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.

JDBI features and specs

• Simplicity
  JDBI provides a simple, fluent API that makes accessing relational databases in Java more streamlined and less error-prone than using plain JDBC.
• SQL-centric Approach
  JDBI allows developers to work directly with SQL, offering the flexibility to use any SQL feature without abstraction limitations.
• Ease of Integration
  JDBI is easy to integrate into existing projects and works seamlessly with various database systems.
• Declarative Mapping
  It supports declarative and annotation-based data mapping, reducing boilerplate code when converting between database rows and Java objects.
• Extensibility
  JDBI's plugin architecture allows developers to extend its capabilities easily with custom features or integrate with other libraries.

Possible disadvantages of JDBI

• Limited Abstraction
  Compared to full-fledged ORM frameworks, JDBI provides less abstraction, which could be a drawback for applications requiring complex entity relationships.
• Manual Resource Management
  Developers need to manage database connections and resources, increasing the risk of resource leaks if not handled properly.
• Less Mature than Some ORMs
  Although reliable, JDBI may not have the maturity or widespread adoption of some older ORMs, potentially resulting in less community support.
• Learning Curve
  For developers used to traditional ORM frameworks, learning JDBI's idiomatic ways to achieve similar tasks might require an adjustment period.
