### CrossLogic Objects for Mapping**

CrossLogic Objects for Mapping (OfM) provides a framework that turns your RDBMS into an ODBMS. With OfM you can map complex (thick) class hierarchies to relational data sources, (ODBC and native DB2). Objects can be rendered from multiple rows and tables while maintaining full object identity. Persistent Classes defined using OfM are created just like any Smalltalk class. Mapping can occur at any time, and does not require special getter/setter methods to be defined.

#### Highlights

OfM is more than an Application Programming Interface (API) wrapper for RDBMS. OfM also:

- Protects your investment in Object Technologies by providing object identity. Application programmers work with objects, not strings from database rows
- Eliminates your need for additional Object Technology RDBMS application development tools by providing advanced support for

- Concurrency
- Object mapping for joined tables
- Object mapping across multiple tables
- Object Cache

- Increases your productivity by providing type transformation between Smalltalk objects and RDBMS data
- Increases your productivity by providing both a Smalltalk Application Programming Interface Framework and visual tools to define and map objects to an RDBMS
- Increases the value of your OfM Framework by working with other data sources
  - Extendible framework to non-relational data sources, (APPC,TCPIP, etc..)
  - Works with multiple database systems.
