Creating a Java application using a Red Black Tree to implement a database management system would involve the following steps:

1. Develop an appropriate data structure for the Red Black Tree. This can be done by defining the fields of the node, including any specific data type information for each field.

2. Then, create an appropriate function for inserting elements into the tree. This function should make sure to insert the element at the correct spot, while maintaining the Red Black Trees invariants.

3. Create the functions for updating, deleting and searching data from the Red Black Tree. These functions should be able to handle changes to the data structure made during insertion and deletion.

4. After implementing the Red Black Tree, write the code for the database management system (DBMS). This code should: a. Allow the user to input employee details, such as name, contact details and job title,employee_id, gender, employee name, age, employee address, employee designation, and salary b. Implement the logic for integrity checks while entering employee data. c. Store the employee details in the Red Black Tree. d. Allow the user to search the tree using different search criteria and retrieve details quickly. e. Allow the user to update and delete existing entries.

5. Lastly, create the user interface for the program. This will enable the user to interact with the DBMS.
