This invention is directed to relational extenders for a computer-based relational database. Each relational extender includes at least one column, in a first, business table containing a user defined application database, dedicated to object handles for defining the complex data type of an object; a second, attribute, table containing at least one column defining a unique characteristic associated with the one object and one column dedicated to containing the object handle; and a third, metadata, table containing at least one column defining a common characteristic associated with all objects defined within the business table and one column dedicated to containing the object handles and at least one column dedicated to containing a reference to object data associated with the object. The relational extender further includes a fourth table containing a reference to each object handle column defined in the first table, and a fifth table containing the names of the second and third tables for each object defined in the first table.

A data processing system having a main processor and a coprocessor. The main processor responsds to coprocessor instructions within its instruction stream by issuing the coprocessor instructions upon a coprocessor bus and detecting if the coprocessor accepts them by returning an accept signal. The coprocessor instructions include a coprocessor number and the coprocessor checks this number to see if it matches its own number(s) to determine whether or not it should accept the coprocessor instruction. A data type field within the coprocessor number in the coprocessor instruction also serves to specify one of multiple data types to be used in the coprocessor operation; particular coprocessors can interpret this part of the coprocessor number to determine data type. If the coprocessor supports multiple data types, then it has multiple coprocessor numbers for which it will issue accept signals and then uses the data type field to control the data type used. If a coprocessor does not support a particular data type then it will not issue an accept signal for coprocessor instructions that specify that data type. The main processor can then use emulation code to provide support for that coprocessor instruction.

Methods, systems, and computer program products for programmatically serializing complex objects (such as JavaBeans(TM)). In contrast to prior art techniques, a manually-specified data type mapping specification is not required as input to the serialization process. Instead, the present invention programmatically generates this type mapping, responsive to encountering run-time exceptions during the serialization process. The serialization process is therefore "self-healing". This approach is especially advantageous when serializing complex objects that may include complex data types and/or embedded objects. The programmatically-generated type mapping information is preferably used to generate a serialized version of the complex object, and can also be used during deserialization. In addition to improving serialization techniques, this type mapping information facilitates dynamic integration and transformation of data between heterogeneous formats.

A framework for extending the capabilities of an event processing system using one or more plug-in components referred to herein as data cartridges. In one set of embodiments, the data cartridge framework described herein can enable an event processing system to support one or more extension languages that are distinct from the native event processing language supported by the system. For example, certain “extension language” data cartridges can be provided that enable an event processing system to support complex data types and associated methods/operations that are common in object-oriented languages, but are not common in event processing languages. In these embodiments, an event processing system can access an extension language data cartridge to compile and execute queries that are written using a combination of the system's native event processing language and the extension language.

Conceptual Process Redactor (CPR) is a method and system, for describing and translating conceptual descriptions of objects and their methods to OOPS object layouts and methods. CPR utilizes conceptual structures (C-structures or CPR classes), to describe information. C-structures are hierarchical information structures, and each hierarchical path is considered as a CPR data type. Thus, instead describing data in terms of OOPS data types, which are bound to storage layouts of the underlying machines, CPR describes data in terms of CPR data types, which may be regarded as concepts. The CPR translator, translates the CPR data types to their Oops equivalents by making use of Type Translation library, supplied with the CPR class description. CPR data types are unique within the class they are defined, and hence serve to identify the field as well describe a data type. Thus, a typical usage like Part quantity field of sales order header is now a data type in its own right, as well as a field. The uniqueness of the CPR data types is made use of in identifying the parameters of a method, if the context in which the method is invoked in known a priori. The CPR system provides a mechanism, called collaboration, to conceptualize process descriptions. As per collaboration, a group of objects may collaborate to accomplish a particular task (method). The collaboration serves as a context, and hence method invocations in CPR may omit the parameters, and these are identified from the collaboration. Each object acts as a client and the rest of the objects and temporary variables, act as servers. The client/server relationship is made use of by process descriptions called CPR Interface groups, which are specified for each of the collaboration objects, participating in the collaboration. In addition, to the intra object client/server relationship, objects are broadly classified as data sources or data containers, where the first form is considered as a sequential representation of data, and the latter form is considered as a random representation of data. Each data source may be grouped with zero or more data containers, and each such group is called a collaboration group. One or more collaboration groups may be specified in a table called the collaboration table, and collaboration groups with sequential group numbers are considered as a logical unit of execution. Thus, collaboration groups and the associated client/server relationship between the objects in the collaboration groups, may be used to conceptualize fairly complex method descriptions. The CPR translator will translate the process descriptions specified as CPR Interface groups for the collaboration objects into oops methods. The CPR runtime system provides necessary support to access/update the collaboration objects, and to invoke the oops methods generated during translation.

Disclosed is a method of identifying data format information. A regular expression described in schema is matched with data sub-formats. From the matching, a ‘type’ of the regular expression is then identified. More specifically, a regular expression tree is constructed (5001) from the regular expression. At least one sub-format of the data format is then identified, the sub-format comprising at least one constituent part. Each constituent part of each sub-format is represented (5002) with a corresponding Finite State Machine, each Finite State Machine comprising an entry point, an exit point and at least one state. The regular expression tree is then matched (5003, 5004) against the Finite State Machines to identify a matching one of the, sub-formats, the one sub-format thereby representing the data format of the regular expression.
