NHibernate features and specs

Rich ORM Features
NHibernate provides comprehensive Object-Relational Mapping (ORM) capabilities, allowing developers to easily map .NET objects to database tables, manage relationships, and perform complex queries.
Database Independence
NHibernate abstracts database interactions, enabling support for multiple databases with minimal changes to the data access layer. This is beneficial for applications that need to support different database platforms.
Advanced Querying
Supports both criteria queries and HQL (Hibernate Query Language), which allow for complex and dynamic query capabilities, providing more flexibility in how data is retrieved.
Lazy Loading
Offers lazy loading of data, improving application performance by only loading objects when they are specifically requested by the application logic.
Active Community and Extensions
Having a strong community and many extensions, NHibernate provides a wealth of resources, plugins, and extensions to enhance its functionality and ease of use.

Possible disadvantages of NHibernate

Steep Learning Curve
Due to its comprehensive features and capabilities, NHibernate can be complex and may have a steep learning curve for new developers, requiring significant time to master.
Performance Overhead
The abstraction layer introduced by NHibernate, while beneficial for flexibility and ease of development, can add performance overhead compared to direct database access.
Complexity in Mapping Configuration
Configuring mappings of complex object models to database schemas can be challenging, and errors in configuration can lead to runtime issues.
Less Support for Modern .NET Features
Compared to newer ORM tools like Entity Framework Core, NHibernate may lag in supporting some of the latest .NET features and syntactic sugar, affecting developer efficiency.
Documentation Quality
While NHibernate has extensive functionality, the documentation can sometimes be lacking in clarity and completeness, posing difficulties for developers when troubleshooting issues.

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.

Introduction to Object-Relational Mappers (ORMs)
Documentation: NHibernate Documentation. - Source: dev.to / 9 months ago
Building business processes with Azure Durable Functions
Traditionally, building business processes involves a highly database-centric approach. Development typically begins with a comprehensive database design, setting up schemas and tables before moving on to create classes and properties. These classes would then map to the database schema using Object-Relational Mappers (ORMs) like Entity Framework, NHibernate or Dapper. This method, while effective, often leads to... - Source: dev.to / 12 months ago

Guys, where do you shop for reasonably priced everyday office shoes?
I've also heard good things about Thursday but never pulled the trigger. I tend to like Timberland boots, and while they aren't the most long-lasting, they are comfortable and can be had for very cheap if you wait for sales. I also have a pair of Banana Republic boots that I bought in a pinch a few years ago that have held up remarkably well and are super comfy. But Banana has gone through several revamps since...
