Question No.2 (5 Marks)

Explain how a relational DBMS deals with the object oriented data and what is the drawback of RDBMS in handling such data?

Answer

RDBMS software are developed using object oriented technique which allows, creating, modifying and querying the relational database.

DRAWBACK: the main drawback is wastage of time in translating the codes as, when we try to store the object-oriented data into RDBMS we have to translate it into suitable form for RDBMS and to read and use that data this RDBMS data has to be translated back into object-oriented form.

__ occurs when a function calls itself.

? Recursion

?Call by value

? Call by reference
? Parsing

Recursion occurs when a function calls itself to solve a simpler version of the problem. With each recursive call, the problem is different from, and simpler than, the original problem.

What is the difference between ‘single-line text input field’ and ‘password input field’ ?

ANS:

A Password Field is good for sensitive information. The only item that is absolutely necessary is the Submit Button. It is a good idea to include a Reset Button for the convenience of the user.
A text field gathers information using a single line of text. This field is useful for short answers. The default text field is blank. If you want to specify default text, use the VALUE attribute.

In JavaScript, what is event handling? What are the two types of events?

ANS:

        Event handling means capturing an event and responding to that.

Events e.g. onMouseOver, OnClick, onLoad, Onunload, updating the clock etc. are captured by the Java script & according to the programs they are responded accordingly

How can we include images in a web page using HTML and Java script?

ANS:

Image in HTML

It is easier to insert images and pictures i.e. JPG, GIF & BMP files in the web page through HTM codes.
The tag is used which is used as under:-
text<br Height=(in pixels) width=(in pixels)

Images in JavaScript
Images in JavaScript may be used with the event handling i.e. OnLoad, OnUnload, OnError and OnAbort etc.
The properties i.e. used for Java script are as under:-

  1. Name
  2. Border
  3. Complete
  4. Height
  5. src
    for example:-
    xyz” src=”abc.jpg”>

Elaborate Rester Graphics with examples.

ANS:

Raster graphics are digital images created or captured (for example, by scanning in a photo) as a set of samples of a given space . A raster file is usually larger than a vector graphics image file. A raster file is usually difficult to modify without loss of information.

Examples of raster image file types are: BMP, TIFF, GIF, and JPEG files. CS101 – Introduction to Computing – Q.No. 34 ( M – 5 ) What is a Relational Database?

CS101 – Introduction to Computing – Q.No. 35 ( M – 5 ) How many ways are there to call a function in a program ? Explain with example ANS: there are two methods of function in a program
1st method is used within the html coding with immediate in the even handling
on the other sidefunction can also be defined in the heading portion of the html page.
it is a better choice to use function as it include many statments in it.
OnMouseOver=“if(document.sendEmail.sender.value.length<1)
Window.alert(‘empty field!’)”
while in the heading portion
it will be as
function checkForm() {
if ( document.sendEmail.sender.value.length < 1) {
window.alert( “Empty Field” );
}
