Why might using a programming language such as C# to interact with an RDBMS seem odd at first?
Why might using a programming language such as C# to interact with an RDBMS seem odd at first?
- Because C# is not suitable for interacting with databases
- Because ORM techniques are not well-established
- Because C# is primarily used for front-end development
- Because RDBMS have their own built-in API for SQL queries (correct)

Study Notes
EF Core Overview
- EF Core is primarily designed for interacting with relational databases through code, simplifying data access in applications.
- ORM stands for Object-Relational Mapping, which EF Core uses to facilitate database operations through objects in programming languages.
Interacting with RDBMS
- Using a high-level programming language like C# to manage a relational database management system (RDBMS) can seem strange since traditional database interactions rely on SQL.
- A key advantage of using an ORM is abstraction, allowing developers to work with objects instead of complex SQL queries, enhancing productivity.
Tradeoffs and Limitations
- A tradeoff of utilizing an ORM is potential performance overhead compared to hand-written SQL, as abstraction layers can add complexity.
- ORMs minimize the need for writing dynamic SQL commands programmatically, significantly reducing the chance for errors in query formulation.
Readability and Learning
- ORM-based statements tend to be more readable, making it easier for developers to understand and maintain code.
- Developers can leverage ORM features, accessing advanced functionalities of databases without needing in-depth SQL knowledge.
Data Retrieval Insights
- A drawback of employing an ORM is the limited ability to inspect low-level data retrieval techniques, which may hide performance implications.
- Utilizing an ORM can facilitate smoother source control, streamlining version management processes within software projects.
General ORM Limitations
- Most ORMs, including EF Core, often have limitations in handling complex queries efficiently, which may require strategic handling.
- Adopting an ORM may spark increased interest in learning SQL among developers as they recognize the limitations and capabilities of the ORM.
Challenges and Benefits
- One challenge in adopting an ORM is the learning curve associated with understanding its concepts and configurations.
- Queries generated by an ORM can demonstrate better optimization compared to those crafted by typical developers, leading to improved performance in some cases.
Code Base Management
- Using an ORM helps minimize the overall complexity of the code base, leading to more streamlined development and easier maintenance.
