Creating Geodatabases using Arcpy or Model builder

Creating Geo-databases in Arc Map

What is a Geodatabase:

• A geodatabase is the common data storage and management framework for all the ArcGIS Products. It combines Geo (spatial data) with Database (data repository) to create a central data repository for all the spatial data storage and management in your ArcGIS platform.
• It can be leveraged in desktop, server, or mobile environments and allows you to store GIS data in a central location for easy access and management.

The geodatabase offers you the ability to

• Store a rich collection of spatial data in a centralized location.
• Apply sophisticated rules and relationships to the data.
• Define advanced geospatial relational models (e.g., topologies, networks).
• Maintain integrity of spatial data with a consistent, accurate database.
• Work within a multiuser access and editing environment.
• Integrate spatial data with other IT databases.
• Easily scale your storage solution.
• Support custom features and behavior.
• Leverage your spatial data to its full potential.

Arc-map geodatabase can be created using various way:

1. Manually creating through Arc-Catalog
2. Using the Model workflow to create it Programmatic-ally
3. Using the Python integrated to Create Geodatabase Programmatic

1. Model for Creating Feature Class

Model to create Geodatabase in ArcGIS

Set the workspace and OutputFC as the Model parameter

AddField will add a column to the newly created Feature class and can be populated with the user defined values

The Search, Insert or Update cursor can be used to manipulate the values present in the new Feature class

For achieving the above functionality it is advised to write a python code using the arcpy library.
