Magento Introduction and advantages

Magento

  Magento was first launched on March 31, 2008. It was developed by Varien (now Magento Inc) with help from the programmers within the open source community but is owned solely by Magento Inc.. Magento was built using the Zend Framework.It uses the entity-attribute-value (EAV) database model to store data. It should seprated into three types (Magento Enterprise Edition , Magento Community Edition , Magento Professional Edition),Mainly all magento users used MEE and MCE

Magento Enterprise Vs Community

There are currently two editions of Magento available, Magento Enterprise Edition and Magento Community Edition. Both editions of Magento are valuable, however, they are meant for different audiences. You might have questions about what the two editions are, why both editions need to exist and what the differences between them are. This FAQ will help you get answers to these questions and set you on the right path for eCommerce success.

Magento Enterprise Edition :

MEE is the complete eCommerce solution for businesses that are ready to take full advantage of their online channel. This solution combines an unrivaled feature set with world-class support and virtually infinite flexibility, at a fraction of the price charged by competitive platforms.for MEE Magento provide technical support.

Magento Community Edition :

Development of the MCE continues at a rapid pace through this model, providing a basic and powerful solution for small shops looking for a state-of-the-art eCommerce platform.Magento Community Edition is open source software and can be downloaded for free.

Developers can modify the core code and add features and functionality by installing extensions from the Magento Connect marketplace. MCE to run their stores will want to have access to their own Magento experts, since Magento does not provide technical support for this software.

Additional Modules :

There are some interesting additional modules in the Enterprise Edition:

• Private sales, which allows retailers to restrict access to stores and offers to selected customers, and to manage the launch and termination of private sales.
• Access to the back-end can be controlled at the website or store level, where in the Community Edition you can only restrict access at the function / module level. This is very useful for multi-store Magento installations.
• The ability to merge and combine content from one store with another, and to use this facility to create a content staging environment. Instead of having 2 instances of Magento (as we do with some clients at present) one for the next catalog, one for the current catalog, you could do all this in one installation, which is a very interesting development, especially for larger retailers. A full audit trail of all admin actions. Very useful.

Just use a onchnage Event for select box.

<select id="selectbox" name="" onchange="javascript:location.href = this.value;">
    <option value="https://www.yahoo.com/" selected>Option1</option>
    <option value="https://www.google.co.in/">Option2</option>
    <option value="https://www.gmail.com/">Option3</option>

</select>

And if selected option to be loaded at the page load then add some javascript code

<script type="text/javascript">
    window.onload = function(){
        location.href=document.getElementById("selectbox").value;
    }       
</script>

for jQuery: Remove the onchange event from <select> tag

jQuery(function () {
    // remove the below comment in case you need chnage on document ready
    // location.href=jQuery("#selectbox").val(); 
    jQuery("#selectbox").change(function () {
        location.href = jQuery(this).val();
    })
})
