SQL Server Integration with .NET Framework: Introduction to SQL

The .NET Framework is a collection of services and classes and exists as a layer between the .NET applications and the underlying operating system. SQL Server uses various services provided by the .NET Framework. For example, the notification services component is based on the .NET Framework and uses its services to generate and send notification messages.

SQL Server is integrated with the .NET Framework, as shown in the following figure.

SQL Server Integration with .NET Framework: Introduction to SQL

Advantage of the .NET integration is that you can create managed database objects. Managed database objects are created by using any .NET language and can be embedded within the SQL Server. For example, developers can create an object that retrieves data from a Web server and saves it in a database table. This provides the software developer with a flexibility of writing codes in a language the developer is most comfortable with. Therefore, as a database developer, it is important to understand the .NET Framework.

The .NET Framework

The .NET Framework is an environment used to build, deploy, and run business applications. These applications can be built in various programming languages supported by the .NET Framework.

The .NET Framework is designed to make significant improvements in code reuse, code specialization, resource management, Multilanguage development, security, deployment, and administration. Therefore, it helps bridge the gap of interoperability between applications.

The .NET Framework consists of the following components:

  • Development tools and languages
  • Base Class Library
  • Common Language Runtime (CLR)

Development Tools and Languages

The development tools and languages are used to create the interface for the Windows forms, Web forms, and console applications. The development tools include Visual Studio 2005 and Visual C# Developer. The languages that can be used are Visual Basic .NET, C#, or J#. These components are based on the .NET Framework base classes.

Base Class Library

The .NET Framework consists of a class library that acts as a base for any .NET language, such as Visual Basic, .NET, and C#. This class library is built on the object-oriented nature of the runtime. It provides classes that can be used in the code to accomplish a range of common programming tasks, such as string management, data collection, database connectivity, and file access.

CLR provides an environment for the application to run, discussed in next article.

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 …
