 Migrating data from MongoDB to Microsoft SQL Server involves multiple steps and typically requires scripting or programming to handle the data extraction, transformation, and loading (ETL) process. Here's an example of Python code that uses the `pymongo` library to connect to MongoDB and the `pyodbc` library to connect to SQL Server for a basic migration: ```python import pymongo import pyodbc # MongoDB connection settings mongo_uri = 'mongodb://username:password@hostname:port/database_name' mongo_client = pymongo.MongoClient(mongo_uri) mongo_db = mongo_client['mongodb_database'] mongo_collection = mongo_db['mongodb_collection'] # SQL Server connection settings sql_server_connection_string = 'Driver={SQL Server};Server=server_name;Database=database_name;Uid=username;Pwd=password' sql_server_connection = pyodbc.connect(sql_server_connection_string) sql_server_cursor = sql_server_connection.cursor() # Query MongoDB data mongo_data = mongo_collection.f

 To sync an offline database to an online MongoDB Atlas database using Realm, you can follow these steps. Realm simplifies the process of data synchronization between your local (offline) database and the cloud database: 1. **Set Up a MongoDB Atlas Cluster**:    - Create a MongoDB Atlas account if you don't have one.    - Set up a cluster in your MongoDB Atlas account to host your cloud database. 2. **Set Up Realm**:    - In your MongoDB Atlas dashboard, navigate to the Realm section.    - Create a new Realm application if you haven't already. 3. **Create a Realm App**:    - Inside your Realm application, create a new Realm app, which will be associated with your MongoDB Atlas cluster. 4. **Define Data Models**:    - Define the data models for your documents in Realm. These data models should match the structure of your MongoDB documents. 5. **Set Up Sync**:    - In your Realm app, set up data synchronization by linking your MongoDB Atlas cluster.    - Define which data to sync
