Abstract
• As data volumes increase, and organizations are faced with data integration challenges associated with mergers and acquisitions, master data management, business intelligence, and/or data governance initiatives, the need to create consistent, reusable standards is more critical than ever before. Standards help increase efficiency and quality by promoting reuse across the organization.

Why use Enterprise Standards?
• Business decisions are based on data – bad data or design results in bad business decisions
• Benefits of using data standards:– Increased Efficiency
– Increased Data Quality
– Promotes Reuse and Communication across the organization.

Using Naming Standards
• What is a Naming Standard?
– A glossary of words and abbreviations that can be used in model object names
• Why use the Naming Standards Editor?
– Develop model naming standards
– Check model names for accuracy
– Name model objects in models derived from other models
– Reuse of standards across the enterprise

Using Domains
• What is a Domain?
– A set of values and rules assigned to a data element
• Example: Data types, Validation rules
– Used to quickly assign properties to columns
• Why use Domains?
– Speeds Design process
– Easy to maintain
– Use across entire model
PAGE 9
Using User Defined Properties (UDPs)
• What is a UDP ?
– Provides the ability to define custom model object properties
• Why use UDPs?
– Further documentation of model objects
– Clarification for users or viewers of models
– Standardize usage across models
• Examples of Common UDPs
– Data Stewards, Status, Document attachments, etc.

Using Datatype Standards
• What is a Datatype Standards file?
– Includes user-defined datatypes and mapping information that is needed to convert logical & physical datatypes.
• Why use a Datatype Standards file?
– Converting models from Logical to Physical
– Converting models from one Physical DBMS to another
– Deriving multiple models from one source
– Introducing new data types
PAGE 11
Using Model Templates with Standards
• What is a Model Template?
– A starting point for new models containing reusable objects such as:
• Domains
• Naming standards
• Formatting options
• Etc.
• Why use a Model Template?
– Provides Standardization and Reuse
– Speeds up development/altering of models/databases

Sharing Standards Using CA ERwin Model Manager
• What is CA ERwin Model Manager?
– Central location for storing standards, such as:
• Naming Standards
• Datatype Standards
• Model Templates
– Collaboration for use, reuse, and audit
• Why use CA ERwin Model Manager?
– Reuse of core data assets
– Efficiencies for team collaboration
– Access to other models for sharing objects via Complete Compare

Reporting to Stakeholders
• Sharing information in customizable formats
• CA ERwin Data Modeler provides multiple reporting options – HTML
– Text
– RTF
– Crystal Reports
– OBDC queries
• In addition, these reports may be filtered by Subject Areas or Stored Displays
