If you are new to geodatabases or want to learn more, the following topics provide a conceptual overview to get you started.
An overview of the geodatabase
The topics in this section of the help describe the fundamental contents for every geodatabase: tables, features, and rasters. Start with the topic named Table basics and read all the following topics in this help section.
The architecture of the geodatabase
The architecture of a geodatabase explains the geodatabase storage model and how it leverages relational database technology. This information is not required to use the geodatabase. It provides good background information for the geodatabase and how you can leverage it in your daily use.
Designing a geodatabase
This is a practical overview on design and a simple procedure you can follow to help you build your geodatabase.
Creating a geodatabase
How you create a geodatabase varies by the type of geodatabase you want to use.
Feature class design
This feature class design topic helps to explain why you would extend a feature class with additional capabilities (such as a topology, network, or terrain) and points you to more information on implementation.
Adding datasets and other geodatabase elements
To begin populating your geodatabase with data, see An overview of adding datasets to the geodatabase.
For information on updating the data in your geodatabase, see the topics in the Editing section.
Managing distributed data
When you work with multiuser geodatabases and want to distribute copies of your geodatabase across (and even outside) your organization, you can use replication.
Configuring and maintaining geodatabases are covered in the Administering geodatabases topics.
Using SQL with geodatabases
These topics cover using SQL clients to access data in enterprise geodatabases. This section also covers using SQL to access the ST_Geometry type in Oracle, PostgreSQL, and SQLite.
