Possible disadvantages of Preply

• Quality Variability
  With a wide range of tutors, the quality of teaching can vary significantly, which may require students to try multiple tutors before finding a suitable one.
• Platform Fees
  Preply charges a commission fee on each lesson, which can make the overall cost higher than if you were to pay a tutor directly.
• Cancellation Policies
  The cancellation policy may vary from tutor to tutor, and some may have strict rules that can lead to loss of payment if lessons are canceled last minute.
• Potential Communication Barriers
  Given the global network of tutors, language barriers or differing communication styles can sometimes be an issue.
• Limited In-Person Interaction
  As an online platform, it lacks the face-to-face interaction that some learners may prefer for more effective learning.
• Dependence on Technology
  Lessons conducted online require reliable internet access and adequate technology, which may be a limitation for some users.

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.
