Introduction to Programming

By: Nick Samoylov

Overview of this book

Have you ever thought about making your computer do what you want it to do? Do you want to learn to program, but just don't know where to start? Instead of guiding you in the right direction, have other learning resources got you confused with over-explanations? Don't worry. Look no further. Introduction to Programming is here to help. Written by an industry expert who understands the challenges faced by those from a non-programming background, this book takes a gentle, hand-holding approach to introducing you to the world of programming. Beginning with an introduction to what programming is, you'll go on to learn about languages, their syntax, and development environments. With plenty of examples for you to code alongside reading, the book's practical approach will help you to grasp everything it has to offer. More importantly, you'll understand several aspects of application development. As a result, you'll have your very own application running by the end of the book. To help you comprehensively understand Java programming, there are exercises at the end of each chapter to keep things interesting and encourage you to add your own personal touch to the code and, ultimately, your application.

In order for a deployable unit of code to be qualified as a microservice, it has to possess the following characteristics:

  • The size of the source code of one microservice should be smaller than the size of a traditional application. Another size criteria is that one programmer's team should be able to write and support several of them.
  • It has to be deployed independently. Naturally, one microservice typically cooperates and expects cooperation from other systems, but that should not prevent our ability to deploy it.
  • If a microservice uses a database to store data, it has to have its own schema, or a set of tables. This statement is still under debate, especially in cases when several services modify the same data set or interdependent datasets. If the same team owns all of the related services, it is easier to accomplish. Otherwise, there are several possible...
