How to Create Database and Add in the MVC Application

In MVC application, to store our data for further references, we have to create a database and use that for SQL querying. Earlier we have created the database using Entity Framework that was a code first approach, in this article we will create a Database first and then code to use that.

  • Right click on the App_Data folder and Add New Item.
  • Under Visual C# in left side tree, click on Data node and select SQL Server Database.
  • The default name for the database is Database1 with .mdf file extension and it may change (I have change it StudentDb.mdf). Click on Add to add the database in our application.

As soon as we create this database, our server explorer have a connection with the same as shown.

How to Create Database and Add in the MVC Application

  • Write click on the Table node under newly created database in Server Explorer, and click on Add New Table
  • A design will open with three columns, first for name, second for data type and the last one for Allow nulls or not.
  • Add some Fields in this design as I have added below:

How to Create Database and Add in the MVC Application

While we look in the T-SQL of this table creation, just under the design window i.e.

CREATE TABLE [dbo].[Student]

Change the database name from this T-SQL (Student here) and click on the Update button at left upper of the designer. It will show Preview Database Update window, click on Update Database button and your changes have been saved to database, means Student table have been created in the database.

Add this connection string in your web.config file to establish the connection with the database.

<add name="StudentConnection" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\StudentDb.mdf;Integrated Security=True"/>

The database have been created and added in our project by this connection string, we will do some insert, update and delete with this database in later articles.

difference between structure and union in C Language

In c language article we will see the difference between union and structure. Both are the user define datatype in c language. See the table which is mentioned below: ASP.NET Video Tutorial Series Structure Union1.The keywordstruct is used to define a structure 1. The keyword union is used to define a union. 2. When a variable is associated with a structure, the compiler allocates the memory for each member. The size of structure is greater than or equal to the sum ofsizes of its members. The smaller members may end with unused slack bytes. 2. When a variable is associated with a union, thecompiler allocates thememory by considering the size of the largest memory. So, size of union is equal to the size of largest member. 3. Each member within a structure is assigned unique storage area of location. 3. Memory allocated is shared by individual members of union. 4. The address of each member will be in ascending order This indicates that memory for each member will start at different offset v…

Difference between Linear search and Binary Search in c language

SQL Video Channel : Download all SQL Video

Binary Search Linear Search Works only on sorted items. such as  1,2,3,4,5,6  etc
Works on sorted as well as unsorted items. 12,4,5,3,2,1 etc Very efficient if the items are sorted Very efficient if the items are less and present in the beginning of the list. such as Suppose your list items are : 12,3,4,5,1 and you want to search 12 number then you get beginning in the list. Works well with arrays and not on linked lists. Works with arrays and linked lists.
Number of comparisons are less More number of comparisons are required if the items are present in the later part of the array or its elements are more.

Memory representation of Linked List Data Structures in C Language

Memory representation of Linked List

             In memory the linked list is stored in scattered cells (locations).The memory for each node is allocated dynamically means as and when required. So the Linked List can increase as per the user wish and the size is not fixed, it can vary.

               Suppose first node of linked list is allocated with an address 1008. Its graphical representation looks like the figure shown below:

      Suppose next node is allocated at an address 506, so the list becomes,

  Suppose next node is allocated with an address with an address 10,s the list become,

The other way to represent the linked list is as shown below:

 In the above representation the data stored in the linked list is “INDIA”, the information part of each node contains one character. The external pointer root points to first node’s address 1005. The link part of the node containing information I contains 1007, the address of next node. The last node …
