Rails is an ideal solution if you are going to build any of the following types of website:

1. CONTENT MANAGEMENT. If the purpose of your site is to present thousands of articles, audio files, or other database-friendly content, Rails is a great solution because of the ease with which users will be able to navigate the site, and the ease with which you will be able to upload and manage the content.
2. CUSTOM DATABASE SOLUTIONS. More and more of our new projects are custom solutions requiring a novel database structure to support a creative new business model. In most cases, Rails is an ideal way to realize build these solutions at a fraction of the usual time and expense.
3. MEMBERSHIP SITES. Membership and social networking options are pretty much “baked” into Rails. A variety of plugins are available to solve just about any social networking challenge you can think of.
4. E-COMMERCE. Most e-commerce sites benefit tremendously from Rails’ user-friendly features and modular approach to site development. We can also include features that you would normally only find in high-end e-commerce suites, such as bulk uploads and updates (for product descriptions and photos, extremely handy when you have thousands of products), custom pricing algorithms, and on-the-fly photo resizing/cropping (especially handy for making product thumbnails for browse pages).
