Design the database as shown below:
Now, Add a new ADO.NET Data Model, From the Model Folder
Click on Add
Click on Next
Click on New Connection
Click on Test Connection. Once the test connection is success
Click on Ok Button
Click on Next Button
Click on Next Button, Select the table Name on which you want to do CRUD Operations
Click on Finish Button
Now, we need to Add Angular Js Plugin
Click on Install Button
Once Installed you can see in the script folder
Now, we will Add a EmployeeController and Add the below code
EmployeeController:
public class EmployeeController : Controller
{
// GET: Employee
public ActionResult Index()
{
return View();
}
/// <summary>
/// This method is used to Get the Details of the Employee
/// </summary>
/// <returns>JSONRESULT</returns>
public JsonResult GetEmployeeDetails()
{
using (MYDBEntities Obj = new MYDBEntities())
{
List<EMP> Emp = Obj.EMPs.ToList();
return Json(Emp, JsonRequestBehavior.AllowGet);
}
}
/// <summary>
/// Insert an Employee
/// </summary>
/// <param name="Employe">emp</param>
/// <returns>String</returns>
[HttpPost]
public string InsertEmployee(EMP Employe)
{
if (Employe != null)

using (MYDBEntities Obj = new MYDBEntities())
{
Obj.EMPs.Add(Employe);
Obj.SaveChanges();
return "Employee Added Successfully";
}
}
else
{
