  • To avoid OS that will ignore cases, database name should use snake_case. And collections name I could use upper camel case and field name in lower camel case?

• ChatGPT

  • Yes, using a consistent and clear naming convention like the one you suggested can help avoid issues with case sensitivity across different operating systems and ensure readability. Here’s a summary of the recommended naming conventions based on your criteria:

• Naming Conventions:

  • Databases: Use snake_case.
  • Collections: Use UpperCamelCase.
  • Fields: Use lowerCamelCase.

• Examples:

  • Databases:
    • sales_data, user_profiles
  • Collections:
    • UserProfiles, OrderDetails
  • Fields:
    • firstName, lastName, orderDate

• Practical Examples:

// Access the sales_data database
use sales_data

// Access the UserProfiles collection within the sales_data database
db.UserProfiles.find()
{
  "firstName": "John",
  "lastName": "Doe",
  "orderDate": "2024-06-01",
  "orderDetails": {
    "productId": "12345",
    "quantity": 2,
    "price": 19.99
  }
}

• Summary of Guidelines:
  • Databases:
    • Use snake_case to ensure compatibility across different systems and avoid case sensitivity issues.
    • Example: user_profiles, sales_data.
  • Collections:
    • Use UpperCamelCase to distinguish collections from databases and fields clearly.
    • Example: UserProfiles, OrderDetails.
  • Fields:
    • Use lowerCamelCase for fields to maintain a consistent and familiar naming style within documents.
    • Example: firstName, lastName, orderDate.

By following these conventions, you ensure that your database schema is clear, consistent, and less prone to errors related to case sensitivity across different operating systems.

• Final Recommendation:
  • For databases: Use snake_case (e.g., user_profiles, order_details).
    • Do not rely on case to distinguish between databases, so avoiding using camel cases
  • For collections:
    • user_profiles instead of user-profiles.
      • or, Use userProfiles or
  • For fields: Use camelCase(lower) (e.g., firstName, orderDate).

db.sales_data.user_profiles.find()
db.sales_data.order_details.find()

{
  "firstName": "John",
  "lastName": "Doe",
  "orderDate": "2024-06-01"
}
