LARC tables are composed of LARC data elements. Each table entry provides: physical table name, logical table name, data set locations, and a table description. LARC diagrams show the logical relationships between LARC tables: a logical link between two tables indicates a direct data relationship between them, and physically, any two tables sharing a common element can be joined via a connecting line.
