Geodatabase design steps…part 2

Step 6. Establish the integrity guidelines, geographical linkages, and spatial behavior for your datasets.

For features, you may use topologies, address locators, networks, terrains, and other things like them to add spatial behavior and capabilities as well as characterize the spatial links that your linked features have by themselves. Use topologies, for instance, to enforce integrity constraints and describe the spatial interactions of shared geometry. Geocoding can be supported by address locators.

Utilize networks for pathfinding and tracing. You can choose whether a raster dataset or raster catalog is required for rasters.

Step 7. suggest a geodatabase layout.

Decide the geodatabase components you wish to use for each data theme in your design. Look at current designs for successful concepts and strategies. Take inspiration from the ArcGIS data models’ patterns and best practices.

Step 8. Map display settings and design editing processes.

Establish the editing processes and integrity standards (for example, all streets are split where they intersect other streets, and street segments connect at endpoints).

Create editing processes that assist you in maintaining the data’s integrity. Define the display settings for 3D views and maps. For each map scale, determine the map display characteristics. Map layers will be defined using these.

Step 9. Establish who will be responsible for creating and maintaining each data layer.

Decide who will be responsible for maintaining your organization’s data or if other organizations will be tasked with this task.

It’s critical to comprehend their functions. To import and export data among diverse partner companies, you must plan how data conversion and transformation will be used.

step 10. Create a functional prototype. Examine and improve your design

A prototype should be tested. Make a file, personal, or business geodatabase sample copy of your suggested design. To evaluate the design’s usefulness, create maps, launch important programs, and carry out editing tasks.

Refine and improve your design in light of the outcomes of your prototype testing. Once you have a workable schema, load a bigger collection of data to test production, performance, scalability, and data management operations (for example, by loading it into an enterprise geodatabase). This is a crucial action. Before you start adding data to your geodatabase, decide on your design.

Step 11. Record the design of your geodatabase.

Your database design and choices may be explained using a variety of techniques. Use illustrations, model map layers, schema diagrams, easy reporting, and metadata records. Some people like using UML in their job. UML, though, is insufficient on its own.

The spatial attributes and choices that must be made cannot all be represented by UML. Additionally, UML does not explain important GIS design ideas like network connection, topological rules, and thematic organization. No spatial understanding of your design is provided by UML.

Many customers use Visio to build a visual representation of their geodatabase schema, similar to the ones shared with ArcGIS data models. You may use a tool from Esri to use Visio to record these kind of visuals for your data model components.
