   MS SQL Server is well-known for its dependability and resilience. It includes solutions for high availability and disaster recovery such as database mirroring, log shipping, and failover clustering. These features reduce downtime and guarantee that important company operations run smoothly.

Advanced-Data Management Features

   MS SQL Server provides a wide range of advanced data management tools. It supports sophisticated data types like geographic and XML data and gives robust tools for interacting with various data kinds. It also includes Before we go into the advantages, let’s first define MS SQL Server. MS SQL Server is a relational database management system (RDBMS) designed to store, manage, and retrieve structured data. It provides a secure and scalable framework for programs to interface with the underlying database. MS SQL Server provides a stable working environment for developers and administrators thanks to its extensive set of capabilities and tools. Partitioning, compression, and data deduplication are examples of features that optimize storage and increase overall database performance.

Compatibility and Integration

   MS SQL Server works smoothly with other Microsoft products and technologies, including the.NET framework, Azure services, and Microsoft Power BI. It also supports a variety of data access protocols, such as ODBC, OLE DB, and ADO.NET, allowing it to be used with a wide range of applications and computer languages.

Simplified Development and Administration

   MS SQL Server makes database development and administration easier. SQL Server Management Studio is a user-friendly graphical interface for managing databases, establishing security, and composing queries. It also supports strong programming languages such as T-SQL, which allows developers to create robust and efficient database applications.

Analytics and Business Intelligence

   MS SQL Server provides robust business information and analytics features. SQL Server Analysis Services (SSAS) for multidimensional analysis and SQL Server Reporting Services (SSRS) are included.

SSRS) to generate interactive reports. It also connects with Microsoft Power BI, allowing organizations to better visualize and analyze data.

Business Intelligence and Analytics

   MS SQL Server offers cost-effective database management solutions. It provides a variety of licensing choices, including free versions for smaller applications and cost-effective options for enterprise-level installations. Furthermore, robust documentation, online resources, and a huge user community lower the cost of training and support.

Real-World Examples of Benefits of Using MS SQL Server

Let’s look at some real-world examples to better grasp the benefits of MS SQL Server:

E-commerce Platform

   MS SQL Server is used for data storage and processing on an e-commerce platform with thousands of daily transactions. The platform takes advantage of MS SQL Server’s scalability and performance, ensuring quick and reliable retrieval of product information and order processing.

Healthcare System

   Using MS SQL Server, a healthcare system controls patient records, appointments, and medical history. The system’s data integrity features ensure that patient information stays correct and safe, while its robustness ensures that essential medical data is accessible at all times.

Financial services

SQL Server is used by financial services organizations to store customer data, account data, and transaction data. This information can be used to manage risk, track performance, and ensure compliance with rules.

Manufacturing

SQL Server is used by manufacturers to store product data, inventory data, and production data. This information can be used to increase efficiency, reduce costs, and satisfy client demand.

A database with duplicate records can be very problematic for your application. They may produce inaccurate results, use storage space, and impair the functionality of the application. Due to this, it’s crucial to be able to rapidly and effectively detect and get rid of duplicate records.

Introduction

For .NET developers, Entity Framework is a potent Object-Relational Mapping (ORM) tool. It may assist you with operations like querying, updating, and removing data in a database and enables you to work with databases using strongly-typed.NET objects. This post will concentrate on using Entity Framework to identify and get rid of redundant records in a database.

Understanding Duplicate Records

When two or more rows in a database table have the same values for every column, duplicate entries are created. Multiple things, including data entry errors, software problems, and hardware issues, might result in duplicate records. Duplicate records might make it harder for your application to acquire accurate data from the database, which can lead to issues.

Install Required Software

• NET Core SDK from here
• Visual Studio or Visual Studio Code from here

Setup the Project

Make sure we have a functioning ASP.NET Core project with Entity Framework installed before we begin. You can start a new project in Visual Studio or by using the dotnet new command if you don’t already have one.

Add the Entity Framework Core package to your project once it has been configured. Run the following command in the Package Manager Console to accomplish this:

Install-Package Microsoft.EntityFrameworkCore

Find Duplicate Records Using Entity Framework in Asp.net Core

In Entity Framework, there are numerous methods for locating duplicate records. Below, we’ll look at a few of the more popular techniques.

Sample Data

 List<Employee> Employees = new List<Employee>
        {
         new Employee{ EmpId= 1, FirstName = "Vicky",LastName= "Pointing" },
         new Employee{ EmpId= 2, FirstName = "John",LastName= "Astle" },
         new Employee{ EmpId= 3, FirstName = "Vicky",LastName= "Pointing" },
         new Employee{ EmpId= 4, FirstName = "Fleming",LastName= "Mick" },
         new Employee{ EmpId= 5, FirstName = "Vicky",LastName= "Pointing" },
         new Employee{ EmpId= 6, FirstName = "Jonty",LastName= "M" },
         new Employee{ EmpId= 7, FirstName = "Vicky",LastName= "Pointing" },
         new Employee{ EmpId= 8, FirstName = "Fleming",LastName= "Mick" }
        };

Group By

The GroupBy approach is one way to identify duplicate records. Based on a given key, this method groups the table’s rows and returns the groups as a collection. We can group the rows by the columns we want to check for duplicates in order to discover duplicate records, and then filter the groups that contain more than one row.

   public IActionResult Index()
        {

            var Employee = Employees.GroupBy(d => new { d.FirstName, d.LastName })
                .Where(g => g.Count() > 1).Select(g => new { g.Key.FirstName, g.Key.LastName });

            ViewBag.DupRecord = Employee;

            return View();
        }
    }

According to columns FirstName and LastName, the rows in the Employee table are grouped by this code, which then filters the groups with more than one row. A list of groups with duplicate records is the outcome.

Using Any

The Any approach is an additional technique for locating duplicate entries. If any element in a sequence matches a given criterion, this method returns true. We can use the Any method to see if any rows in a table meet the requirements for duplicate records in order to find duplicate records. Here’s an illustration:

  public IActionResult Index()
        {
 
             var dupemployee = Employees.GroupBy(d => new { d.FirstName, d.LastName })
               .Any(g => g.Count() > 1);                

            

            return View();
        }

The Any method is used to determine whether any groups of rows in the Employee table that are grouped by Columns FirstName and LastName have more than one row. The outcome is a boolean value that denotes if the table contains duplicate records.

Conclusion

In this post, we looked at numerous methods for finding duplicate records in ASP.NET Core using Entity Framework. You can quickly and efficiently detect and eliminate duplicate records in your database by using the methods outlined here. This will help to ensure that your application functions properly and gives accurate data to your users.
