This article explains what a DDL file is and how to open or convert it on your computer.

A file with the DDL file extension is an SQL Data Definition Language file. These are plain text files that contain commands used to describe the structure of a database, such as its tables, records, columns, and other fields.

For example, given that certain syntax rules are followed, a DDL file can use the CREATE command to build domains, character sets, and tables. Other command examples include DROP, RENAME, and ALTER.

DDL files can be opened with EclipseLink or IntelliJ IDEA. Another method is to use an application that supports reading text files, such as the ones we hand-picked in this list of the best free text editors.
