Schemaform is a high-level database programming DSL for Ruby, intended to greatly reduce the work needed to produce a performant back-end from a complex, normalized design. In simple terms, it provides the power of spreadsheets in a relational context. With Schemaform, you can:

• capture even your most complex structures, relationships, and processing quickly and concisely
• leave all the denormalization and performance-related tuning to the system
• never compose another line of SQL
• focus instead on making your software great.

Schemaform does for you the very work you would normally have to do by hand and intuition when taking a database-driven system from design to implementation.
