Using GXL for exchanging business process models

Andreas Winter, Carlo Simon
2005 Information Systems and E-Business Management  
This is done by exchanging both, the instance graph, representing the data itself, and the schema, representing the graph structure. Business process models are usually depicted in a graph-like form.  ...  The GXL Graph eXchange Language is an XML-based standard exchange language for sharing graph data between tools. GXL can be customized to exchange application specific types of graphs.  ...  Fig. 3 3 GXL representation ofFigure 2 Fig. 4 4 Graph schema Fig. 5 5 Graph schema represented as Graph Fig. 6 6 GXL representation of schema graph inFigure 5(extract) Fig. 8 8 GXL schema for event-driven  ...

Automatic validation of requirements to support multidimensional design

Oscar Romero, Alberto Abelló
2010 Data & Knowledge Engineering  
As discussed in the literature [24, 36] , the ideal scenario for deriving the data warehouse conceptual schema would consist of a hybrid approach (i.e., a combination of data-driven and requirement-driven  ...  Most current methods follow either a data-driven or requirement-driven paradigm and only a few use a hybrid approach.  ...  As such, this method cannot handle denormalized schemas or requirements. • Phipps and Davis [28] proposed a supply-driven method that is validated a posteriori by a demand-driven stage.  ...

A Conceptual Query-Driven Design Framework For Data Warehouse

Resmi Nair, Campbell Wilson, Bala Srinivasan
2007 Zenodo  
Exploiting the nature of queries, in this paper we propose a query driven design framework. The proposed framework is general and allows a designer to generate a schema based on a set of queries.  ...  Data warehouse is a dedicated database used for querying and reporting. Queries in this environment show special characteristics such as multidimensionality and aggregation.  ...  As we mentioned earlier, the intermediate schema is a graph; so the derivation of the data warehouse schema is suggested as a graph reduction process.  ...

Multidimensional Design by Examples [chapter]

Oscar Romero, Alberto Abelló
2006 Lecture Notes in Computer Science  
If no multidimensional schema is generated for a query, we can state that requirement is not multidimensional.  ...  In this paper we present a method to validate user multidimensional requirements expressed in terms of SQL queries.  ...  Our aim is to label each node as a Cell (factual data) or a Level (dimensional data). A correct labeling of all the nodes gives rise to a multidimensional schema fitting the input query.  ...
