What is a .DDL file?
A .DDL file is a type of database file. It is made using a special language called Data Definition Language, or DDL for short. This language is used to describe how a database should be structured. Think of it as a blueprint for setting up the rooms (tables) in a database house. The file is usually just plain text, which means it's easy to read and write. Inside a .DDL file, you'll find commands like CREATE, which is used to make a new table; USE, to select which database to work with; ALTER, to change an existing table; and DROP, to delete a table. These commands help in organizing and managing the data sources that data-driven applications need to function.
You can open .DDL files with several programs. Two specific ones are JetBrains IntelliJ IDEA and EclipseLink, which are tools used by programmers, especially those working with Java. However, because .DDL files are in plain text, you can also use any text editor to open them. This means programs like Notepad on Windows, TextEdit on Mac, or any other basic text editing software can work with .DDL files.
It's important to know that DDL is part of a larger language called SQL, or Structured Query Language. SQL is the standard language for dealing with databases, and DDL focuses specifically on the structure or schema of the database, rather than adding, changing, or looking at the data itself.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
