Joomla
Joomla is licensed under GPL, written in PHP and supports SQL databases. The most interesting features of Joomla are blogs, easy search incorporated in the Web site, polls, RSS feeds, easy migration of static Web site to dynamic Web site, site text translation, and adding or extending functions using plug-ins and caching. These features have made Joomla the widely acceptable modular open source development application.  The OpenSource Technogies team been successfully working with Joomla CMS for over two years. Joomla is our showcase and we are Joomla experts. During this time we have successfully completed many complex and simple Joomla projects. We provide Joomla-based services within the spectrum of PHP/Linux-based Web applications. We build comprehensive and robust sites by integrating and customizing Joomla to suit individual client requirements. We can also integrate Joomla with third-party applications such as SAP, Sage and SugarCRM, vBulletin, phpBB among others.
Solutions Keeping Joomla as the base, we customize by integrating components and plug-ins for complex needs. Joomla development solutions include:
- Community Portals:
We use Joomla's community-builder extension suite to develop community Web sites for our clients. These enable administrators to maintain and manage their online user communities and capture customized user information during registration. Front-end users can create profiles, upload them to the Web site and browse through other user profiles.
- Online Shopping Applications:
VirtueMart is one of the more popular shopping cart components available with Joomla. The shopping cart solutions developed by us provide the clients with robust applications that enable them to easily operate their storefront. Administrators can maintain and manage detailed product catalogs and track and process online orders. We can also include search options for customers to browse through products and book orders online.
- Online Image Galleries:
We develop these through the Image Gallery component of Joomla. Users can upload and add images to galleries in several categories. The front-end users browse through the galleries, rate and post comments about the images.
- Site Maps:
Joomla's indexing component of Joomla can develop and integrate extensive site maps, content indexes and visual maps. This enables our clients to showcase visual maps on their Web site. Administrators can define specific areas within the map that users can enlarge.
- Corporate Web sites:
have developed many Web sites for corporate clients which include an online platform about their services and products. These dynamic Joomla-based Web sites provide clients with an automated system to publish and manage content appearing on the Web site.
- Online Magazines:
Joomla allows publishers to easily upload and showcase online available articles from their offline magazines. We have integrated several components such as the subscription manager to enable Web site users to send in their subscriptions for the offline edition of the magazine. This provides publishers with an easy and effective mechanism to increase the subscriber base through increased subscriptions.
- Micro-site Management:
This enables client to offer their various business customers the option to register with them and create their individual micro-sites to advertise their services. Buyers can search and browse through the micro-sites and send in their queries.

Wordpress
WordPress started in 2003 with a single bit of code to
enhance the typography of everyday writing and with fewer users than you
can count on your fingers and toes. Since then it has grown to be the
largest self-hosted blogging tool in the world, used on millions of
sites and seen by tens of millions of people every day.

Everything you see here, from the documentation to the code itself, was created by and for the community. WordPress is an Open Source
project, which means there are hundreds of people all over the world
working on it. (More than most commercial platforms.) It also means you
are free to use it for anything from your cat’s home page to a Fortune 500 web site without paying anyone a license fee and a number of other important freedoms.
About WordPress.org
On this site you can download and install a software script called WordPress. To do this you need a web host who meets the minimum requirements and a little time. WordPress is completely customizable and can be used for almost anything. There is also a service called WordPress.com
which lets you get started with a new and free WordPress-based blog in
seconds, but varies in several ways and is less flexible than the
WordPress you download and install yourself.
CQ5
CQ5 Web Content Management (WCM) is a platform for delivering engaging, multi-channel customer experiences to drive online business success.
