ABSTRACT

4 | P a g e

ONLINE JUDGE DATABASE IS A UNIQUE DATABASE SYSTEM THAT HELPS

INSTRUCTORS TO VIEW HOW MANY PROBLEMS SOLVED AND TOUCHED BY CONTESTENTS.

IT IS THE BEST WAY THAT ENHANCE OUR KNOWLEDGE ABOUT PROGRAMMING.

IT IS THE ONLY WAY TO ARRANGE AN INTERNATIONAL PROGRAMMING CONTEST.

PREVIOUS SYSTEM

5 | P a g e

PREVIOUS SYSTEM REQUIRE HUMAN INTERFACR FOR JUDGEING THE

PROBLEMS. IT IS ALMOST IMPOSSIBLE TO CHECK MILLIONS OF PROBLEM BY HUMAN. BUT THIS ADVANCED DATABASE SYSTEM CHANGES EVERYTHING. IT CAN CHECK MILLIONS OF PROBLEMS WITHIN FEW MOMENTS.

IDENTIFICATION NEED

ONLINE JUDGE DATABASE SYSTEM IS USE TO STORE INFORMATION ABOUT

MILLIONS OF USER, PROBLEMS, PROBLEM SETTER, AND STATUS OF SUBMITTED PROBLEM AND MOST IMPORTANTLY ARRANGE PROGRAMMING CONTAST. THIS KIND OF DATABASE NOW MOSTLY NEEDED FOR MAKING OUR LIFE EASIER.

DEVELOPED SYSTEM

THIS DATABASE SYSTEM ARE ABLE TO KEEP ALL USERS, PROBLEMS, PROBLEM

SETTER, AND MOST IMPORTANTLY IT’S CONTAINS HUGE COMPILER WHICH CAN USED MULTIPLE PROGRAMMING LANGUAGE AND its TASKING CAPACITY 24×365.

PROBLEM ANALYSIS

PROBLEM STATEMENT:THE OBJECTIVE OF THIS PORJECT IS TO

REDESIGN AND DEVELOP ONLINE JUDGE MANAGEMENT

DATABASE SYSTEM.

TECHNOLOGIES:Oracle Database 11g Express Edition IS USED TO SUCESSFULLY DO THIS PROJECT.

2. Show the info of member and there problem number that they were failed to solved

= select m.M_ID, m.m_name, count(ms.p_id) from mamber m, my_submission ms where (m.m_id = ms.m_id) and (ms.status = 0) GROUP BY m.M_ID, m.m_name

3. Find info of problem which problem is solved and checked by at last 3 member

= select p.p_id, p.p_name from problem p, my_submission ms where (p.p_id = ms.p_id) and (ms.status = 1) group by p.p_id, p.p_name having count(ms.m_id) >=3

4. Find the problem setter and problem info which problem is not solved

= select p.p_id, p.p_name, ps.ps_id, ps.ps_name from problem p, problem_setter ps, my_submission ms where (p.p_id = ms.p_id) and (p.ps_id = ps.ps_id) and (ms.status = 0) group by p.p_id, p.p_name, ps.ps_id, ps.ps_name

5. Find the info of the problems and volume number which is solved by java or C#
