Abstract
One embodiment of the invention employs techniques for providing a default object-relational mapping between persistent data objects (i.e., the objects that represent persistent data from a database) and a relational database. In a Java environment, for example, each entity bean is mapped to a particular database table, and each of the persistent fields within the entity bean are mapped to columns of the database table. Relationships between entity beans are expressed as mappings between primary keys and foreign keys within the database schema. Dependent-value persistent fields may be mapped to multiple columns or to a single column of a special Java type (java.sql.Types. BLOB). In addition, one embodiment of the invention generates a default database schema using the default O/R mapping by executing a series of SQL commands generating the tables and columns.
