摘要:
A system for enterprise information integration is described. The system is based on different layers: the data sources, source ontologies corresponding to the data schema of the data sources, an integration ontology integrating the different source ontologies, a level of query input, preferably in the form of a web service. Between the levels, mapping rules are used. For the mapping of document style web services and XML documents to ontologies detailed rules are given, covering i.a. simpleContent and complexContent elements, which are mapped to class properties and relations (object properties), respectively.

A system for enterprise information integration is described. The system is based on different layers: the data sources, source ontologies corresponding to the data schema of the data sources, an integration ontology integrating the different source ontologies, a level of query input, preferably in the form of a web service. Between the levels, mapping rules are used. These mapping rules and the entire system are based on predicate logic. The queries are answered with the help of the rules using inference based on predicate logic.

The invention relates to a method for searching within elements of a hierarchically structured database (10), wherein each element has one or more hierarchically structured nodes for defining attributes of said element and wherein one or more nodes of the searched element must fulfill one or more search conditions (c0,ci, . . . ) the method comprising the steps of a. selecting a plurality of nodes and assigning a unique identifier (EID) to each of the selected nodes; b. creating a reference index (20), that allows to derive for each unique identifier (EID) of a selected node the corresponding element of the database (10); c. for each of the one or more search conditions (c0,ci, . . . ): retrieving a set (L, Ei) of unique identifiers for ancestor nodes of nodes, which fulfill the respective search condition (c0,ci, . . . ); d. intersecting the sets (L, Ei) to obtain a final set (L) of unique identifiers; and e. retrieving the searched elements of the database (10) based on the final set (L) of unique identifiers (EID) and the reference index (20).

摘要:
Monitoring a software system based on a service oriented architecture (SOA). The method may involve system components communicating with each other via sending messages. The method may include receiving a monitoring message by a monitoring component where the monitoring message may be sent from a system component of the software system. The method may further include providing an ontology including at least one interpretation rule for the message by the monitoring component. The method may also include reacting of the monitoring component in accordance with the at least one interpretation rule.

Managing the lifecycle of a service oriented architecture (SOA). The method may include selecting a subset of a plurality of objects of the SOA for lifecycle management in accordance with the requirements of an organization implementing the SOA, and assigning a lifecycle property to each member of the subset of the plurality of objects of the SOA.
摘要:
The present invention concerns an analysis system (1) for analyzing at least one continuous query (100) for at least one input data stream (200), wherein the at least one input data stream (200) comprises a sequence of events captured by at least one sensor and wherein the debugging system comprises:a. an analyzer (10), adapted for executing the at least one continuous query (100) and at least one modified continuous query (100′) on the at least one input data stream (200), for comparing at least one output data stream (300) produced by the at least one continuous query (100) with at least one second output data stream (300′) produced by the at least one modified continuous query (100′) and for indicating at least one difference between the at least one output data stream (300) and the at least one second output data stream (300′);b. wherein the analyzer (10) is adapted for synchronizing the execution of the at least one continuous query (100) and the at least one modified continuous query (100′).
摘要:
A method for the consistent control of policies assigned to objects of a service oriented architecture is disclosed. Each policy may include one or more assertions, and the method may include identifying one or more operational dependencies between at least two SOA objects, analyzing the assigned policies of the at least two SOA objects to determine any inconsistency, and issuing a warning to a user if an inconsistency has been determined.
摘要:
Runtime execution of one or more tasks defined in a workflow process language. The method may include obtaining a description of the task from a process ontology (PO). The PO may define a hierarchical taxonomy of executable tasks, where each task refers to at least one frame of a hierarchical frame taxonomy of the PO. The method may further include identifying at least one parameter as described in the frame description to which the task refers, resolving the value of the at least one parameter, and executing the most specific applicable version of the task contained in the task taxonomy of the process ontology.
摘要:
A database system comprising a database logic adapted to perform database processing and a backup interface for external backup, wherein the backup interface is adapted to connect the database sys-tem to a plurality of different external backup systems and wherein the backup interface is adapted to receive one or more plugged-in functions of the different external backup systems. The database logic communicates with the backup interface using only a predefined set of extension points, at least some of the extension points being adapted for being implemented by one or more of the plugged-in functions of each of the different external backup systems.
