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.

DuckDB features and specs

• Lightweight
  DuckDB is a lightweight database that is easy to install and use without requiring a separate server process.
• In-Memory Processing
  It supports efficient in-memory execution, which makes it suitable for analytical queries that require quick data processing.
• Columnar Storage
  DuckDB uses a columnar storage format that optimizes for analytical workloads by improving read performance for large datasets.
• Integration with Data Science Tools
  The database integrates well with popular data science tools and libraries such as Pandas, R, and Jupyter Notebooks.
• SQL Support
  DuckDB offers full support for SQL, allowing users to leverage their existing SQL knowledge without having to learn new query languages.
• Open Source
  DuckDB is open-source, enabling users to inspect the code, contribute to its development, and use it without licensing costs.

Possible disadvantages of DuckDB

• Limited Scalability
  DuckDB is optimized for single-node operations, which may not be suitable for scaling out to large, distributed data workloads.
• Relatively New
  As a newer database system, DuckDB might lack some features and optimizations found in more mature database systems.
• Lack of Advanced Features
  DuckDB may not support some advanced database management features like complex transactions and user permissions found in other database systems.
• Community and Support
  Being a less mature project, it might not have as large a community or extensive documentation and support as other established database systems.
• Limited Distributed Processing
  DuckDB currently focuses more on local data processing and may not be the best choice for applications needing distributed computing capabilities.
