The information contents of the output message of the selected source are transmitted as an asynchronous communication to the application of the wireless device identified by the correlation ID.

A method of automatically matching schemas begins by extracting schemas from sources and targets. Then, source and target attributes are extracted from the schemas. Each source schema will have multiple source attributes and each target schema will also have multiple target attributes. The source attributes and the target attributes are presented as nodes in a bipartite graph. This bipartite graph has edges between nodes that are related to each other. A plurality of similarity scores are defined between each set of related nodes. Each of the similarity scores is based on a different context-specific cue of the attributes that the nodes represent. These context-specific cues can comprise lexical name, semantic name, type, structure, functional mappings, etc. An overall weight is computed for each edge in the bipartite graph by combining the similarity scores of each set of nodes that form an edge. In addition, an optimal matching of the schemas is assembled, so as to indicate the level of similarity between each of the source and target schemas. The optimal matching selects pairs of nodes between source and target schemas that maximizes the number of nodes matched as well as the overall score of match for the nodes selected.

The disclosed mapping techniques ensure that (i) one or more source documents that conform to one or more of the source schemas can be recovered from one or more target documents that conform to the at least one target schema, if a mapping exists between the one or more of the source schemas and the at least one target schema; (ii) queries on one or more source documents that conform to one or more of the source schemas in a given query language can be answered on one or more target documents that conform to the at least one target schema; and (iii) the one or more target documents conform to a target schema.

Schema conversion approaches convert images of complex objects. The schema conversion is performed on images of complex objects belonging to a root class, whether those objects are instances of the root class or instances of a subclass of the root class. A complex object is an object that is comprised of a collection of objects or that has another object as an attribute. The approaches use change vectors to represent changes to make to an image to convert it between the target schema version and source schema version. Change vectors are generated based on schema version records, each of which describes the properties of a schema version, including the attributes in the schema version and the data type of each of the attributes. The approaches evolve changes that includes addition, modification and deletion of object attributes. They convert from an earlier schema version to a later schema version, and vice versa, i.e. from a later schema version to a earlier schema version.

A computerized method, program product, and a service that discovers trace data inserted into a source database having an unknown schema. Once the trace data is found by a dynamic data discovery engine, the tables, the fields, and the attributes of the fields in the source schema in which the trace data were located can be evaluated to determine if the data in the fields are pertinent to a target database. If so, then the data in those fields can be mapped and transferred to a target database. The dynamic data discovery engine generates the commands in both the source and the target database command language to find all pertinent data, map and transfer the data from the source database to a target database. The dynamic data discovery engine generates commands to create the target database and/or fields within an existing target database for the mapped and transferred data.

Systems and methods for developing a data repository containing property listing information automatically acquired from a plurality of multiple listing services (MLSs). The property listing information from various MLSs can be mapped to a common representation and stored in the data repository. The invention utilizes and transforms information from different source MLSs which may have a particular data schema that may or may not match a predetermined common schema for the data repository. The listing information is thus consolidated from MLSs even when their schema may be different from each another or the predetermined data repository schema. The data repository schema may be selected such that each of the fields that comprise the source MLS property listing information in its native schema (and all its elements including but not limited to, agent rosters, office rosters, and tax data) can be mapped from the source schema to the data repository schema (the destination). Accordingly, the data of the source property listing from various MLSs can be preserved. Possible mappings include one-to-one, one-to-many, many-to-one and others. For certain applications of the invention, mappings may be direct where the listing information data from an MLS is simply copied as is, or it can undergo a data transformation process that is based on a predetermined set of listing field mapping rules.

The present invention creates a model that maps object classes in an object-oriented environment to a data source. The model maps the relationship between properties of each object class and data of the data source. The present invention can be used with a data source such as a relational database, user interface, file system, or object-oriented database. An application's object classes and data source schema are designed independent of the other since the model can be used to map one to the other. The model is comprised of entities and attributes. An entity maps to an object class and to at least one table of the DBMS. An entity contains attributes either simple or derived. A simple attribute maps to a DBMS column. A derived attribute is a combination of other attributes and does not directly map to a DBMS column. A relationship creates a link between entities of the model. A relationship can be used to flatten an attribute or flatten a relationship. A flattened attribute is an attribute of one entity that is added to another entity. A flattened relationship is created by the elimination of intermediate relationships between two entities. Relationships can be either unidirectional or bi-directional. A unidirectional relationship has a single traversal path that has a source entity and a destination. A bi-directional relationship has two traversal paths. A reflexive relationship can be created using a single entity. The model is used to synchronize object properties and the data of the data source.

Mapping of data source schema data types relating a server side database description into a set of OLE DB data types is rendered subject to user modification by provision of a dual Schema File at a client side terminal which contains an original unmodifiable copy and a modifiable working copy of the data source schema. When the server side database description is altered, user modifications to the modifiable copy are preserved as much as possible by performing a matching process on the client side in the course of generating new unmodifiable and modifiable schema files which comprise a new dual Schema File.

A value field index for data stored in a data source is generated by analyzing a data source schema, analyzing intended queries of the data and analyzing the data. Problematic queries are identified and token fields are designated. The value field indexes are then created using the data source schema; and the value indexes are embedded in other indexes.
