Method and system of unifying data
DCFirst Claim
1. A method using one or more computer systems for querying data relating to an industry having a plurality of industry business context dimensions which define logical groupings of data related to the industry, the data contained in a plurality of data sources, at least one data source having a physical or logical structure differing from at least one other data source, each data source having data which is capable of a logical contextual grouping into at least one data source specific dimension which contains data related to at least one industry business context dimension, each data source having a data access mechanism for facilitating querying thereof, the data sources being part of a system for unifying the data, the system having a plurality of data source query function calls, each query function call querying a single data source regarding a single data source specific dimension, each dimension having at least one dimension instance, the method comprising the steps of:
- receiving from a user the identity of a dimension to be queried;
providing to the user a plurality of data source query function calls from which the user may select at least one data source query function call;
creating a result set having columns defined by the data source query functions selected by the user;
receiving from a user the identity of at least one dimension instance to perform a query regarding; and
populating the columns of the result set with data retrieved from the query.

Abstract
A system, method and database design is provided for unifying data from a plurality of heterogeneous databases, each having business-context related data and a data access mechanism. A database is created (e.g., the UniDimNet) which contains a node for each dimension of an industry. For each data source which is accessible via the system, a set of data source specific dimensions is created and mapped to the corresponding industry business context dimension(s). A set of templates (e.g., UniViews) is created to query the data sources. Each UniView contains a specific question for a specific dimension designed for a specific data source. UniViews query the database they are associated with by using the data access mechanism of the associated database. A central server coordinates the system and facilitates use of the system through an interface (e.g., the UniViewer). The UniViewer allows a user to query the data sources by identifying an industry business context dimension, a dimension instance and at least one UniView. Multiple UniViews can be combined, cached and saved to facilitate complex queries.
