Certain example embodiments relate to a database index for indexing one or more text documents in a database. The text documents include one or more hierarchical nodes, and each node includes one or more words. The database index includes at least one entry, with each entry including a key. The key, in turn, includes a subset of words occurring in one of the hierarchical nodes of the text documents and the name of the respective hierarchical node. Associated with each key is a value including one or more references to the text documents in which the subset of words occurs.

Database index and database for indexing text documents

The present invention concerns an XML data base management system (XDBMS,) for an XML database () comprising XML documents (), each XML document () comprising one or more structural elements () and adhering to an XML schema (), wherein at least one of the structural elements () is protected against access of a user (), the XDBMS () comprising:

XML database management system for an XML database comprising access-protected XML data

Searching within elements of a hierarchically structured database. Each element may include one or more hierarchically structured nodes for defining attributes of the element. One or more nodes of the searched element may fulfill one or more search conditions (c,c, . . ). A plurality of codes may be searched and a unique identifier (EID) may be assigned to each of the selected nodes. A reference index may be created that allows to derive for each unique identifier (EID) of a selected node the corresponding element of the database. A set (L, E) of unique identifiers may be retrieved for each of the one or more search conditions for ancestor nodes, which fulfill the respective search condition. A final set of unique identifiers may be obtained. The searched elements of the database may be retrieved based on the final set of unique identifiers and the reference index.

Method for searching within elements in a hierarchically structured database

A system for enterprise information integration is described. The system is based on different layers: 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.

Enterprise information integration platform

A method for storing and managing data on a storage medium connected to a computer system, wherein the data consists of a plurality of data elements and a plurality of tags, wherein each of the data elements is assigned one of the tags to form a plurality of pairs each consisting of at least one of the data elements and one of the tags, wherein each of the pairs is assigned a position in a hierarchical structure, wherein each of the pairs is stored and managed on the storage medium together with a pair-individual hierarchy indicator indicating the position of the pair in the hierarchical structure. Furthermore, a computer program for carrying out this method and a data carrier storing such a program are provided.
