to turning off communication entirely.

When visitors create an account with you they are making a commitment to you to enjoy the services or information that you provide. It's important not to let the usability process break down after visitors are committed. In fact, it's even more important to treat registered visitors respectfully and appropriately, ensuring they have access to the information they need. This develops long-term relationships and keeps them coming back.

Here's an analogy for you. Yesterday, I was working my butt off in the gym on the cardio machines, panting wildly with sweat dripping off me and my face as red as a beet. Not the most attractive sight, but I figure, you're at the gym to work out right? I might as well "go hard" or "go home", as they say.

As I looked around me, I could see all these people simply going through the motions. There they were, minus perspiration in their shiny new lycra and expensive gym shoes, casually walking on the treadmill or lazily turning the wheels on a bike while reading a book or glued to the TV screens in front of them. Only a few seemed to be there for the actual purpose of working out. The rest seemed to be there to check out the talent or to simply keep up the appearance of fitness, while doing the bare minimum.

Huh? I don't get it. Why have these gym bimbos paid so much money for a gym membership and all the related gear if they aren't going to take full advantage of their investment?

Then it struck me - these gymbos were just like those companies who spend thousands of dollars on a shiny new website with all the bells and whistles like graphic design, blogs, shopping carts, web analytics, the lot and then fail to take advantage of it. I see it so often, regardless of company size. Web sites that could easily be bringing in loads of traffic and revenue simply wasting away because nobody can be bothered tracking visitor activity, analyzing trends or checking for search engine compatibility and usability.

These companies are simply keeping up appearances, investing heavily in Internet technology because their competitors are doing the same. But no thought has gone into the search engine compatibility of the site, how usable it is for visitors or whether it meets accessibility guidelines. They don't look at their site statistics, they don't check for broken links and they sure as heck don't investigate why their sites aren't converting traffic into customers. What a waste!

Is your web site working hard enough for you? Run it through the following 20 point fitness assessment to find out:

- Is your site fully search engine compatible? Are all your pages being indexed by the major search engines?

- Do you track your visitor statistics on a regular basis? Do you use the information provided by your visitor statistics to improve your site?

- Is your web site accessible to visually-impaired visitors? Does it meet the international standards set down by the Web Accessibility Initiative (WAI)?

- Do you know which sites and search engines provide you with the most traffic? Do you use this information to increase your traffic further?

- Do you track the source of all reported errors in your site statistics and fix them promptly?

- Do you know which keywords your site was found for in the search engines? Have you conducted keyword research to determine what search terms your target markets are looking for so you can optimize for them?

- Does your web site HTML code validate to W3 standards? Do you check for validation regularly?

- Does your site contain zero broken links? Do you check for and fix broken links regularly?

- Has your site been fully search engine optimized to integrate your target search terms into your Page Titles, META Tags and visible page text?

- Have you created and submitted an XML sitemap to Google Sitemaps?

- Have you created and submitted a sitemap to Yahoo Site Explorer?

- Have you checked to see if your site meets Google's Webmaster Guidelines?

- Do you measure your visitor sign-ups and conversions on a regular basis? Do you tweak your landing page copy to increase the conversion rates?

- Is your site navigation intuitive and are your visitors following the navigation paths you intended?

- Do you encourage feedback from your site visitors and provide an obvious way for them to provide such feedback?

- Are there at least 250 words of text on your home page to satisfy search engines?

- Does your site contain a visible, text-based site map to aid user navigation?

- Do you have an ongoing link building campaign running to secure more incoming links to your site and improve your site's link popularity score?

- Does your site have a high percentage of repeat visitors? Are the majority of your visitors staying on your site for more than a minute?

- Do your search engine referrals and site traffic figures grow each month?

Unless you can answer yes to all the questions in the above checklist, your web site is not working hard enough for you and needs a workout. Get to it!
