Spring Boot Redis CRUD Example
As a Java developer, if we talk about data layer, we can’t develop an insightful application without the use of CRUD Operations. We might have developed CRUD operations multiple times using a relational database such as My SQL, SQL Server, Oracle etc. However, this time we are going to use a NoSQL Database which is different than a relational database. Here, we will use the Redis database to implement CRUD operations using Spring Boot. Hence, our article for the discussion is 'Spring Boot Redis CRUD Example'.

Spring Boot MongoDB Tutorial
As a Java developer, we can't develop an insightful application without the use of a database software. Traditionally, we use a relational database to work with an application. Of course, A relational database is a structured database and contains multiple tables to maintain meaningful relations between them. Additionally, it uses SQL like queries to operate with data stored in the tables. In contrast, suppose we have to work with a large amount of unstructured data which is not beneficial to store in the form of tables, keeping other factors in mind as well, then how will we store our data? The simple answer is 'we should use MongoDB' in that case. Further, you might even have some other questions in your
