GIS topology can be explained as the spatial relationships between connecting or adjacent vector features (points, polylines and polygons) in terms of having a better accurately and precisely geometric data structure model. GIS topological network might be carried out solving various GIS problems such as improving GIS digitizing errors especially during processing the vector data. Additionally, GIS topology is essential phenomena for performing different types of spatial analysis as network analysis. Within the scope of DBMS (Data Base Management System), the topological network model manages spatial relationships by illustrating shapes as the graph of topological instruments (nodes, faces, and edges) via computer geometry. In this study, the performance of different GIS topological network applications is analyzed in terms of time and space complexity.
