Time is limited. That’s why it’s important to use it wisely. Programming is the art of finding solutions, and technology provides us with the tools to do so.
Today I want to introduce you to H2 Database, a system that will speed up your development process, by providing you an in-memory SQL database, easy to set set-up and ready to be used in your project.
Especially during the early stage of software development, this technology will help you set up a prototype, test different solutions, and deliver a clustered program that will greatly improve your efficiency.
