system contains the following functionalities: 1. Data Definition part: a. define new tables: table name and attribute names b. for each defined table ask users to input possible FDs: trivial FDs should be weeded out, all FDs should be rewritten in non-trivial ones, and weak FDs should be ignored c. ask users to define keys for each table, if the user-defined keys disagree the keys reached by its FDs, deny them 2. Data Manipulation part: a. users can input new tuples to all tables, your system should deny those that violate FDs b. users can delete a tuple based on key value c. users can perform actions below for one table: i) find attribute(s) for tuples which satisfy conditions for some attributes ii) group tuples based on one chosen attribute d. users can choose to perform the following operators for two tables: cross join, natural join, union, intersection, difference e. users can delete a table To reduce the complexity of your program, the following constraints are in effect: 1. _at most_ five attributes for a table. 2. _at most_ five FDs for each table. 2. single character (upper case) attribute names. 3. the type for ALL attributes is integer.
