How to develop a simple online reservation system using Go language

Introduction: With the rapid development of the Internet, various online service platforms have also emerged. Among them, the reservation system for offline service venues has become one of the necessary tools for many businesses. This article will introduce how to use Go language to develop a simple online reservation system to help merchants better manage reservation orders.

1. Demand analysis

1. Merchant client:
   a. Login/Registration: Merchants need an account to manage reservation orders.
   b. Create reservation places and services: Merchants can create reservation places and corresponding services. For example, restaurants can create tables and dishes, and beauty salons can create barber chairs and beauty items.
   c. View reservation orders: Merchants can view reservation orders and process the orders.
   d. Modify the reservation time: Merchants can modify the reservation time of orders that have been reserved.
   e. Cancel reservation: Merchant can cancel the order that has been reserved.
2. Customer client:
   a. Reservation venues and services: Customers can browse the reservation venues and services created by the merchant, and select the ones they like to make a reservation.
   b. Select an appointment time: Customers can choose a suitable appointment time.
   c. Submit an appointment order: Customers need to fill in their contact information and submit an appointment order.
   d. View reservation orders: Customers can view the orders they have reserved.
   e. Cancel reservation: Customers can cancel the order that has been reserved.

2. System design

1. Database design:
   a. Merchant table: stores merchant user information, including merchant ID, user name, password, etc.
   b. Reservation venue table: stores reservation venue information created by merchants, including venue ID, venue name, merchant ID, etc.
   c. Service item table: stores service item information created by merchants, including project ID, project name, location ID, etc.
   d. Reservation order table: stores reservation order information, including order ID, customer ID, location ID, project ID, reservation time, etc.
   e. Customer table: stores customer user information, including customer ID, user name, password, etc.
2. Back-end development:
   a. Use Go language to write the back-end interface, including user login/registration, merchants creating reservation places and service items, merchants viewing/modifying/cancelling reservation orders, and customer reservation/cancellation Reservation order and other interfaces.
   b. Use Go language to operate the database and store user and order information in the database.
   c. Use a third-party library for identity verification and password encryption to ensure the security of user information and orders.
3. Front-end development:
   a. Use HTML, CSS and JavaScript to develop front-end pages, including login/registration of merchant client and customer client, reservation venue and service item display, reservation order management and other pages.
   b. Use Ajax to request the backend interface to obtain data, and update the page content through DOM operations.
   c. Use front-end frameworks such as Bootstrap to improve the aesthetics and responsiveness of the interface.

3. System implementation

1. Build a development environment: Install the Go language development environment and database, and import related third-party libraries.
2. Database table creation: Create corresponding data tables based on the database design in the requirements analysis.
3. Develop back-end interface: According to the needs of merchants and customers in the demand analysis, write the corresponding back-end interface to implement the functions of adding, deleting, modifying and checking data and processing reservation orders.
4. Develop front-end pages: According to the needs of merchants and customers in the demand analysis, write corresponding front-end pages to realize user login/registration, reservation venue and service item display, reservation order management and other functions.
5. Debugging and testing: Conduct debugging and testing in the local environment to ensure system stability and functional correctness.
6. Deployment and online: Deploy the system to the server for use by merchants and customers.

Conclusion: By using Go language development, we can quickly and efficiently develop a simple online reservation system to help merchants better manage reservation orders and improve users' reservation experience. However, this is just a simple example system, and more functions and security need to be considered in actual applications, such as payment functions, password encryption, preventing malicious reservations, etc. I hope this article can provide some reference and guidance for beginners in Go language development and online reservation systems.
