Feature dataset: This is a collection of feature classes stored together in a geodatabase<br />

that share the same spatial reference; that is, they share a coordinate system, and their<br />

features fall within a common geographic area. Feature classes with different geometry<br />

types (points, lines, and polygons) may be stored together in a single feature dataset.<br />

Feature datasets are required for the use of geodatabase topologies and geometric<br />

networks.<br />

Fields: These are the columns in a database table and are used to store values associated<br />

with records. These must have unique names that do not contain special characters with<br />

the exception of an underscore (_). Fields must also be assigned a data type that<br />

determines what type of information can be stored within the field. Common field types<br />

include Text, Date, Long Integer, Short Integer, Float, and Double.<br />

Geodatabase: This is the native data format for <strong>ArcGIS</strong>. There are three basic types:<br />

personal, file, and SDE. SDE Geodatabases come in three types personal, workgroup and<br />

enterprise. Workgroup and enterprise geodatabases require <strong>ArcGIS</strong> for Server.<br />

Geodatabases store various types of geographic datasets including feature classes, tables,<br />

raster datasets, network datasets, topologies, address locators, custom toolboxes, and many<br />

others.<br />

Geoprocessing: This means the manipulation of data within <strong>ArcGIS</strong>. Usually, it is<br />

associated with the use of geoprocessing tools. The process of converting, managing, and<br />

analyzing data is considered as geoprocessing.<br />

Geoprocessing tools: These are tools that allow users to manipulate data within the<br />

<strong>ArcGIS</strong> Platform. Tool availability is determined by licensing levels and available<br />

extensions. They can be accessed in many different ways, including toolboxes, Python,<br />

ModelBuilder, and custom applications.<br />

Geocoding: This is the act of turning an address into a point location. It requires the<br />

following three components: address or list of addresses, reference data (GIS data with<br />

address information), and a locator, which translates between the other two components.<br />

Integer: This is a whole number; that is, it has no fractions or decimal values.<br />

Join: This is one of the two ways to link two tables together in ArcMap or <strong>ArcGIS</strong> <strong>Pro</strong>.<br />

This requires a cardinality of one to one or many to one. It creates a virtual link between<br />

the two tables so that within your map document or <strong>ArcGIS</strong> <strong>Pro</strong> project, the two tables<br />

appear as one. You may then use the data from both tables to query, label, and symbolize<br />

features.<br />

Labels: Labeling is an easy way to add descriptive text to features on your map. Labels<br />

are dynamically placed, and label text strings are based on feature attributes. You can turn<br />

labels on or off as a group. They can also be locked, so their locations stay fixed as you<br />

zoom or pan on your map.<br />

Layer: This is any spatial or tabular data displayed or accessed within a map or scene. It is<br />

located in the Contents pane in <strong>ArcGIS</strong> <strong>Pro</strong> or the Table of Contents in ArcMap. Layers<br />

have properties, including Name, Symbology, Label Settings, Display settings, and
