Instead of using:

SELECT COUNT(*) FROM TABLE_NAME

… for each table in the database, we can query the system tables as below:

SELECT sysobjects.Name AS TableName, sysindexes.ROWS AS TotalRows
FROM 	sysobjects 
		INNER JOIN sysindexes ON sysobjects.id = sysindexes.id
WHERE TYPE = 'U' AND sysindexes.IndId < 2
ORDER BY sysindexes.ROWS DESC

Years after its development, it still continues to be the favourite ecommerce solution for customers globally. Many top entrepreneurs have picked Magento as their choice for an ecommerce website owing to its multiple advantages.

Let us see why the Magento Application is so popular.

Updates

Magento is one of those web applications that thoroughly believe in constant Upgradation. The parent company behind Magento regularly brings about updates to this application, eliminating previous bugs and malfunctions. Other eCommerce web applications are rather out-dated owing to a lack of regular maintenance updates. These updates that are based on the latest technologies help in giving the user a better experience.

Add-on Modules

Magento offers many add on modules that help in offering the end user multiple benefits. For example, with Magento you can offer discount couples, editing rates, product categories, sorting etc. It also enables you to see many reports that can help you identify and understand what the customer expects from you. You can get abandoned shopping cart reports and also details of SEO urls within your site.

It also enables you to sell the same product at different rates to a various set of customers.

Editing

Although some people maintain that Magento is more meant for a developer than a shop owner, it is actually quite the contrary, because Magento is extremely easy to edit. Magento is built to measure from 1 to a million, avoiding common downsides for developers. Code re-uses, maintainability, debugging, support, etc. are all huge and mostly expensive difficulties that eCommerce solutions providers must tackle. Magento makes them all a cakewalk.

Turnaround Time

If you are looking to install and run a shopping cart well within a fixed timeless, Magento is the baby! It is extremely easy to install and gets fully functional within days. If you know how to upload files on the internet, you can install Magento without any professional help. Creating a database and configuring various systems is also extremely simple. The good news about Magento is that if you are taking Web Web Development services from India, you can have your site up and running in a matter of hours ( of course please consider the speed of the internet!).

The time taken to go through the entire process is negligible. The process involves:
+ Designing the template layouts for the site,
+ Product/content entry,
+ Feature configuration,
+ Prepping a site for live-production

Online Support

There is a plethora of free online support readily available for Magento. Just get on any search engine and type your Magento query in the search, you will find numerous sites and threads addressing the issue and providing ready assistance absolutely free of cost.

With the kind of detailed support made available, launching a site is an absolute breeze and can be handled easily within days. Magento also allows for intense customization to ensure that your website is absolutely suited for your products and services.

They provide active support in troubleshooting any sort of problems. You will find blogs, threads and even videos that address Magento queries.

What’s more, you can also put up your own questions on these platforms and will be soon given a response on the same. Magento owes a huge portion of its success to this online community that relentlessly strives to bring about great Magento websites that help in making the world of technology much more accessible to people.

Conclusion

The most important thing for business owners today is to establish an online presence that stimulates a better growth and revenue generation. With the number of people bending towards an online shopping experience, it is about time you ventured in it.

Magnanimous Magento – Why it is so popular! is a post from: 4 Rapid Development

If you are a little interested in the world of CMS, you would have noticed that WordPress and Joomla are way more popular than Drupal, although Drupal is a really powerful CMS. Ever wondered why? Well, I did. Being in this field for so many years, it was quite easy for me to pinpoint exactly why this was happening.

Well, the obvious fact is that although Drupal really powerful, it seems a lot more complicated than the other two content management systems. It’s a vicious circle you know, because it is so powerful, it needs a certain level of web programming knowledge to handle it. Therefore, someone who realty understands and appreciates the potential of a strong and robust CMS will never blame it.

The Problem

The most apt phrase here is “one man’s meat is another man’s poison”; because web programming specialists love it for its massive range of customization options, but designers avoid it due to same reasons. Most of them get confused and think that Drupal theme design is an unattainable task.

If you are a serious developer, it should not at all be a tough task for you. But yes, let’s face it, if you are only acquainted with Photoshop, CSS and HTML, you can wave Drupal web designing a goodbye. Although dedicated developers have simplified the theming layer a lot in the recent years, it still needs the hands of a developer with good knowledge of PHP to make the most out Drupal.

If it is so hard, then why should designers and developers use it? They should, because it has stronger security features, has the capability to handle large websites and gives the freedom to update content within few minutes. If you hire a knowledgeable designers and expert developer for Drupal CMS web development, they can produce something exceptional.

Themes

Another hindrance in Drupal’s way is that, it is very difficult to find Drupal based themes. However, you can easily find hundreds of WordPress themes because it is so popular. It is looked upon as a great advantage for WordPress, however, people ignore the fact that Drupal websites are more original and customised because of the same reason.

Business owners have to become aware because, website designers (more often than not), buy ready-made (or even download free) themes, and then make minor changes in its overall look and sell it to them. Please become aware that if something such is happening then there is no originality in your work. Do a lot of research and remain cautious before you hire website designers. This is why I recommend using Drupal, because at least that way, you’d be sure of the authenticity of your website design.

Drupal for Newbies

Given this scenario, let me please make it clear that I am not saying greenhorns can’t work with this amazing CMS. But yes, it may take a lot of hard work and efficiency to develop the Drupal skills. Initially you can try by using grids to maintain a balance in the layout and opt for standard graphical elements. This powerful CMS has a default web form size and your personalized forms should match the specific aspects.

Conclusion

Some acquaintance with this CMS can change your opinion about Drupal as a CMS. As a developer, you must have the enthusiasm to venture into such an amazing content management system with great potential. Since there are very few Drupal developers, the demand for good Drupal Designers is very high. Use this to your advantage. Because it belongs to the open source group, it is absolutely free. What’s more, it is extremely secure. Drupal’s biggest quality is that it is a multi OS and server compatible Content Management System. I wouldn’t deny that WordPress and Joomla are great Content management Systems as well, but Drupal definitely has a very bright future.

Is Drupal a little too complex? is a post from: 4 Rapid Development

The popularity of PHP in today’s reign of internet needs no explanation. The rise that PHP has seen in the recent past is a result of its efficiency and cost-effectiveness. PHP has been used widely across various sectors, in different ways to serve a host of purposes. However, there are some things that one must take care of while using PHP. We have gathered a few words of advice from the greatest names in the business on the Internet.

Don’t use PHP for everything

The father of PHP, Rasmus Lerdorf himself states that PHP was developed as a problem solving script. It was not made to serve a variety of projects. The origin had more to do with catering to a practical web based problem rather than a cool new internet invention.

Therefore its usage should be limited to as much as required. Although PHP is one great tool to work with but, in case PHP fails to feel fit for one’s requirement, they should simply move on and use a language that is most suited to their nature of the product.

TO make PHP more scalable, more and more tables and MYSQL should be used

With WordPress is occupying the center stage, Matt Mullenweg has proved the metal of his PHP mastery. Mullenweg explains that using one colossal table is not as effective as using separate and individual MYSQL tables for each and every blog. That escalates your site’s scalability and makes your efforts towards it much more countable. Multiple tables and migrating data from them enable the blogs to run much faster. Together with some heavy caching, and clever database treatment, Matt has presented that tremendously popular sites like Facebook and WordPress.com too can handle the intensive traffic using PHP.

Beware of the User

David Child is an established specialist in PHP. He has worked in the UK for many development companies. He is also the man behind the scenes of the website called Added Bytes, which gives details regarding many programming languages.

Dave advises to write the source code keeping in mind that the users are no angels. They may just pick up stuff and try to clone/hijack your website. He explains secure ways of writing source codes on his website.

Batch Processing for Background processes

Jack Herrington, the IBM developer Works expert is a renowned writer in the field of PHP. His study indicates that Batch Processing should be used to enable the background processes to run by them.

There are some tasks which take longer to finish than the other tasks; however, spending extra time with them isn’t wise. He suggests using batch processes to let these programs continue and finish. He also suggests that instead of making it a complex mesh of by using too much threading on the servers, it is best that simple combinations of PHP, MySQL and Cron be used to get the perfect results.

Error Reporting should be turned on Immediately

David Cummings, the owner of a software company and an expert in content Management systems has won multiple awards in this field. He states that turning the error reporting on immediately pays off in the long run. Error reporting, more often than not, makes finding the actual reason of the error quite simple. This way you can locate and solve the problem as soon as possible.

When you can save yourself the agony of scouring for the bugs, then why not. Lay back and let PHP do its work. It will point at the bugs and save you so much time, you’d be thanking Rasmus!

Having said this, we can all mutually agree that PHP as a technology has so much to offer in its kitty, that with a little attention and a close eye for development, the web world is soon to expand into a universe and more.

PHP- Great People, Simple Advice is a post from: 4 Rapid Development

Golden Lock

The first way is to make sure that the golden lock is at the bottom of the browser (on the right side). This little lock shows that the website you are looking at is secure. You don’t have to worry about any of your personal information being shared with other companies. Rest assured that there is asecure encrypted connection with a payment server that stores your credit card information.

URL

Make sure that the url address you are looking at has https instead of the http. The s that is added to it means that the webpage that you are visitingis going to be as safe as possible. This is going to be especially true when a person goes to order something from the website. The url address isgoing to work perfectly with the golden lock to make sure that everything that you are doing on the website is secure, including your credit cardnumbers.

Trust

Look for a company that everybody was heard of. These companies are going to have less risk. Think about it – would you rather give your credit cardnumber to Pottery Barn or a random blogger? Furthermore, companies like Pottery Barn are going to be up to date on all of their security software.

Reputation

Make sure you find out how well the company is trusted. Look at the postal address and phone number of the company. If the company does not provide a postal address or a phone number, then this probably means that they do not want to get contacted. Therefore, it is probably a good idea to stay away from buying anything from them. Next, look at reviews on message boards and websites like www.angieslist.com.

Secure Connection

Make sure you are using a secure connection when you are putting any of your personal information into a website. Your connection needs to be protected by SSL. SSL has the ability to break up your personal information, so that no one is going to have the ability to read the information. As long as you have security settings built into your internet browser, it will be able to tell you whether or not the website is secure.

Email Scams

The sixth way is to stay away from signing up for emails. This is because a lot of times, these emails are going to have a way of getting access to all of your personal information, including your credit card numbers. It is very important to remember that a trusted company is never going to ask for your credit card information through an email. Report these emails as soon as possible to a representative from the company, so it can be fixed.

Slow Loading

If it takes more than a few seconds to load your webpage or any email you send out, the average person is going to get aggravated. First impressions are everything, so make sure that whatever platform you use can handle all the content and functions you need.

Sloppy Looks

The second mistake is making a website that is not well organized. Your website should be very easy for any person to navigate. Have a sort of table of contents, but be sure it doesn’t look like a table of contents. Everything anyone wants should be easy to find from the homepage.

Use Search Engines

The third internet marketing mistake is not submitting your website into search engines. This is one of the best ways to find out any information about your website. Find out whatever it takes to get search engines to like your website. There are many strategies to this, but every bit of work you put in could yield countless profits.

Updates

Your website should be updated at least three to four times a week, because the more your website is updated, the more it is going to be able to move up in the rankings of the search engines. Furthermore, if you have a feed, you want people to subscribe, and if you have no updates, they’ll often forget about you and stop following.

Social Networks

The fifth internet marketing mistake you should avoid is not creating a page for your business on social networks. Not doing so is tantamount to throwing money away. In this day and age, social media is where it’s at and where it’s going. Get into all of it – facebook, twitter, pinterest, tumblr, Google+ and more.

Spamming

The sixth internet marketing mistake is spamming your website all over the internet. A company can promote their website without having to spam. If your website looks like it is being spammed, it could get reported and Google will make it much harder to find, perhaps even banned.

Databases

You must keep track of your clients, subscribers, followers, everything! Put it all in one database, so you can communicate and get out deals efficiently. Your customers must feel as though they have a relationship with you, and they won’t feel that way if you only get in touch once a year!

Wrong Promotions

Don’t promote the wrong products. Test out the products yourself and do market research. Find out what’s selling with your competitors. It is very important that your company know what customers want to buy their products and which don’t. The demographics of targeted customers can include sex, age, location, interests, desires, and buying patterns.

No Interaction

The final internet marketing mistake you should know about it a lack of interaction. It is very important that your business have some interaction with your customers, so that your company will know exactly what the customers are looking for. This is one of the best ways to promote your business. Have giveaways for those who complete surveys, always have a way to contact you and always listen!!

Worst Internet Marketing Mistakes You Should Know About is a post from: 4 Rapid Development

PHP has emerged as a very effective and easy to learn technology for developing web applications. This has made it one of the first languages that beginners start working on while learning web development. Mentioned below are 5 tips for such developers who are just beginning with web development using PHP. These tips have been provided by some of the most expert PHP developers.

1. Clear Your OOP Concepts First

For those who are just beginning with web development it is recommended that they first get a thorough knowledge of object-oriented programming and then go into PHP. Those who don’t have a technical background should give some time to learning the principles and clearing their concepts about software development. A beginner should be aware of terms like OOP, design pattern, version control, debugging etc.

2. Use Google Wisely And Extensively

As a beginner you are bound to have many questions (if you don’t have questions then you are not doing it correctly). The good news for you is that you can always find help for all your queries. Make sure that you are connected with a users group as there are such PHP groups all over the world. These are the places where smart men (some might call them geeks) come together to have some meaningful talk, discuss new topics, ideas and provide answers to those who come there with questions. However, make sure that you have Googled your queries before you ask it in the group as they don’t like lazy developers.

3. Get Involved In Open Source Projects

Beginners need to first clear their basic and then join open source projects as they provide access to source code. Further, this will also provide you an opportunity to learn from the top developers and industry specialists. The more you get into the source code, the concepts will get clearer. Once you get expert in PHP you can start providing offshore web development services and make huge profits from it.

4. Find A Mentor

Having a mentor to guide developers in their initial stages is the best thing that can happen to them. They should try to get a mentor who can guide them and talk to them in situations where they get stuck and need guidance. IRC is also a good option but nothing compares with the mentor. Moreover, web developers have entire web in their hand where they can go through thousands of PHP sites and enhance their skills and knowledge through various examples. Don’t expect to be an expert in everything PHP within a fortnight.

5. Study The Code Of PHP Experts

There is nothing better than going through the codes written by industry specialists in PHP. Beginners could learn so much from them that they wouldn’t need anything else. Even if you are an intermediate or advanced developer you should try to study seasoned coders as there is always a better and cleaner way of doing things. Further, try to use reputable libraries wherever possible as their will never be shortage of programming.

Conclusion

If you are a beginner then start with the above tips and soon you will be well versed with web development using PHP.
