Explain HTML Helper with its types and examples also.

-

  •  An HTML helper is just a method that returns an HTML string.
  • The string can represent any type of content that you want.
  • For example: We can use an HTML helper to render standard HTML tags like <input>, <button>, <img> tags etc We can also create our own HTML helper to render more complex content.


 Types of HTML Helpers:

a. Inline HTML helper: Created in same orang view by using the Razor @ helper tag.

 Eg: <h3> Programming languages: </h3> 

 @Listing Items (new sting [ { "C","#" C++})


b. Builtin HTML: These helpers are extension methods on the Html Helper class.

 Eg: TextBox : @ Html: TextBox ("Textbox1", "val")

 output :- <input id ="Textbox 1" . name = ""Textbox1" type="text" value="val"/>


c) Custom HTML helpers: We can create our own custom helper method by creating an extension method on the Html helper class.

 Eg: public static class Custom Helper

public static MVC Htmlstring Submit Button (this HTMLHelper helper, string button Text)

{

string str = " <input type = \"submit\" value=" "+ button Text + "\" />"} 

 return new MVCHtml Spring (str);

}

}

}

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

What is national data warehouse? What is census data?

National Data warehouse   A large number of national data warehouses can be identified from the existing data resources within the central government ministries. These are potential subject areas in which data warehouses may be developed at present and in the future. Census Data Census data can help planners and others understand their communities' social, economic, and demographic conditions. Census data is the primary data used by planners to understand the social, economic, and demographic conditions locally and nationally. We sometimes think the census is unique to the United States, but census data is collected in other countries.  The total process of collecting, compiling, and publishing demographic, economic, and social data about a specific time to all people in a country or fixed or defined area part of a country. Most countries also include a housing census. A census is a procedure of systematically acquiring and recording information about the members of a given populat
