In this chapter, you learned about the different data types, and options to store and work with data that are used frequently nowadays. It is important that you understand the different aims of the different data stores, as all of them have their advantages and disadvantages. It is highly recommended that you get familiar with these data stores and start working with them. Keep in mind that we only scratched the surface of each data type, and that the complexity of your solutions and the resulting code will quickly increase. In addition, there are some specific data types that we completely missed, such as NoSQL and graphs. As we advance through the book, we will continue to work with many of the data types mentioned in this chapter to increase the reader's knowledge.
