query and update the text database for a library , JAVA Programming

Assignment Help:
Implement a program to query and update the text database for a library using a client/server model allowing multiple clients safe access to the database, and using a producer-consumer model to control the inventory of each item.
The project will be graded according the criteria for the final project - see below.
Elaboration:
1. Multiple instances of a client class should be supported.
2. Use threads and locks to provide safe access to the database.
3. Add a field to each record in the dok kooatabase representing the maximum number of that book the library will hold. This number should be given a default value if the field is not present in the text file.
4. Functions should include:
o Returning a book to the library, blocking if the maximum number of that book is reached until a book is borrowed.
o Borrowing a book, blocking if the desired book is not in the library until a book is returned.
o Allow a client to cancel a request that has been blocked.
Deliverables
1. Java source code files
2. any configuration files used
3. a well-written Word document describing:
a. your overall design, including a UML class diagram showing the type of the class relationships
