Help -- you are assigned to implement a minimal relational model emulator using Java programming language that can provide basic relational model and algebra functionalities in-memory. This means that your emulator will perform the operations in the run time and do not have to actually store the data . A successfully implemented emulator will be able to create relational model elements such as relations, tuples, and attributes, check the validity/constraints of the relation descriptions and relation instances, enforce those constraints, enable data modification and certain retrieval operations outlined below. You will use Relation implementation ( Relation.java, Tuple.java, Attribute.java along with Driver.java) and You are expected to use standard Java libraries and not utilize additional libraries that implement data frames or SQL connectors/emulators. The purpose of this project is to gain understanding on how the relational model features can be implemented; it is not utilizing third party libraries in Java.
