Abstract: PURPOSE: A device and method for processing a relation-filter query language is provided to define new query language and process a query in order to understand and use a query language with respect to a server database and use an Internet technique of the next generation of a web service based on an XML(eXtensible Markup Language). CONSTITUTION: A client application supplies a query language being prepared using an AFQL(Association and Filter Query Language) to a request query creation unit(601). The request query creation unit preprocesses and edits the query language and supplies the query language to a query converter(602). The query language is parsed. A query graph is created from the parsed query language. The query graph is converted into the maximized query graph. The query graph is converted into an actual database language. A schema name and a free ticket among schemata are obtained in a registry. The query language is converted into the optimum query language and supplied to a query execution unit(603-607). The query execution unit refers to a schema name and a free ticket among schemata corresponded to an attribute name of a relation element by corresponding to a DB query language created by the query converter. The query execution unit searches a query DB, reads a corresponding query language search result, and supplies the query language search result to a result creation unit(608). The search result is protocoled and supplied to a result converter(609-610). The result converter converts on object with respect to the query language search result and supplies the query language search result to the client application for enabling the user to display the search result.

Abstract: PURPOSE: A device and a method for converting an ebXML(e-business eXtensible Markup Language) filter query using a G-FQL(Generalized Filter Query Language) are provided to convert the filter query offered from an ebXML registry into an SQL(Structured Query Language) by using the G-FQL defined in the XML sentences. CONSTITUTION: A G-FQL converter converts the ebXML filter query defined by a user into the G-FQL, which is a graph model based query language defined in the XML sentences(10). An XML-object converter converts the G-FQL of the XML sentences into a program object controllable to the user(20). A query graph generator generates a query graph having the same meaning as the G-FQL from the object converted G-FQL(30). An SQL generator generates the SQL by optimizing the query to the query graph(40). A query executer executes the query by using the optimized SQL(50). An object-XML converter converts the object searched by the query executer into the XML again(60).
Abstract translation: 目的：提供使用G-FQL（通用过滤器查询语言）转换ebXML（电子商务可扩展标记语言）过滤器查询的设备和方法，用于将从ebXML注册表提供的过滤器查询转换为SQL（结构化查询 语言）通过使用XML语句中定义的G-FQL。 构成：G-FQL转换器将用户定义的ebXML过滤器查询转换为G-FQL，G-FQL是XML语句（10）中定义的基于图形模型的查询语言。 XML对象转换器将XML语句的G-FQL转换为可控制的用户的程序对象（20）。 查询图生成器生成与对象转换的G-FQL（30）具有与G-FQL相同含义的查询图。 SQL生成器通过将查询优化到查询图（40）来生成SQL。 查询执行器使用优化的SQL（50）执行查询。 对象-MLM转换器将查询执行器搜索的对象再次转换为XML（60）。

Abstract: PURPOSE: A system for a UDDI(Universal Description Discovery Integration) web service registry based on an ebXML(electronic business eXtensible Markup Language) registry and a managing method thereof are provided to save a system construction expense and keep the consistency of information management by using a UDDI service module in a field needing the e-business and a web service. CONSTITUTION: The first client system(10) supports the web service based on the UDDI regulation and transmits/receives a UDDI message. A UDDI registry processes a service request depending on the service request in the UDDI message. The second client system(20) supports the web service based on the ebXML regulation and transmits/receives an ebXML message. The ebXML registry(50) processes the service request depending on the service request in the ebXML message. The UDDI service module(30) converts the UDDI message into the ebXML message and transmits the ebXML message to the ebXML registry.
