Database migration and synchronization are crucial tasks in development to ensure data consistency and facilitate team collaboration. This article introduces how to use ThinkORM, a lightweight yet powerful ORM framework, to quickly accomplish database migration and synchronization.
Database migration refers to transferring the database structure and data from one environment to another, typically from development to production or between servers. The main goal is to ensure data integrity and consistency.
Data synchronization is the process of maintaining consistent data across multiple databases. It is commonly used for multi-team collaboration or coordinating data among multiple servers, aiming to minimize data conflicts and keep data unified.

from thinkorm import Database
<p>DB = Database({<br>
'default': {<br>
'engine': 'mysql',<br>
'host': 'localhost',<br>
'port': 3306,<br>
'user': 'root',<br>
'password': 'password',<br>
'database': 'test'<br>
}<br>
})

db.create_table(
'users', [
db.column('id', 'integer', primary_key=True),
db.column('name', 'string', length=50),
db.column('email', 'string', length=100),

from thinkorm import Database
<p>DB = Database({<br>
'default': {<br>
'engine': 'mysql',<br>
'host': 'localhost',<br>
'port': 3306,<br>
'user': 'root',<br>
'password': 'password',<br>
'database': 'test'<br>
},<br>
'backup': {<br>
'engine': 'mysql',<br>
'host': 'localhost',<br>
'port': 3306,<br>
'user': 'root',<br>
'password': 'password',<br>
'database': 'backup_test'<br>
}<br>
})
users = DB.table('users').select()
<h1>Data synchronization</h1>
<p>DB.backup.table('users').insert(users)</p>
<h1>Data query</h1>
<p>users_backup = DB.backup.table('users').select()
By following these steps, ThinkORM significantly simplifies database migration and synchronization workflows, improving development efficiency and data stability. Hope this guide helps you master ThinkORM with ease.
