What Is a DDL Script? How Do You Use It?
What is a DDL script and why is it so crucial for systems that use relational databases?
DDL scripts are widely used in creating, documenting, and migrating systems that use relational databases. They can be designed for simple tasks, such as migrating a database from one server to another, or for more complex tasks.
DDL scripts are read sequentially and are written in SQL with commands specific for defining data structures (CREATE, ALTER, and DROP).
A Complete Guide to Database Diagram Symbols
A complete guide to the symbols shown in entity-relationship diagrams (ERDs).
Although data modeling became a necessity around the 1970s, there was no standard way to model databases or business processes. Many solutions were proposed and discussed, but none were widely adopted.
Peter Chen is credited with creating the ER (entity-relationship) model, which introduced a way of mapping data model elements (which would become database elements) and their relationships. This model can serve as the diagram as well as the documentation for a database project.
