This course will teach you how to seamlessly integrate Spring Data with various data sources, including relational and nonrelational databases, map-reduce frameworks, and cloud-based data services. 

You’ll start this course by exploring Spring Data JDBC and Spring Data JPA for efficient access to relational databases. Next, you’ll dive into NoSQL databases with Spring Data MongoDB and Spring Data Redis, venture into graph databases with Spring Data Neo4j, and explore the world of distributed databases with Spring Data for Apache Cassandra. Lastly, you’ll discover the power of Spring Data Elasticsearch. 

By the end of this course, you’ll emerge equipped with the knowledge and skills to leverage Spring Data effectively in diverse data-driven scenarios. You’ll be able to create applications seamlessly integrated with various data sources. This proficiency in Spring Data will enable you to design, build, and maintain applications that interact effortlessly with databases and data services.

Spring Data: Bridging Multiple Databases

Extend the existing library management system to include a fine calculation system on the book loans. We should be able to calculate the fine on the overdue book loans.

In this challenge, complete the following tasks:

1. Add the `Boolean` `available` property to the `Book` document class.

1. Add a method in the `BookRepository` repository to search the `Book` object with the matching `name` and `available` as either `Null` or `True`.

1. Create the `BookLoanEntry` class in the `com.smartdiscover.document` package to 
store the loan entry in MongoDB.

1. Add properties like `id`, `userFirstName`, `userLastName`, `loanDate`, `dueDate`, `returnDate`, and `status` to the `BookLoanEntry` POJO and add annotations to transform the POJO into a MongoDB document for managing the book loan.

1. Implement auditing metadata in the `BookLoanEntry` POJO to track the loan activity.

1. Create the `BookLoanEntryRepository` interface in the `com.smartdiscover.repository` package, which is a Mongo repository for the `BookLoanEntry` document.

1. Create the `FinePolicy` document class in the `com.smartdiscover.document` package with properties like `id`, `dailyFineRate`, `maxFineAmount`, and `active`. 

1. Create the `FinePolicyRepository` interface in the `com.smartdiscover.repository` package, which is a Mongo repository for the `FinePolicy` document.

1. Add the `findByActive` abstract method in the `FinePolicyRepository` to find an active policy.

1. Inject the `BookLoanRepository` and `FinePolicyRepository` repositories in the `SpringDataJpaApplication` and create methods like `loanBook`, `returnBook`, and `calculateFine` to perform the corresponding actions.

Challenge yourself to implement a fine calculation system using Spring Data MongoDB.
