In modern application development, the choice of data storage solution is crucial. To meet the needs of different users, Mr.🆖 AI offers flexible configurations that support both local and server-side databases. Whether you prioritize data privacy and control or seek a convenient user experience, Mr.🆖 AI can provide excellent solutions for you.

## Local Database: Data Control and Privacy Protection

For users who prefer more control over their data and value privacy protection, Mr.🆖 AI offers support for local databases. By using IndexedDB as the storage solution and combining it with dexie as an Object-Relational Mapping (ORM) tool, Mr.🆖 AI achieves efficient data management.

Additionally, we have introduced Conflict-Free Replicated Data Type (CRDT) technology to ensure a seamless multi-device synchronization experience. This experimental feature aims to provide users with greater autonomy and data security.

Furthermore, we have attempted to introduce CRDT technology to achieve cross-device synchronization based on the local database. This experimental feature aims to provide users with greater autonomy and data security.

## Server-Side Database: Convenient and Efficient User Experience

For users who seek a convenient user experience, Mr.🆖 AI supports PostgreSQL as the server-side database. By managing data with Dirzzle ORM and combining it with Clerk for authentication, Mr.🆖 AI can offer users an efficient and reliable server-side data management solution.

### Server-Side Database Technology Stack

- **DB**: PostgreSQL (Neon is the default)
- **ORM**: Dirzzle ORM
- **Auth**: Clerk
- **Server Router**: tRPC

## Deployment Solution Selection Guide

### 1. Local Database

The local database solution is suitable for users who wish to have strict control over their data. With Mr.🆖 AI's support for local databases, you can securely store and manage data without relying on external servers. This solution is particularly suitable for users with high requirements for data privacy.

### 2. Server-Side Database

The server-side database solution is ideal for users who want to simplify data management processes and enjoy a convenient user experience. Through server-side databases and user authentication, Mr.🆖 AI can ensure the security and efficiency of data. If you want to learn how to configure a server-side database, please refer to our [detailed documentation](/docs/self-hosting/advanced/server-database).

Whether you choose a local database or a server-side database, Mr.🆖 AI can provide you with an excellent user experience.
