We
offers a series of training courses in ESRI GIS
software. Whether you are new to GIS or have been
using the technology for years, these courses are
a fast and cost-effective way of becoming a successful
ESRI software user.
Overview
A
well-planned and efficient design
is critical to the success of
a geodatabase implementation.
This course explains the steps
involved in the geodatabase
design process, from preliminary
planning to schema creation.
You learn how to take advantage
of existing ArcGIS data models
and become familiar with data
modeling techniques. A review
of basic geodatabase concepts
is included.
Topics
Covered
Introduction
to the geodatabase: Background
information on geodatabase
capabilities and advantages;
Storage options; Geodatabase
elements; Behavior in the
geodatabase.
Overview
of geodatabase design: What
to expect at each phase; Overview
of Inception phase; Overview
of Elaboration phase; Overview
of Construction phase; Overview
of Transition phase.
Building
the conceptual model: Identifying
concepts from the Inception
phase; Diagramming the conceptual
model; Recognizing crucial
data layers, attributes, and
their associations.
Layers
and attributes in the logical
data model: Mapping thematic
layers to elements of the
geodatabase; Defining properties
for each table; Choosing geometry
for feature classes; Designing
and diagramming attributes
and attribute properties;
Determining and diagramming
attribute domains; Grouping
features into feature datasets
or by subtype.
Relationships
in the logical data model:
Normalization; Implementing
associations; Relationship
classes; Modeling relationships;
Relationship properties and
cardinality; Attributed relationships;
Simple vs. composite relationships;
Messaging and relationships;
Relationships and subtypes;

ArcMap joins and relates vs.
relationship classes; Diagramming
relationships.
Geometric
networks and topology in the
logical data model: Introducing
geometric networks; Investigating
complex features and network
weights; Defining connectivity
rules; Diagramming geometric
network; Diagramming edge-to-junction
and edge-to-edge connectivity
rules; Topology in the geodatabase;
Examining topology rules;
Diagramming topology; Geodatabase
topology vs. map topology.
The
physical data model: Ways
to build geodatabase schema;
Building schema with CASE
tools; Building schema by
importing existing data; Creating
new geodatabase elements in
using ArcCatalog wizards;
Sharing and editing schema
with the Geodatabase Designer;
CASE tools vs. ArcCatalog.
From
design to geodatabase: Outline
construction and transition
phases; Determining data automation
method and considerations;
Data loading options; Testing
the geodatabase design in
a pilot study; Choosing a
pilot area; Documenting the
pilot project; Managing metadata;
Project tracking.
