Who is responsible for maintenance?
There are several possible configurations!
Database Design and Infrastructure
Preparation: Understand the current workflow– Take an inventory of documents– Make diagrams : Entity-Relationship & Network
Critique – Ways to improve efficiency– Communication
Decisions– Make a plan and designate a coordinator– Set Goals and a Timeline
Implementation– Contingency Plan– Training
Aftermath– Analysis– Maps
Maintenance Tips
Use the Geodatabase Model– Central Storage– Feature Datasets
Reduce the number of GIS layers “actively” maintained – relationships, domains, and subtypes
Integrate the Tax/CAMA systems with the GIS Utilize the customization abilities in ArcGIS to create
routines or tools that minimize steps– Model Builder
Spatial Relational Database Management Systems
RDBMS Types of data
– Numeric– Text– Yes/no– Date
Very Powerful– The “glue” of the GIS Precinct

Geodatabase Rules
Domains: acceptable values – Range– Coded Values
Subtypes: classification of features within feature class
Relationship Classes: defines a set of valid associations between two feature classes or tables
Domains
Created in Geodatabase or through ArcToolbox
Add the Coded value or Range of values
Associate Domain to a feature class

Subtypes
One Feature Class– Subtype associated to FC field
Working with subsets– substitutions
Default subtype Annotation Tools in Arc
Relationship Classes
Tag Data Model
Coincident Geographic Features– The solution is Multiple Feature Tagging
