nrdo (NetReach Database Objects) is a database programming tool.
Its primary purpose is to make database programming easier and more convenient. To this end, it performs two separate but related functions:
1) It allows database table definitions to be specified in a source code file. This provides a number of advantages: The files can be maintained in source code control, it is easy to upgrade an old installation to the latest version of the database, and it is possible to include more semantic information than the database itself actually knows. nrdo is invoked at compile time: it reads these table definition (.dfn) files, checks the current state of the database, and performs whatever CREATE or ALTER statements are necessary to make the database match the dfn file.
2) It generates all the repetitive code that is necessary to access the database from a programming language. Current supported output languages are Java and C#, but the language output is generic and new languages are easy to support. Instead of manually creating a database connection, executing an SQL statement, looping over the results and reading the returned data values manually, nrdo generates a class that represents a data row, for each table. It makes use of the extra semantic information in the dfn file to provide functions or methods to retrieve rows of the database by whatever criteria you specify.
