SQLite features and specs

• Zero Configuration
  SQLite does not require any server setup or configuration, allowing for easy integration and deployment in applications.
• Lightweight
  It is extremely lightweight, with a small footprint, making it ideal for embedded systems and mobile applications.
• Self-Contained
  SQLite is self-contained, meaning it has minimal external dependencies, which simplifies its distribution and usage.
• File-Based Storage
  Data is stored in a single file, which makes it easy to manage and transfer databases as simple files.
• ACID Compliance
  SQLite supports Atomicity, Consistency, Isolation, and Durability (ACID) properties, ensuring reliable transactions.
• Cross-Platform
  SQLite is available on numerous platforms, including Windows, MacOS, Linux, iOS, and Android, providing a broad compatibility range.
• Public Domain
  SQLite operates under the public domain, allowing for unrestricted use in commercial and non-commercial applications.

Possible disadvantages of SQLite

• Limited Scalability
  SQLite is not designed to handle high levels of concurrency and large-scale databases, making it less suitable for large, high-traffic applications.
• Write Performance
  Write operations can be slower compared to server-based databases, especially under heavy write loads.
• Lack of Certain Features
  SQLite lacks some advanced features offered by other RDBMS like stored procedures, user-defined functions, and full-text search indexing.
• Security
  As SQLite is file-based, it might lack some of the security features present in server-based databases, such as sophisticated access control.
• Concurrency
  SQLite uses a locking mechanism to control access to the database, which can lead to contention and performance bottlenecks in highly concurrent environments.
• Backup and Restore
  While it's straightforward to copy SQLite database files, it lacks the advanced backup and restore features found in more complex RDBMS.

• Outages and reliability
  The platform has experienced significant outages during periods of high volatility, which can be problematic for active traders.
