Next-generation Object-Oriented DBMS

Schevo is a next-generation DBMS that focuses on the following:

• Rapid Development.

  It’s easy and fun to create even the most complex of databases. Easily write and understand schema syntax. Quickly place required initial data directly in your schema; use the same syntax to create sets of sample data for development use.

• Rich Schema Definition.

  Write database schemata using concise, easy-to-read Python code. Your schema will describe not only database structure, but also all transactions and rules that ensure database integrity.

• Automated Schema Evolution.

  Deploy a Schevo database and use it to store valuable data, then easily make further changes to the structure of the database. Use Schevo’s tools to help restructure a database and safely migrate data from one schema version to the next.

• Transaction Based.

  Schevo protects your data. Use transactions to make all changes to a Schevo database (it’s the only way it allows you to!), and you can trust Schevo to ensure that your database is left in a consistent state at all times.

• User Interface Generation.

  User interface code takes advantage of the richness of your database schema. Use a full-featured database navigator to interact with your database without writing a single line of code outside your database schema. Build customized UIs using Schevo-aware widgets and UI tools.
