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)

SQL vs. Model product_id INTEGER NOT NULL, product_name VARCHAR(50) NULL, product_price NUMBER NULL);

ALTER TABLE PRODUCT ADD ( PRIMARY KEY (product_id) ) ;

CREATE TABLE DEPARTMENT ( department_id INTEGER NOT NULL, department_name VARCHAR(50) NULL);

ALTER TABLE DEPARTMENT ADD ( PRIMARY KEY (department_id) ) ;

CREATE TABLE EMPLOYEE (employee_id INTEGER NOT NULL, department_id INTEGER NOT NULL, employee_fname VARCHAR(50) NULL, employee_lname VARCHAR(50) NULL, employee_ssn CHAR(9) NULL);ALTER TABLE EMPLOYEE ADD ( PRIMARY KEY (employee_id) ) ;

CREATE TABLE CUSTOMER ( customer_id INTEGER NOT NULL, customer_name VARCHAR(50) NULL, customer_address VARCHAR(150) NULL, customer_city VARCHAR(50) NULL, customer_state CHAR(2) NULL, customer_zip CHAR(9) NULL);

ALTER TABLE CUSTOMER ADD ( PRIMARY KEY (customer_id) ) ;

CREATE TABLE ZORDER ( zorder_id INTEGER NOT NULL, employee_id INTEGER NOT NULL, customer_id INTEGER NOT NULL, zorder_date DATE NULL);

ALTER TABLE ZORDER ADD ( PRIMARY KEY (zorder_id) ) ;

Why Do You Need a Data Model?> With a single graphical model, you can manage

multiple databases on diverse platforms.

Why Do You Need a Data Model?

> Would you navigate a strange city without a map?

> Maybe…you could always read the road signs

Why Do You Need a Data Model?> But what if you were traveling in several foreign cities,

and couldn’t possibly learn every language for your trip?

I think we need more explanation here--people seemed confused by this on the Beta call. Maybe mention that there is no database needed--it's the ability to query models in ERwin itself?

CA ERwin® Modeling Questions?

38April 8, 2023


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.

40April 8, 2023


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
