It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and stored sets. Redis is written in c language. And these Redis concepts needs to create the performance oriented system and deployed a highly salable. The goal of this is to give a basic understanding of what exactly Redis does and how it differs from other database,both relational and NoSQL. And equip the user with the knowledge and need to able to start using Redis with a real application. But has to be feel comfortable enough with Redis, and explain how Redis work to decide if Redis would be a good choice for a data store for the application. If the client comes from a relational database background, the user probably find Redis to be very different from any database. Even if the client uses some NoSQL databases like Ravendb or Mongodb and probably still finds Redis to be quite unique and it is critical to understand what exactly how this Redis operations are performed and properly set the expectation moving forward. Redis is an open source database. Redis is bit different than jut a dictionary or a map, because even through it uses keys and values, the values are actually structured data types, like lists, sets and hashes.
