Assume you've been recruited to create an application that aids in the batch processing of database operations. You must design a graphical user interface (GUI) application that allows you to add different jobs defined in the form of SQL procedures or functions and execute them in sequence. This task scheduling allows for the addition and execution of dependent tasks, parent tasks must be completed before child tasks. While developing this a workflow or task scheduling application, you can build application taking account of particular scenario of your choice for example implementation of batch processing or job scheduling required for financial and invoice calculation for sample consumers. Application must allow users to create their own profile.

1. Application allow user to add tasks or jobs

2. Application should allow user to define control flow of the jobs or create pipeline of the jobs

3. Application should allow users to remove tasks

4. Application should allow uses to resume tasks at position after sudden failure

5. Parent tasks needed to be executed before executing child tasks.
