Answer to Question 1

An entity class is the collection of all entities of a given type. The entity class is described by the structure of the entities in that class. An entity instance is a representation of a particular entity within the entity class. The entity instance is described by the values of the attributes of the entity. An entity class, then, is a collection containing many entity instances.

Answer to Question 2

Microsoft Access 2013 files can be secured using three methods: (1 ) by creating trusted locations for file storage, (2 ) by password encryption and decryption of database files, and (3 ) by deploying databases packaged with a digital signature. Additionally, Microsoft Access 2013 can compile VBA code used with an Access 2013 database file. Finally Microsoft Access 2013 can still use user-level security for older .mdb database files (but not for Access 2013 .accdb files).
