Welcome to Backend Development with Golang, Python, Flask, and MongoDB course. This is a comprehensive project based course where you will learn how to build two backend projects. The first one is inventory management system and the second is restaurant reservation system. This course is a perfect combination between backend development and database integration, making it an ideal opportunity to practice your programming skills while improving your technical knowledge in software development. In the introduction session, you will learn the basic fundamentals of backend development, such as getting to know CRUD operations, learn how to connect backend systems with databases, and also getting to know common issues in backend. Then, in the next section, we will install Golang and set up a MongoDB database, making sure your development environment is fully ready. Afterwards, we will start the first project. We are going to build an inventory management system using Golang. Firstly, we are going to create CRUD operations, enabling users to Add New Items, Update Items, and Delete Items. For each item, we will use a consistent data structure that includes name, SKU, quantity, price, supplier name, category, reorder Point, and lead time. Then, after that, we are also going to build an inventory dashboard where users can view all items, search and sort items by name, category and stock level. Additionally, the users will also be able to monitor the quantity of each item in real time and most importantly, the data will be updated whenever items are added, sold, or removed. Following that, we are going to create a low stock notification which will automatically alert users when the quantity of an item falls below its reorder point, helping to prevent stockouts. The inventory management system will also have reports and analytics tab, where users can view total items, low stock items, total inventory value, and visual charts representing stock level by category and average lead time by category. Meanwhile, in the second project, we are going to build a restaurant table reservation system using Python, Flask, and MongoDB. Firstly, we are going to create CRUD operations, the users will be able to add table reservation, update reservation, and cancel reservation, additionally, they can also select the date and time for their booking. Each reservation will use a structured data format including customer name, number of guests, and table number. Then, the second feature that we are going to build is a table management system. This feature will enable staff to efficiently track and manage table availability and capacity in real time, ensuring that reservations are allocated correctly. In addition, we are also going to build a waitlist management system, which automatically adds customers to a waiting list when all tables are full. We are also going to integrate the backend system with a MongoDB database, allowing the restaurant to store, retrieve, and update reservation data efficiently. Lastly, at the end of the course, we are going to conduct testing to make sure the systems have been fully functioning and all features are working as intended.

Firstly, before getting into the course, we need to ask this question to ourselves, why should we learn about backend development? Well, here is my answer, the backend is the engine of any application or software, it handles data storage, processes user requests, and enables communication between UI and database, which is what makes the application functional.
