MyBATIS features and specs

• Simplicity
  MyBatis is easier to use compared to other ORM tools because it provides a simple and direct approach to database interaction using XML or annotations, making it accessible for developers familiar with SQL.
• Flexibility in SQL
  It allows for complete control over SQL queries, enabling developers to write complex queries and use full SQL syntax without constraints, unlike automated ORM solutions.
• Performance
  Since developers have direct control over SQL statements, the performance can be optimized for specific use cases, potentially reducing the overhead that automated ORM solutions might introduce.
• Mapping
  Offers robust and customizable mapping capabilities between database tables and Java classes, helping in clearly defining how data should be transformed between the system and the data layer.
• Lazy Loading
  Supports lazy loading of related objects, which can improve performance by delaying the fetching of data until it is specifically needed.

Possible disadvantages of MyBATIS

• Manual SQL Management
  The need to manually write and maintain SQL can be cumbersome and error-prone, especially for complex applications with large numbers of queries.
• Lack of Automated Associations
  MyBatis does not inherently manage relationships between entities like some other ORM tools, which requires developers to handle association mappings themselves.
• Limited Abstraction
  Compared to full ORM frameworks, MyBatis offers less abstraction over the database layer, which means developers must handle more of the database logic manually.
• Learning Curve for XML
  While not steep, there is a learning curve involved in configuring MyBatis using XML for those who are more accustomed to purely annotation-driven configuration or other ORM tools.
• Reduced Portability
  Because SQL is database-specific, MyBatis applications might become less portable across different database platforms when relying extensively on custom SQL.

DBFlow features and specs

• ORM Capabilities
  DBFlow provides full-featured ORM capabilities, allowing developers to easily manage database operations using Java or Kotlin objects, which simplifies database interactions.
• Complex Query Support
  The library supports complex database queries, including joins and transactions, enabling developers to perform intricate data retrieval and manipulation tasks.
• Migration Support
  DBFlow offers support for database migrations, making it easier to upgrade database schema without losing existing data, which is crucial for app version updates.
• Active Community
  DBFlow has an active community and comprehensive documentation, allowing users to quickly find solutions to common problems and stay updated with the latest features.
• Annotation-Based Configuration
  The library uses annotations to simplify configuration and reduce the amount of boilerplate code needed for database setup and maintenance.

Possible disadvantages of DBFlow

• Learning Curve
  For developers new to ORMs or coming from simpler database solutions, DBFlow’s extensive feature set and configuration options may present a steep learning curve.
• Performance Overhead
  As with many ORMs, DBFlow may introduce some performance overhead compared to direct SQLite queries, which can be a concern for performance-critical applications.
• Project Maintenance
  With ORM libraries, including DBFlow, there is always the risk of reduced maintenance or updates, which can be problematic if the project does not receive regular support and improvements.
• Limited Control Over SQL
  While DBFlow supports complex queries, developers may find the abstraction limits their control over raw SQL, which can be necessary for highly optimized queries.
• Dependency Management
  Integrating DBFlow involves adding additional dependencies to your project, which can complicate dependency management and increase the size of the final application binary.
