Build Geodatabase

Hi

Im kinda new at this

I'm just trying to get a start on a project and was wondering if anyone had some suggestions. I have to build a geodatabase prototype using a Single Line Street Network(shapefile). I also have hydrological networks and a path network to work with as well. My focus needs to be on what attributes and topological structures (or other database transaction rules) would be needed to be added or modified from the existing data. I need to determine relevant issues for the migration of this dataset to a new format. (spatial data representation and modelling??)

Are there any suggestions?

It depends really on what you are going to do with the data you have. You can use Network Analyst extension for routing with your streets and path layer. Then you have to learn about network datasets and how to prepare data for those.

Prepare data for use with the Network Analyst extension:

Design the network dataset:

You can use Geometric Networks based on your hydrology data:

Topology policies would be relevant for both of those parts:
Topology basics:

If you have time, I encourage you to check a very good book on geodatabase modelling:
Modeling Our World, Second Edition: The Esri Guide to Geodatabase Concepts
http://esripress.esri.com/display/index.cfm?fuseaction=display&websiteID=178&moduleID=0

If you want to take a look at the existing data models, Esri and Esri's user community have prepared quite a few geodatabase models which are available for download. Depending on how well they suit you, you might need to adjust the database structure, tables, etc., but it is definitely a good start point.

Good luck!
