are you familiar with database? there are operators such as select, delete, insert and join. I am asking you to do the hash join algorithm "you can find it in the slides" it is about showing a simulation of how the hash join algorithm work, the user insert the hash function and memory size as in the examples and shows the 2 relations with partitions and buffers as in slide 31 to 37. in the attachment you will find the hole chapter. I want it in 12/5/2012. I prefer Java and I want it to work on eclipse.
