Everything you need to know about service integration development, even for non-experts.

Description
Book Introduction
Behind every service you use every day, there is an invisible technology of 'connection' hidden.
Check in real time where your food is on the way from a delivery app, log in with Kakao with a single touch, and receive a text message from your credit card company the moment you press the payment button on a shopping mall—all these magical experiences.
How is this possible?
"Everything About Service Integration Development, Understandable Even for Non-Majors" is the most user-friendly guide that delves into the technology of "connection," that is, everything about service integration.
This book won't lead you into the world of coding.
Instead, it presents the perspective of an architect who designs the 'skeleton' of a service.
Journey with this book:
Part 1, 2 [Finding the Source of Data]: We'll open the door to the "database," the storehouse of all information. We'll learn the principles of massive data migration operations, using SQL to extract data (SELECT) and transfer data from other warehouses (ETL).
Part 3 [Standard Diplomacy in the Web World]: Exploring the world of 'APIs', the official way for services around the world to communicate.
You'll clearly understand the difference between a REST API like a vending machine, a GraphQL personal shopping assistant, and a webhook like a magazine subscription.
Part 4 [The Secret of High-Performance Real-Time Communication]: A look into the secret weapons of services that don't tolerate even 0.1 second of delay.
We explore the principles of gRPC, which enables ultra-fast communication between internal systems, WebSocket, which enables real-time chat, and message queues, which survive even under high traffic.
Part 5 [Practical! Designing Your Own System]: By combining all the skills you've learned so far, you'll perfect your problem-solving skills through a practical case study where you'll design a "data analysis platform" and a "real-time order notification system."
This book is a must-read for:
Prospective Planner/PM: Someone who wants to translate ideas into technical specifications that developers can understand.
IT Sales/Marketing Representative: Someone who wants to logically and confidently explain the technical value of our solutions to customers.
Anyone who collaborates with developers: Anyone who wants to stop dreading meeting times and drive projects to success through productive communication.
Anyone who wants to stay abreast of IT trends: anyone who wants to understand the inner workings of the technologies that power the world and improve their digital literacy.
Through familiar metaphors and concrete scenarios like "restaurants," "vending machines," and "delivery systems," this book will naturally integrate complex technical concepts into your intuition.
Don't hesitate in front of technological barriers anymore.
Understand the principles of 'connection' and become a true expert who connects business and technology.
