What is Database Modeling?
A MODEL is a graphical representation of a complex object, system or concept clarified through textual explanation
E.g. A blueprint
Database Data Model (ERD)
A DATABASE MODEL is a graphical representation of a database which is depicted by using an Entity Relationship Diagram (ERD)

What happens if we don’t Data Model?
> Database may be missing critical information
> Database development/maintenance time and cost are increased – over-budget!
> Poor database design – unstable system
> Missed project deadlines

CA ERwin® Modeling Questions?

Bottom Line….
> In today’s tough economy, IT resources are being asked to do more with less:
More databases to manage
More platforms to support
Fewer people to do the work.
> CA ERwin helps you face these challenges and look like a hero in their organization by:
Reducing the amount of time and money spent learning to code for every platform
Improving database performance through visual design
Increasing data quality through standardization and reuse
39April 8, 2023

Bottom Line…
> More Database Platforms to Support Most organizations have more than one database platform—it’s hard
to be an expert in all
The number of databases is growing, with more and more applications to support
CA ERwin can manage multiple databases from a single, graphical design.
> Fewer Staff and Resources Most organizations are cutting back on IT staff, making it difficult to
manage these growing databases.
Skill sets for individual databases are very specialized. It is unrealistic (and expensive) to have multiple experts for all platforms.
CA ERwin can replace the need to have experts in every platform—by managing multiple databases from a graphical model.

Bottom Line…
> Migrating Database Platforms
Many organizations are trying to consolidate databases into a single platform
CA ERwin can help in the migration process by translating the data structures from one platform to another.
> Integrating Data from Multiple Sources
Many organization are trying to integrate multiple systems – as a result of mergers and acquisitions, or for data warehousing,
CA ERwin helps create a single view of these data structures and creates standards
