From GeoStore to GeoToolKit: The Second Step - Balovnev, Breunig, Cremers (1997) (3 citations) (Correct)
....Todays geo information systems are closed systems mainlysupporting geographic tasks in 2D space. In new spatial application areas such as environmental research, geology, city planning or telecommunications, however, a database and processing support for 3D 4D objects is required [Rap89] MJ94] Wor94] Bre96] Thus the development of object oriented 3D 4D modelling and data handling components for geo information systems is a new challenge for the spatial database community. To our knowledge, there are no comprehensive experiences with the management of 3D 4D data in ODBMS. Since ....

Managing Multiple Representations of Georeferenced Elements - Medeiros, Bellosta, Jomier (1996) (1 citation) Self-citation (Medeiros Jomier) (Correct)
....representations can be compared to views, while materialized representations may be treated as versions (of real world geographic elements) Our solution combines both versions and views, thereby facilitating the joint management of both types of representation. It extends the gis related work of [18, 19], presenting and detailing a framework which allows the management of multiple representations through versions and views. This solution is based on the dbv version approach [3] 9] Versions are a means of storing different states of a given entity, thereby allowing the control of alternatives ....
....manage efficiently as many DBVs as needed. Such a multiversion database enables the simultaneous management of distinct alternative scenarios, as well as handling georeferenced feature evolution through time. It can be used to handle some aspects of multiple representations (notably through time [19]) In the upper part of Figure 1, the multiversion database is composed of four database versions : Dv 2 is derived from Dv 1 by versioning the schema; Dv 3 is derived from Dv 2 by versioning the data. 5 Support of multiple representations in GIS The use of views to support multiple ....

An Extensible Framework for Spatio-Temporal Database.. - Faria, Medeiros.. (1998) (1 citation) Self-citation (Medeiros) (Correct)
.... Reported prototypes are usually restricted to only one dimension that is, dealing with temporal database management or with spatial database management, but not both (e.g. GR93, SV92, AS91, SK96] At most, the handling of time in a spatial context is limited to version management (e.g. MJ94, AW96] or restricted to a limited set of operations [SW95] The difficulties in implementing a spatio temporal system are due to the new problems that are encountered when combining the problems found for handling each dimension. First, there is the issue of defining a minimal set of operators ....
