About Our SDDL Files


The files that are found in this data dictionary that map to the actual PMDB relations are called SDDL files. SDDL stands for Software Data Definition Language.

SDDL files are used by SPSS Software Developers to describe data. This data can map to the database and software applications and our SDDL compiler produces SQL, FORTRAN and C data structure definitions from the one source file!
