Frameworks and Patterns are important instruments that enable the reuse of successful software solutions in recurrent problems. Geographic information systems, on the other hand, are usually designed by people with only little knowledge of database modeling techniques. Therefore, we believe that analysis patterns and conceptual frameworks can both(More)
For its reuse advantages, workflow patterns (e.g., control flow patterns, data patterns, resource patterns) are increasingly attracting the interest of both researchers and vendors. Frequently, business process or workflow models can be assembeled out of a set of recurrent process fragments (or recurrent business functions), each of them having generic(More)
Recently, a variety of workflow patterns has been proposed focusing on specific aspects like control flow, data flow, and resource assignments. Though these patterns are relevant for implementing Business Process Model-ing (BPM) tools and for evaluating the expressiveness of BPM languages, they do not contribute to reduce redundant specifications of(More)
For their reuse advantages, workflow patterns are increasingly attracting the interest of both researchers and vendors. However, actual workflow modeling tools do not provide functionalities that enable users to define , query, and reuse workflow patterns properly. In this paper we gather a set of requirements for process modeling tools that aim to support(More)
Research on workflow activity patterns recently emerged in order to increase the reuse of recurring business functions (e.g., notification, approval, and decision). One important aspect is to identify pattern co-occurrences and to utilize respective information for creating modeling recommendations regarding the most suited activity patterns to be combined(More)
An analysis pattern is any part of a requirement analysis specification that can be reused in the design of other information systems as well. Urban management systems (e.g.: Tax Control Systems, Urban Transportation System) are implemented in a similar way for many counties. This paper proposes three analysis patterns that make possible the reuse of(More)
In this paper, a new algorithm for spatial join operations is introduced. The so-called NRQB (No Replication with Quadtrees and Buckets Spatial Merge Join) enhances the original PBSM by partitioning the space according to the spatial distribution of the objects. In addition, a hash file is created for each input data set and used to enhance both the storage(More)
The need to represent and manage the temporal aspects of the geographic reality has demanded efforts in the geoprocessing area. The complexity of the spatio-temporal information manipulated by a Geographic Information System (GIS) has demanded special efforts for the creation of a conceptual data model able to represent reality phenomena naturally.
