True or False: Logical database design is the process of modifying the physical database design to improve performance. The two major logical database design techniques are conversion of E-R diagrams to relational tables and data normalization. Multivalued attributes are not permitted in unnormalized data. A many-to-many binary relationship in an E-R diagram requires the creation of a total of three tables in a relational database. A one-to-one unary relationship in an E-R diagram requires the creation of a total of...
