An embedded database is a database management system that is integrated within an application rather than being a standalone system. This means that the application has direct control over the database, and the database runs within the same process as the application. Embedded databases are often used in applications where data needs to be stored and accessed locally, without the need for a separate database server.

Embedded database

Embedded databases are typically used when an application needs to store data locally and the data is not shared with other applications or users. They are often used in desktop and mobile applications, as well as in embedded systems such as IoT devices, where network connectivity may be limited or unreliable.

Some common examples of embedded databases include SQLite, H2 Database, Berkeley DB, and Firebird. These databases are often lightweight, fast, and efficient, making them ideal for use in applications with limited resources. They may also include features such as ACID transactions, replication, or full-text search, depending on the specific needs of the application.

When to use one?

Embedded databases are typically used when an application needs to store data locally and the data is not shared with other applications or users. They are often used in desktop and mobile applications, as well as in embedded systems such as IoT devices, where network connectivity may be limited or unreliable.

One popular embedded database that deserves special mention is Watermelon DB. Watermelon DB is an open-source, reactive database that is designed specifically for use in client-side applications. It provides a fast and reliable way to store data locally, with built-in support for offline data synchronization.

Watermelon DB is ideal for use in mobile and web applications that need to work offline. It uses a data synchronization protocol called Differential Synchronization, which allows the database to synchronize with a remote server while minimizing bandwidth usage and reducing conflicts. Watermelon DB is also highly scalable, making it suitable for use in applications with large and complex data models.

Some common use cases for embedded databases include:

● Desktop and mobile applications that need to store data locally.

● IoT devices that need to store sensor data locally.

● Point-of-sale systems that need to store transaction data locally.

● Gaming applications that need to store game data locally.

● Medical devices that need to store patient data locally.

Popular Embedded databases:

SQLite: A lightweight, open-source database that is widely used in mobile and desktop applications.

H2 Database: A Java-based database that is designed to be fast and efficient.

Berkley DB: A high-performance, embeddable database that is used in a wide range of applications.

Firebird: An open-source relational database that is used in embedded systems and desktop applications.

Embedded databases and its feature

How to choose the correct embedded database?

Choosing the correct embedded database for your application depends on a number of factors, such as the size and complexity of the application, the performance requirements, and the desired features. Here are some steps you can follow to choose the right embedded database for your needs:

· Identify the requirements of your application: Determine what kind of data needs to be stored and how it will be accessed, as well as any performance or scalability requirements.

· Consider the size of the database: Depending on the size of your application and the amount of data you need to store, you may need to choose a database that is lightweight and efficient. Look for databases that have a small footprint and use minimal system resources.

· Evaluate the performance: Consider the performance characteristics of the database, such as query times and transaction processing speeds, to ensure that it meets your requirements.

· Look for required features: Determine which features are essential for your application, such as support for ACID transactions, replication, or full-text search. Make sure the database you choose includes these features.

· Check the licensing: Some embedded databases have more restrictive licenses than others. Make sure the license of the database you choose is compatible with your application’s requirements and licensing model.

Embedded databases are an important component in many desktop and mobile applications, as well as in embedded systems such as IoT devices. These databases provide a lightweight and efficient way to store data locally without the need for a separate database server.
