Whenever you are working with large or small datasets, file geodatabases optimized for use in ArcGIS are ideal for storing and managing geospatial data. File geodatabases offer structural, performance, and data management advantages over personal geodatabases and shapefiles.

With a geodatabase, all an organization՚s GIS data can be stored in a central location and in a uniform format for easy access and management. The geodatabase can be scaled to suit a single-user or multiuser access and editing environment.

Advantages of Geodatabase

The main advantages of the Geodatabase topology are:

  • The topology structure is not explicitly stored.
  • The user decides which topology rules are important for his dataset.
  • The user must specify the conditions of the dataset.
  • The user decides what should happen with spatial objects if they do not meet all the conditions.
  • Topological errors are not solved automatically, but the user must solve errors manually.
  • The validation process is relatively short.
  • It should be noted that with this validation, only the errors are marked, not solved.
  • After editing some objects in the geodatabase, not the entire dataset has to be validated again.
  • The edited area is marked as a dirty area and only the dirty areas must be validated again.
  • The Geodatabase topology is easy to use.
  • You do not need to have special knowledge about topology to create a set of logical conditions for the data.
  • The wizard to implement the topological rules is very useful and straightforward.
