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.

Dapper features and specs

• Performance
  Dapper is known for its high performance as it uses raw SQL queries and maps results directly to objects, which reduces the overhead of ORM frameworks.
• Lightweight
  It is a micro ORM and thus does not add significant weight to the application. It only requires a single DLL, which is simple to integrate.
• Flexibility
  Dapper provides the flexibility to write complex queries and take full advantage of SQL features, performing tasks that are cumbersome with full ORMs.
• Easy Mapping
  Allows easy mapping of data from the database to C# objects, helping developers handle the conversion between the two seamlessly.
• Open Source and Support
  Dapper is open-source and has a strong community support with regular updates and a wealth of resources available for learning and troubleshooting.

Possible disadvantages of Dapper

• Lack of Built-in Features
  As a micro ORM, Dapper lacks some of the advanced features present in full-featured ORMs like Entity Framework, such as change tracking and full LINQ support.
• Manual SQL Queries
  Developers need to write SQL queries manually, which can increase the risk of SQL injection and bugs if not handled carefully.
• No Automatic Migration
  Unlike some ORMs, Dapper does not offer automatic database migration capabilities, requiring developers to handle schema changes separately.
• Limited Database Support
  While Dapper supports many popular databases, it may not support niche databases or specific features that are easily managed by other ORMs.
