A system provides multidimensional tuple Hilbert ordering within a linear storage structure to enable more consistent and efficient access to stored multidimensional tuples. The database system comprises a tuple storage module that receives multidimensional data elements, where each multidimensional data element is defined by a plurality of different object types, and where each object is associated with a different dimension within a multidimensional data space. The tuple storage module further forms a respective tuple for each of the multidimensional data elements by mapping each object to an associated reference and applies a Hilbert function to the references of each of the tuples to determine a respective Hilbert ordering for each of the tuples. The system further comprises a linear data storage structure that includes a B-tree for storing the Hilbert ordering.

Techniques are described of applying on-line analytical processing (OLAP) to associative databases. For instance, a database adapter implemented in computer hardware or software may automatically create dimensions in a multidimensional dataset for data types in an associative database. The database adapter may then query the associative database for metadata that describes index values of each dimension of the multidimensional dataset. The database adapter may then query the associative database for data values to populate individual cells of the multidimensional database.

A system and method of producing a business report from data contained in a computer based business intelligence system, is provided. The method includes defining one or more macro functions, and producing a report layout containing one or more macrotized database language expressions. The macrotized database language expression having at least one of the macro functions. The method includes produce one or more valid database language expressions for a database query by modifying the one or more macrotized database language expressions in dependence upon the return value of the at least one of the macro functions, and applying the one or more valid database language expressions to one or more database to produce the business report.

An enterprise software system provides dynamic code generation techniques that facilitate quick and efficient resolution of multi-dimensional data demands. The system includes an object store that stores a first object that references multi-dimensional data and an object model that receives a request for multi-dimensional data referenced by the first object. The object model causes the first object to dynamically generate a portion of the executable software instructions for a second object in response to the request and instantiate the second object within the object store. The dynamically generated portion of the instructions enables the second object to calculate a memory address into the multi-dimensional data referenced by the first object. The second object utilizes the dynamically generated portion of the instructions to satisfy the request. Because the second object maintains direct access to the multi-dimensional data, it need not make costly and time consuming function calls to the first object.

A method and system for mapping datasources in a metadata model that provides datasource connections that are structurally isolated from the metadata model and which incorporate physical datasource addressing information for mapping a logical datasource structured within the metadata model to a particular physical datasource “on-the-fly”, and in a run-time environment. In an embodiment of the present invention, security can be implemented to limit user access leveraging an organization's security regime.

A data warehouse solution system comprises a metadata model, a user interface and an engine. The metadata model has an information needs model including metadata regarding information needs for building reports by users, and a data information model including metadata describing data that is available for building reports. The user interface has a customer user interface for presenting the information needs model to the users for report generation, and a modeling user interface for presenting the data information model to the users for manipulating data warehouse objects. The engine has a report management service unit for providing report management service using the information needs model, and a data management service unit for providing data management service including generation of a data warehouse using the data information model.

An enterprise business planning system includes a server to execute an enterprise planning session for a set of enterprise contributors in accordance with an enterprise model, wherein the enterprise model defines hierarchically arranged nodes and associates the enterprise contributors with the nodes. The system further comprises a web browser executing on a remote computing device of one of the enterprise contributors to communicate contribution data between the remote computing device and the server, and an inline compression module executing on the remote computing device. The inline compression module automatically compresses outbound communications from the web browser to the server, and automatically decompresses inbound communication received from the server and forwards the decompressed inbound communications to the web browser.
摘要:
An enterprise planning system accumulates newly submitted planning data in a manner that minimizes database contention, allows ongoing entry of planning data, and allows queries against that data to return consistent results while accumulations are ongoing. An “update process” is the set of activities required to bring the entire data store up to date with a newly submitted value set. The activities may be interleaved with an arbitrary number of other submitted value set changes (other update processes). The enterprise planning system also provides for labeling of consistent sets and removal of obsolete versions of value sets.

A tabular set provider is provided for processing a data agnostic business intelligence query with relational set operations, herein called a relational query against a multidimensional datasource. The tabular set provider comprises a query interceptor, a query decomposer, an OLAP query provider interface, and an operation module. The query interceptor is provided for detecting and intercepting a data agnostic Business intelligence query that has relational set operations that is issued against one or more multidimensional data sources. The query decomposer is provided for decomposing the operands of the set operation in the input query into one or more sub-queries. The OLAP query provider interface is provided for sending the OLAP supported sub-queries to an OLAP query provider and receiving results. The operation module is provided for using set operation functionality provided by a relational query provider that performs the set operations locally on the results of the OLAP data extraction.

An enterprise planning system provides interview-based enterprise planning techniques that enable users to interact with a simple, manageable and understandable front-end for complex planning software. The interview-based enterprise planning system guides users through an enterprise planning process that captures the planning data with a set of ordered input screens that include an interview-based progression of an enterprise planning session. The interview-based enterprise planning system presents an interview-based question and answer planning process in which users enter input data through a combination of, for example, input fields, yes-no answers to interview questions, and drop-down boxes. The interview-based planning process may be customized on an organization wide basis, on a per plan basis, and/or on a per user basis.
