Rails

Rails is a development framework for Web-based applications, including those that access databases. Due to the intimate connection with Ruby, it is often called Ruby on Rails or RoR.

Rails was developed by David Heinemeier Hansson in early 2000 and was released in 2004.

A significant and characterizing part of Rails is its approach to connectiong object-oriented software with a relational database.

What are thumbs up and downs for ROR

Strengths

• Convention over configuration
• Active record
• Metaprogramming
• Scaffolding
• Built in testing

Limitations

• As pointed out by (Tate and Hibbs, 2006) Rails has poor support for object-relational mapping (ORM) for legacy schemas compared to Java's approach.
• Assuming a single, non-compund primary key for the database and not supporting compund primary keys for the database is anotherlimitation highlighted by Monson-Haefel(2006).
