In an embodiment, a method of computer program compilation is presented. In this method, a compiler for a first programming language is provided. In one example, the first programming language allows a data assignment to depend on a result of a previous data assignment. Source code including a first portion written in the first programming language and a second portion written in a second programming language is accessed, with the second portion representing a data transformation from a first data structure accessible in the first portion to a second data structure accessible in the first portion. In one example, the second programming language prevents a data assignment that depends on a result of a previous data assignment. The source code is compiled using the compiler to generate executable code to be executed by an engine for the first programming language, which includes an interpretation engine to interpret the second portion.

Methods and systems of monitoring events occurring in a computer system are provided. An event monitoring instruction including a condition is parsed, the event monitoring instruction expressed using syntax defined in source code, the parsing resulting in an event channel to monitor and the condition. Then execution of an application is paused. The event channel is monitored until an event occurs on the event channel. Then an event handler for the event is run in response to the event occurring on the event channel. The condition is evaluated to determine whether the condition is satisfied. Execution of the application is resumed in response to the condition being satisfied.

A method is described that comprises receiving at a first interface a request to lock a row of data from a database table. The method also comprises formatting the request into a format suitable for reception by a second interface. The second interface is an interface to a logical locking function.

A system and method are described for performing a mapping between persistent data objects and a database. For example, a method according to one embodiment of the invention comprises determining whether an attribute having a generic type is an instance of a persistent class; and if the attribute is an instance of a persistent class, then mapping the attribute to a discriminator column holding the type associated with the attribute and further mapping the attribute to a reference column holding a key associated with the attribute.

Object-relational mapping system and method for generic relationships

An application system includes a first process configured to execute an application program, wherein the application program is operable to use a set of data structures. The application system also includes a second process configured to interpret a markup language document. A transformation template is configured to specify a symmetric mapping between the markup language document and the set of data structures. A transformation virtual machine runs in association with the first process and is operable to execute the transformation template. The transformation virtual machine is operable to perform a symmetric transformation between the markup language document and the set of data structures to allow the first process and the second process to exchange information.

Logically locking in a Java Data Object rather than in a transactional context of a data store to separate the process of isolating an object from accessing a data store to which the object is mapped.
