Overview of the Current Status of NoSQL Database

Nowadays with the accelerated development of the Internet and Cloud computing, the fast growth of technology generates a massive amount of data. Businesses and people generate these data by using web apps, social media, and new technologies. These data, in general, could be structured, semi-structured or unstructured. Because of the different types of data and the big data that is generated, there is a need for a database to be able to store and process these data effectively to enhance the performance when reading and writing. So, there is a need for a new design for the database, and it is not suitable for storing, analyzing and performing data in a relational database for big data. In addition to that, many new challenges faced the traditional relational database; especially in the applications that required large scale and high concurrency such as search engines. In response to that, NoSQL has developed to solve these types of problem. NoSQL database has many advantages that make it gain significant popularity over the last few years and used widely. It read and write the data quickly, expands easily, low cost and many other features. In this paper, we overview the NoSQL database and its characteristics in the field of the Internet of Things (IoT). We also provide two representative use cases of using the NoSQL database in current technologies.
