How are all of these tables related?: Relational database map -: RDB_MAP.SAS

This simple, yet highly useful SAS(R) program generates a "relational map" of permanent SAS datasets or SAS/ACCESS(R) views within a common libname reference. Basically, RDB MAP.SAS produces a tabular or matrix report showing the common variables shared by all the datasets or views in the libname. The column headings of the report are the SAS dataset or view names and the row headings are all the SAS variable names. An 'X' (or your favorite alpha-numeric character or word) is printed under the dataset or view the variable is found. One can then easily see which tables share a common variable. RDB_MAP.SAS utilizes the SASHELP.VCOLUMN dataset, a PROC SORT, a PROC TRANSPOSE, and a simple PROC PRINT. This is a fast and easy way to display all relationships between multiple tables of information.
