  • 3. Agenda
    To understand what Data Modeling is.
    To understand why a company needs to Data Model.

    What’s in R7.3?
  • 4. 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
    A DATABASE MODEL is a graphical representation of a database which is depicted by using an Entity Relationship Diagram (ERD)
    Data Model (ERD)
  • 5. SQL vs. Model
    product_id INTEGER NOT NULL,
    product_name VARCHAR(50) NULL,
    product_price NUMBER NULL);
    ADD ( PRIMARY KEY (product_id) ) ;
    department_id INTEGER NOT NULL,
    department_name VARCHAR(50) NULL);
    ADD ( PRIMARY KEY (department_id) ) ;
    department_id INTEGER NOT NULL,
    employee_fname VARCHAR(50) NULL,
    employee_lname VARCHAR(50) NULL,
    employee_ssn CHAR(9) NULL);

  • 40. CA ERwin® Modeling Questions?
  • 41. 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
  • 42. 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.
  • 43. 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
