Explain PARTIAL CLASS.

 PARTIAL CLASS

  •  It is possible to split the definition of a class, a struct, an interface or a method over two or mon source files. Each source file contains a section of the type or method definition, and all parts a combined when the application is compiled.
  • When working on large projects, spreading a class over separate files enables multiple programmers to work on it at the same time. When working with an automatically generated source, code can be added to the class without having to recreate the source file. Visual Studi uses this approach when it creates Windows Forms, Web service wrapper code, and so on.
  • To split a class definition, use the partial keyword modifier, as shown here: 

public partial class Coords

{

private int x;

private int y;

public Coords (int x, int y)

{

this.x = x;

this.y = y;

}

public partial class Coords

{

public void Print Coords()

{

Console.WriteLine("Coords: (0), (1)", x, y);

}

class TestCoords

{

static void Main() 

{

Coords myCoords new Coords(10, 15); 

myCoords. Print Coords();

// Keep the console window open in debug mode. Console.WriteLine("Press any key to exit.");

Console.ReadKey();

}

} //Output: Coords: 10,15

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...

Suppose that a data warehouse consists of the three dimensions time, doctor, and patient, and the two measures count and charge, where a charge is the fee that a doctor charges a patient for a visit. a) Draw a schema diagram for the above data warehouse using one of the schemas. [star, snowflake, fact constellation] b) Starting with the base cuboid [day, doctor, patient], what specific OLAP operations should be performed in order to list the total fee collected by each doctor in 2004? c) To obtain the same list, write an SQL query assuming the data are stored in a relational database with the schema fee (day, month, year, doctor, hospital, patient, count, charge)

Solution: a) Star Schema is shown in the figure below: b) First, we should use the roll-up operation to get the year 2004(rolling-up from the day then month to a year). After getting that, we need to use the slice operation to select (2004). Second, we should use roll-up operation again to get all patients. Then, we need to use the slice operation to select (all). Finally, we get a list of the total fee collected by each doctor in 2004. So, 1. roll up from day to month to year 2. slice for year = “2004” 3. roll up on patient from the individual patient to all 4. slice for patient = “all” 5. get the list of the total fees collected by each doctor in 2004 c) Select doctor, Sum(charge) From fee Where year = 2004 Group by doctor

What is RMI? Discuss stub and skeleton. Explain its role in creating distributed applications.

-
 The RMI (Remote Method Invocation) is an API that provides a mechanism to create distributed application in java. The RMI allows an object to invoke methods on an object running in another JVM. The RMI provides remote communication between the applications using two objects stub and skeleton. RMI applications often comprise two separate programs, a server and a client. A typical server program creates some remote objects, makes references to these objects accessible, and waits for clients to invoke methods on these objects. A typical client program obtains a remote reference to one or more remote objects on a server and then invokes methods on them.  RMI provides the mechanism by which the server and the client communicate and pass information back and forth. A primary goal for the RMI designers was to allow programmers to develop distributed Java programs with the same syntax and semantics used for non-distributed programs. To do this, they had to carefully map how Java clas...
