  • Students know the importance of surrogate keys. In this session students will learn the strategy to generate the surrogate key. Give an example to explain the strategy to generate the surrogate keys by concatenating the primary key of the source table with the date stamp. For example, data from a Product table has to be loaded into the Product_Dim dimension table on Feb 09, 2006. The product_code is the primary key column in the Product table. To insert the surrogate key values before loading the data into the dimension table, you can combine the primary key value with the date on which the data has to be loaded. In this case the surrogate key value can be product_code+09022006.

    1. 1. Object-Oriented Programming Using C#Objectives In this session, you will learn to: Use static variables and static functions Identify the components of the .NET Framework Use the Visual Studio .NET IDE Ver. 1.0 Session 5 Slide 1 of 35
    2. 2. Object-Oriented Programming Using C#Static Variables and Static Functions Each object has its own set of member variables. To retain the value of a variable throughout the program, you can declare the variable as a static variable. To manipulate and use the values of static variables, you can define a function as static function. Ver. 1.0 Session 5 Slide 2 of 35
    3. 3. Object-Oriented Programming Using C#Static Variables • The keyword static means that only one instance of a given variable exists for a class. • Static variables are used to define constants because their values can be retrieved by invoking the class without creating an instance of it. • Static variables can be initialized outside the member function or class definition. • Unlike other member variables, only one copy of the static variable exists in the memory for all the objects of that class. Ver. 1.0 Session 5 Slide 3 of 35
    4. 4. Object-Oriented Programming Using C#Static Functions Static functions can access only static variables. Static functions exist even before the object is created. Ver. 1.0 Session 5 Slide 4 of 35
    5. 5. Object-Oriented Programming Using C#Demo: Counting the Number of Times Function is Called by Using Static Functions Problem Statement: John a software developer in Zed Axsis Technology needs to check how many times a function is called. For the same, he has been asked to create the function called “CountFunction”. Help John to create this function. Ver. 1.0 Session 5 Slide 5 of 35
    6. 6. Object-Oriented Programming Using C#Introducing the .NET Framework The .NET Framework, introduced by Microsoft, aims at integrating various programming languages and services.

    8. 8. Object-Oriented Programming Using C#Introducing the .NET Framework (Contd.) .NET Products: .NET products aim at allowing developers to create applications, which are capable of interacting seamlessly with each other. All .NET products use eXtensible Markup Language (XML) for describing and exchanging data between applications. An example of a .NET product is Visual Studio .NET. Ver. 1.0 Session 5 Slide 8 of 35
    9. 9. Object-Oriented Programming Using C#Introducing the .NET Framework (Contd.) .NET Services: .NET helps you to create software as Web services. A Web Service is an application or business logic that is accessible through standard Internet protocols such as Hypertext Transfer Protocol (HTTP) and Simple Object Access Protocol (SOAP). You can identify the service by a Uniform Resource Locator (URL). Microsoft has come up with its own set of Web services, known as My Services. This service allows users to access data by linking calendars, phonebooks, address books, and personal references to the passport authentication service. Ver. 1.0 Session 5 Slide 9 of 35
    10. 10. Object-Oriented Programming Using C#Introducing the .NET Framework (Contd.) • The .NET Framework: It is the foundation for designing, developing, and deploying applications. It is the core of the .NET infrastructure because it exists as a layer between the .NET applications and the underlying operating system. Let us understand the .NET Framework in detail. Ver. 1.0 Session 5 Slide 10 of 35
    11. 11. Object-Oriented Programming Using C#Components of the .NET Framework The various components of the .NET Framework are: Common Language Runtime The .NET Framework Class Library User and Program Interfaces Ver. 1.0 Session 5 Slide 11 of 35
    12. 12. Object-Oriented Programming Using C#Components of the .NET Framework (Contd.) The following figure displays the various components of the .NET Framework.

    13. 13. Object-Oriented Programming Using C#Components of the .NET Framework (Contd.) Common Language Runtime (CLR): – CLR is the environment where all programs in .NET are executed. – CLR provides services such as code compilation, memory allocation, and garbage collection. – CLR allows the execution of code across different platforms by translating code into Intermediate Language (IL). – IL is a low level language that the CLR understands. – IL is converted into machine language during execution by the JIT compiler. During JIT compilation, code is also checked for type safety. – Type safety ensures that objects are always accessed in a compatible way. Ver. 1.0 Session 5 Slide 13 of 35
    14. 14. Object-Oriented Programming Using C#Components of the .NET Framework (Contd.) – CLR consists of a set of common rules followed by all the languages of the .NET Framework. This set of rules is known as Common Language Specification (CLS). – CLS enables an object or application to interact with the objects or applications of other languages. – The classes that follow the rules specified by CLS are termed as CLS-compliant classes. The classes defined in the .NET Framework class library are CLS-compliant. – One of the specifications defined in CLS is CTS, which provides a type system that is common across all languages. CTS define how data types are declared, used, and managed in the code at run time. – While executing the program, CLR: Identifies the process of compilation Identifies the process of code execution Ver. 1.0 Session 5 Slide 14 of 35
    15. 15. Object-Oriented Programming Using C#Components of the .NET Framework (Contd.) The .NET Framework Class Library: The .NET Framework class library works with any .NET language, such as VB.NET, VC++ .NET, and VC#. The .NET Framework class library 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. The .NET Framework class library comprises of: Namespaces Assemblies Ver. 1.0 Session 5 Slide 15 of 35

    34. 34. Object-Oriented Programming Using C#Summary In this session, you learned that: The static variable retains its value even after the function to which it belongs has been executed. The static functions can access only static variables. Non-static variables cannot be accessed by using static functions. The .NET Framework is made up of many components, such as Common Language Specification (CLS), Common language Runtime (CLR), and Just-In-Time (JIT) compiler. CLS is a set of rules that are followed by all the languages of the .NET Framework. When a program is compiled using Visual Studio .NET the compiler translates the code into the Intermediate Language (IL) instead of machine language. Ver. 1.0 Session 5 Slide 34 of 35
    35. 35. Object-Oriented Programming Using C#Summary (Contd.) The Just-In-Time (JIT) compiler is used to translate code from IL into machine language. The Common Language Runtime (CLR) is the environment where all .NET applications are executed. The Visual Studio .NET Integrated Development Environment (IDE) provides you with a common interface for developing various kinds of applications for the .NET Framework. Visual Studio .NET provides two types of containers, projects and solutions to organize the constituents of an application. Ver. 1.0 Session 5 Slide 35 of 35
