The concept of this paper helps resolve an ER schema into an appropriate relational Data Description Language (herein standard SQL statements) while considering all the inherent complexity of such a schema. The algorithm resolves all the relationships between the concerned entities (even weak ones), their associated keys - primary and foreign, attributes - simple, composite and multivalued and relationships types from binary to n-ary. The algorithm (as implemented in ANSI C) is smart enough to consider the case of cascading weak entities
