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

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
