Summary
Vercel Postgres is a serverless SQL database optimized for seamless integration with Vercel Functions and frontend frameworks. It is secure, highly scalable, and well-suited for real-time data, complex transactional data, and diverse data formats. Vercel Postgres is powered by a partnership with Neon and available in beta on Pro and Hobby plans.

Facts

💾 Ideal for complex, transactional data, Postgres ensures high consistency and concurrency, making it ideal for storing financial transactions, inventory records, or critical data.

🔄 Offers rich data types and extensibility, making it suitable for handling JSON, arrays, user-generated content, or custom data types.

🖥️ You can access your database with any PostgreSQL client or ORM and have multiple Vercel Postgres databases per account and project.

🏥 Vercel Postgres should not be considered SOC 2 Type 2 compliant during the public beta.

🔋 When creating a database, we recommend choosing the region that matches your Serverless and Edge Functions to increase response time.

🤖 Vercel recommends using Vercel Postgres with an ORM for larger applications and provides templates for Kysely, Prisma, and Drizzle.

💡 Vercel Postgres databases can be scoped to different environments within projects using Environment Variables.

Summary
URB is a universal railway bus project that allows for control of any electronic device on your layout using an Android app and Arduino hardware. There are no restrictions on the number of devices or the size of your layout, and it allows for easy updates and integration with other equipment.

Fact

📱 The project includes an Android app for control of electronic devices on your railway layout.

👨‍💻 The protocol rules for applying and writing Arduino Sketches are included.

🔌 Data exchange between the layout and the application is carried out through Bluetooth or Serial connection.

💡 The system allows for control of lighting and other mechanical devices such as a lifting device for a bridge.

🌟 Reprogramming of Arduino allows for infinite possibilities for updating the layout.

🌉 Real interlocking can be built into the system.

🚂 The connection of any type of signal, sensor, or other element of the railway infrastructure is already integrated into the project.
