Konva features and specs

• Easy to Use
  Konva provides an intuitive API for creating 2D canvas applications, making it accessible for developers who may not be familiar with complex graphic programming.
• High Performance
  It leverages HTML5's Canvas element for rendering, which allows for efficient drawing operations, making it suitable for developing rich, interactive applications.
• Rich Manipulation Tools
  Konva offers built-in capabilities to easily manipulate and transform shapes, images, and other elements on the canvas, which simplifies the development process.
• Layer and Node System
  The use of layers and nodes helps in organizing complex scenes efficiently and allows for more advanced features, like hit detection and selective rendering, enhancing performance.
• Cross-Platform
  Since Konva is HTML5-based, it works on most modern browsers and can run on both desktop and mobile platforms without compatibility issues.

Possible disadvantages of Konva

• Limited 3D support
  Konva is primarily designed for 2D graphics, and thus lacks built-in support for 3D rendering, which might be a limitation for developers needing 3D capabilities.
• Performance on Older Devices
  While Konva is quite performant, running complex scenes or high volumes of objects may lead to performance bottlenecks, especially on older hardware.
• Learning Curve for Advanced Features
  Even though it's easy to start with, leveraging Konva's full potential requires understanding its more advanced features and concepts, which may take time for new users.
• Dependency on Third-party Libraries
  Advanced functionality may require additional integration with other JavaScript libraries which can increase project complexity and dependency management.
• Limited Built-in UI Components
  Unlike some UI frameworks, Konva does not offer a wide array of pre-built UI components, which could require additional implementation effort for standard elements.

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.
