Retrofit features and specs

• Easy to Use
  Retrofit provides a simple and intuitive API for making HTTP requests, making it easy to integrate with your Android applications.
• Type-Safe HTTP Calls
  With Retrofit, HTTP requests are made using method calls, and responses are automatically converted to Java objects. This type safety helps reduce errors in making network calls.
• Flexible and Extensible
  Retrofit supports a variety of converters (like Gson, Jackson, Moshi, Protobuf), adapters (like RxJava, Kotlin Coroutines), and other customizations, making it highly adaptable to various needs.
• Annotation-Based Configuration
  Annotations like @GET, @POST, and @Query make defining APIs more declarative and concise, reducing boilerplate code.
• Built-In Support for Pagination
  Retrofit's integration with libraries like Paging makes it straightforward to implement paginated data loading.
• Integration with OkHttp
  Retrofit seamlessly integrates with OkHttp, which provides caching, connection pooling, and HTTP/2 support, thus enhancing performance and reliability.

Possible disadvantages of Retrofit

• Learning Curve
  While easy to use, it has some initial learning overhead, especially for developers not familiar with annotation-based configuration and asynchronous programming.
• Verbose Error Handling
  Error handling in Retrofit can be verbose and repetitive if not done correctly, requiring custom solutions for efficient handling of common HTTP errors.
• Larger APK Size
  Including both Retrofit and its dependencies, such as OkHttp and various converters, can increase the size of your APK, which might be a concern for developers optimizing for smaller app sizes.
• Complex Configuration for Advanced Use Cases
  For more complex scenarios like custom request/response logging, interceptors, and parsers, configuration can become cumbersome and less straightforward.
• Default Lack of Built-In Caching
  While OkHttp supports caching, Retrofit does not provide built-in caching out of the box. This requires additional configuration to implement client-side caching effectively.
• No Built-In WebSocket Support
  Retrofit is mainly designed for RESTful APIs and does not natively support WebSocket communication, requiring additional libraries for such use cases.

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.
