Introduction
ORM or Object Relational Mapping will help you directly map your database with the C# objects. Several ORM tools are available out there. And among all of them, Dapper is the most popular tool.
Most of the user requirements are fulfilled through Dapper. It makes things easier for the developers and the users, save time, and facilitates several complicated processes.
In this article, we've enumerated everything about Dapper ORM that you will need to know when implementing tools for mapping databases.
Let’s dig in!
What Is Dapper?
Dapper describes itself as a micro-ORM. In short, it is a simple framework that facilitates object mapping. With the help of Dapper, the native query output can be mapped to a C# or domain class. Dapper being a high-performance system facilitating data access, is released as an open-source.
If there is the involvement of writing down native queries or stored procedures, Dapper is the ideal choice for your purpose. By making use of Dapper, a SQL query can be fired against a database, and the result mapped to the C# domain class can be received.
Dapper also enables the users to retrieve entity objectives straight from the relational tables. When you are using Dapper, you are only obliged to add the functionality/library that you require
- Dapper is lightweight and fast, making it an ideal choice for applications that require low latency and high performance.
- Dapper is a simple yet powerful object mapping tool for any .NET language, such as C#, that enables developers to quickly and easily map query results from ADO.NET data readers to instances of business objects.
- Dapper has excellent support for both asynchronous and synchronous database queries and batching multiple queries together into a single call.
Features Of Dapper
Some of the significant features of Dapper are described below:
- It is super speedy and offers super-fast performance and smoothness.
- Only needs a few lines of code.
- Facilitates static object binding, dynamic object binding, and object mapper.
- The SQL query and stored procedure can be easily handled.
- It has support for multiple queries and stored procedures.
- The functionality of inserting bulk data is also there.
- Dapper also allows you to fetch distinct data based on distinct inputs.
Why Use Dapper?
The reasons for using Dapper are as follows:
- Among all the ORMs, Dapper is considered to be the 2nd fastest one.
- CRUD operations can be performed directly by making use of the IDBConnection object.
- Dapper offers to query both dynamic and static data over the database.
- You can receive generic results for both complex or simple types of data.
- The best thing about Dapper is that it allows you to store your bulk data at once.
There are three major steps that you need to follow for making dapper works:
Step 1: An IB connection needs to be created with the help of the connection string.
Step 2: You will have to write down a query, and then it needs to be stored in a general string variable.
Step 3: Then you will have to Call db.execute(), and then the query needs to be passed. And finally, you are all done.
Advantages of Using Dapper ORM
Dapper ORM is an open-source solution, highly compatible with the .NET application framework, which lets one constantly work on strongly typed data without struggling to write the codes for hours.
Dapper ORM’s capability to manage codes and dealing with unnormalised databases, it also comes with following benefits:
- Dapper ORM provides in-built mapper objects.
- Gives peak performance with its lightweight nature and lack of overhead.
- Execute and control raw SQL queries.
- Solves multiple queries and supports bulk data at single time.
- Easily use stored procedures.
Dapper ORM Supports
Dapper - Object Mapper
Dapper ORM lets you map your application code to your relational database. In run-time, data will be retrieved from the database and filled into the object model.
Dapper also provides support for multi-mapping, which allows you to map a single record from one database table to multiple records from another table. With Dapper ORM mapping you can retrieve data from multiple database tables in one query.
Which Is Better: Dapper or Entity Framework?
Entity Framework and Dapper are two popular Object-Relational Mapping (ORM) tools used in .NET applications.
While both serve the purpose of simplifying data access and mapping between objects and the database, they have different approaches and features.
Though, it depends. If you have an application where data access performance is absolutely paramount and your development team is filled with individuals with strong SQL skills then perhaps Dapper ORM would be the better choice. If you're willing to concede that you won't get the absolute best performance, you're looking for potentially faster development time, or you don't have a lot of skilled SQL developers on your staff, then Entity Framework Core might be the best choice.
Conclusion
So, to finally conclude, we can say that Dapper is a great utility tool and can make things a lot easier for users. It makes things easy for correctly parameterizing the queries, and any queries can be easily executed by it. It also makes things easy for returning results to the objects.
Dapper is efficient, and it is still being explored. So, in the future, dapper is expected to offer more advantages and utilities.
