Rails Migration

Developing application in Rails is relatively simple because of the available functions offered by the framework. Developers should be able to create online applications to work in many major browsers because of its standardized coding. The only challenging part is to connect the data to Rails in order to create a data intensive application.

Developers who already have online applications or websites can consider transforming their online application into JavaScript or Ajax through rails faster. Because they already have the data, the functions are the only part of the application that should be specified. With the available function in Rails, functions are relatively easier to implement as well.

Working with Migration

An advantage developers can enjoy using Rails is the relative ease of data migration. Transferring data from non-Rails to Rails is faster since Rails provide functions that support migration.

There is actually an option for developers to manually migrate data from non-Rails to Rails. However, there are disadvantages to this technique notably:

• Synchronization with other functions and developers - if the application is built by two or more developers, forcing others to follow a unique coding could take time.
• Challenging updates - when updates are needed in the application, manual data migration have to be checked and often rewritten.

These troubles in data migration can be prevented if the migration procedure offered by Rails will be used.

Using Active Records

The relative ease of Rails in data migration is due to a single technique called Active Record. This technique used by Rails developers will check the data from the old source in order to determine which data are already parts of Rails. Some data may already be a part of the Rails since some functions created by developers may have already migrated some data. Active Record practically sweeps the old source to complete the migration process.

When Active Record determines there are some data that should be migrated to the new application, developers can simply enter the function "rake db:migrate". The data will be immediately migrated to Rails for full implementation in the new Rails application. Aside from completing the migration process Active Record will also update the db/schema.rb which is a file that instructs the application of the database format.

Active Record with a Twist

Active Record is actually the first step offered by Rails. This is where it gets interesting: after migration, developers will practically have little work left so that the Rails-based application will be fully implemented as JavaScript. Rails will keep the arrangement of the data intact so that developers will never have to make some further configurations. This even comes after Active Record worked its raking feature on the database.

The migration feature in Rails is one of the biggest factors that made Rails an easy to use framework. Developers who have been working on transforming their application into Ajax or JavaScript can consider Rails as this allow transformation relatively simpler. Of course, it might require some configurations from the developer's end but it's a lot better compared to building an Ajax based application from the ground up.
