Objection.js features and specs

• Simplicity
  Objection.js provides a simple and intuitive syntax for defining models and relations, making it easy for developers to set up and manage database interactions.
• Flexibility
  It allows for raw SQL queries alongside its ORM capabilities, giving developers the flexibility to optimize and customize queries as needed.
• Powerful Querying
  Objection.js offers powerful querying capabilities with support for eager loading, filtering, and sorting, which are highly customizable and efficient.
• Compatibility with Knex.js
  Objection.js is built on top of Knex.js, allowing developers to leverage the robust query building of Knex.js while benefiting from Objection's ORM features.
• JavaScript and TypeScript Support
  With first-class support for both JavaScript and TypeScript, Objection.js is versatile and can fit into projects using either language.
• Good Documentation
  The library is accompanied by comprehensive documentation, providing detailed guidance and examples for implementation and use.

Possible disadvantages of Objection.js

• Learning Curve
  Despite its simplicity, understanding its full potential, especially for developers new to ORMs, can take time due to its advanced and flexible feature set.
• Dependency on Knex.js
  While leveraging Knex.js is a strength, it also means that any limitations or bugs in Knex.js can directly affect the reliability and functionality of Objection.js.
• Size and Complexity of Projects
  For very simple projects, Objection.js might be considered overkill, providing more functionality than necessary, which can complicate maintenance.
• No Built-in Migration Tool
  Unlike some ORMs, Objection.js does not include a built-in migration tool, requiring developers to use Knex.js migrations or other tools.
• Community and Ecosystem
  While active, the community and ecosystem around Objection.js are not as large as some other popular ORMs, potentially limiting third-party extensions and plugins.

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.
