5.0 |
| Description: |
Open source object-relational mapper and code generator.
OR.NET generates a data access layer in stand-alone C# 2.0 after scanning your database’s meta-data.
Features include:
- Creates all relationships based on both simple foreign keys, and many-to-many mapping tables. All identity columns will be found, and treated appropriately for inserts, and all nullable fields will be created as nullable properties in code.
- Transparently manages all foreign key relationships, and many-to-many relationships for you.
- In addition to automatic class structure generation, you can also manually create and modify classes by specifying which columns represents the key, which columns to create properties out of, and which other objects the new class links to, either through a foreign key, or a many-to-many mapping table – all through a GUI.
- The classes generated are database independent, with all data-access happening through generated assembler classes.
- All SQL commands are fully parameterized, and therefore resistant to injection attacks, and also slightly better performing due to SQL Server’s caching of execution plans. |
