Difference between how Oracle and SQLServer deal with indices1-Do some research and find out and explain the difference between how Oracle and SQLServer deal with indices; you have to go into more detail than what we have covered in class.

2-Do some research and find out and explain the difference between how Oracle and SQLServer deal with serializability.

3-Do some research and find out and explain the difference between how Oracle and SQLServer deal with 2 phase locking i.e. do they implement it, which variant etc.

4-: In the language of your choice write a program which will take as input a simple relational algebra statement (invloving only a selection and projection operation on a single table) and the table i.e. the relational instance. The output of your program should be the table that would have been output by the relational algebra statement. So what you have to do is to write a “compiler” type of program which will implement a relational algebra statement. Turn in a hard copy of the documented source code, and sample run (i.e. the relational algebra statment, the relational instance, the output table), and turn in the soft copy on blackboard.
