Assuming previously defined Attribute, compiled in a vector known as 'vec' and with subsequent numbers added

To create a table:

	engine.createTable("table1", vec);


This creates a Relation object with the appropriate Attribute objects. It displays nothing.

To display the table:

	engine.showTables(engine.getTableFromName("table1"));


This results in such output:

	Display of relation--------------------------------
	Relation name: table1

	Attribute name: name
	Elements: Fry      Bender      Leela      Zoidberg
	Attribute name: age
	Elements: 22      5      22      50      


With table3 having an equal domain to table1, this:

	cout << engine.unionComp(engine.getTableFromName("table1"), engine.getTableFromName("table3"));


This will display:

	1


To project a table's column:
	
	engine.project((engine.getTableFromName("table1")), "name");


This will display:

	-----------Initiated Query Projection---------
	Column Title: name
	Fry
	Bender
	Leela
	Zoidberg


With an arbitrary vector of strings as cmds (until we are able to parse effectively):

	engine.saveToFile(cmds);


This will result in a db file with the contents:

	CREATE TABLE animals (name VARCHAR(20), kind VARCHAR(8), years INTEGER) PRIMARY KEY (name, kind);
	
SHOW animals;



//insert

//delete

//select

//product
