This project implements the multidimensional databases operators for Rakesh Agrawal's paper. Rakesh Agrawal, Ashish Gupta, and Sunita Sarawagi. 1997. Modeling Multidimensional Databases.

Plan to support operators:

• Pull
• Push
• Distory dimension
• Restriction
• Join
• Associate
• Merge

Usage:

Before start

1. Edit config.json to connect to MySql backend
2. Start cube.py in interactive mode

Example

Date	Supplier	Product	Sales
Jan 1	S1	p1	5
Sept 1	S2	P2	9

Import a cube from backend

c1 = Cube(t1)

save to backend

c1.save(t1)

Visualize a cube

c1.visualize()

Use operators

c = c1.push("product") #push "product" dimension into elements

c = c1.join(c2,[f1...k, f'1...k], [f_elem], [dimensions...])
