Storing User Details in Firebase Realtime Database with a Unique UID

When developing an application that requires user data management, it's essential to have a way to uniquely identify each user. Utilizing Firebase Authentication gives you a straightforward way to achieve this by providing a unique User ID (UID) for each authenticated user. In this guide, we’ll explore how to save user details in the Firebase Realtime Database under their unique UID instead of relying on other data like vehicle numbers. Let’s dive right in!

The Problem: Identifying Users

Initially, you might save user data under non-unique identifiers, such as a vehicle number, which can lead to complications and data overwrites if multiple users possess the same vehicle number. Nova's setup can look something like this:

As illustrated in this snippet, the vehicleNo is currently used as the key to store user information. This approach is problematic when multiple users might share the same vehicle number, resulting in data conflicts and loss.

The Solution: Using UID for Unique Identification

Step 1: Fetch the UID

The first step to storing user details securely is to retrieve the current user's unique identifier (UID) from Firebase Authentication. This can be done using the following code snippet:

Step 2: Saving Data with UID

Once you have the UID, you can save the user data under that unique key. Modify your original code as shown below:

Step 3: Confirming Data Storage

To ensure that your data is being saved correctly, you can use Firebase's console or write additional code to fetch the data back to confirm it's stored under the UID.

Key Benefits of Using UID

Uniqueness: Each user has a unique ID, ensuring there's no risk of data overlap.

Data Integrity: Avoids complications with shared identifiers.

Better User Management: Facilitates personalized data retrieval.

Conclusion

By switching to using a unique UID for storing user details in the Firebase Realtime Database, you can provide more reliable data management in your application. This method simplifies user identification and enhances data security. Now every time you add a user, their data is safely linked to their unique identifier, leaving vehicle numbers as potential secondary identifiers within the user's profile.

Implement these changes in your application, and you'll be set for scalable and reliable user data management. Happy coding!
