Linking Tables in ArcGIS 10.3: A Guide to Effective Data Management

Introduction:

When working with data in ArcGIS 10.3, you may find that you need information from multiple sources or tables. In this article, we will explore how linking tables together can help you manage your data more effectively and prevent duplicating information.

The Benefits of Linking Tables:

Linking tables allows you to combine data from different sources into a single database. This approach prevents duplicating information, as each piece of data is stored only once in one table. Most database design guidelines recommend organizing your database into multiple tables, each focused on a specific topic, rather than having a large table containing all necessary fields.

Using Joins, Relates, and Relationship Classes:

ArcGIS 10.3 provides various tools to link tables together. You can use joins, relates, and relationship classes to establish relationships between tables. Joins allow you to combine data from two or more tables based on common attributes. Relates enable you to specify the type of join used to link tables. Relationship classes define the rules for linking tables, ensuring that data is consistent and accurate.

Documentation and Tool Reference Pages:

The ArcGIS 10.3 help system provides extensive documentation for each tool, including the tool reference page. The tool reference page contains a summary of the tool's purpose, usage notes, and syntax information. Browsing through the documentation can be an effective way to learn about tools and their uses.

Common GIS Tools and Their Uses:

ArcGIS 10.3 includes hundreds of geoprocessing tools that can help you solve real-world problems. The best way to learn about these tools is by browsing through the documentation or exploring the Geoprocessing book in the help system. You can also start with an introduction to commonly used GIS tools.

Linking tables in ArcGIS 10.3 is a powerful tool for managing data effectively and preventing duplicating information. By understanding how to use joins, relates, and relationship classes, you can establish relationships between tables and combine data from different sources. Remember to consult the documentation and tool reference pages to learn more about each tool and its uses. With ArcGIS 10.3, you have access to a comprehensive set of geoprocessing tools that can help you solve real-world problems.
