Spring Boot Redis CRUD Example java Redis Spring Boot by devs5003 - June 26, 2023November 15, 20256 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'. 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
Spring Boot MongoDB Java Tutorial With Examples Spring Boot java MongoDB Spring by devs5003 - June 10, 2023April 9, 20264 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

How to implement Security in Spring Boot Project? Spring Boot java Spring Spring Boot 3 by devs5003 - February 19, 2023April 7, 20265 Now a days, almost every client demands for implementation of powerful security feature in real time application. Demand of security feature is very valid to maintain confidentiality, integrity and availability. There are many types of security in the real world, but we as a developer will focus on the Application/Software Security. Furthermore, in Application Security, our job is to ensure basically two things. First, only valid user can access the application. Second, If the user is valid, he/she can access only permitted data/information in that application. I consider, there is nothing to explain more about them as you must already be aware of these two terminologies i.e. Authentication & Authorization.
