This scenario outlines the process of forward engineering using IBM Infosphere Data Architect to transform a logical data model into a physical data model and generate a DDL (Data Definition Language) script for database creation. Here's a summary of the steps involved:
1. Launch IBM Infosphere Data Architect and create a new "Data Design Project."
2. Import a logical data model from a source such as CA Erwin Data Modeler into the project.
3. Provide necessary details and configure the import settings.
4. Once imported, inspect the logical data model, which includes entities and their attributes.
5. Optionally, create diagrams to visualize the data model.
6. Modify the logical data model as needed, adding new entities or relationships.
7. Transform the logical data model into a physical data model tailored for a specific database management system (DBMS) like MySQL.
8. Specify the destination folder, filename, and compatibility settings for the physical model.
9. Review and adjust transformation options if necessary before proceeding.
10. After transformation, inspect the generated physical data model, which includes tables, columns, and relationships.
11. Generate a DDL script for creating the database schema, specifying the output file name and location.
12. Optionally, review and run the DDL script on the MySQL database server.
13. Establish a connection to the MySQL database server if not already done.
14. Run the generated SQL script to create the database schema, which includes tables and their structures.
Throughout the process, attention to detail and careful consideration of the database design and transformation settings are crucial. Additionally, collaboration with database administrators (DBAs) is recommended to review and validate the generated DDL script before executing it on the MySQL database server.
