The database laboratory exercises are open labs meaning that they are unscheduled but are expected to require 80-90 hours of activity. The programming oriented labs should be done in pairs. More ambitious projects will require a team effort which will provide an opportunity for a variety of roles - excellent resume material.

Several projects are available to cater to the goals and/or major of the student. Students are expected to commit to a project and a specific RDBMS early in the quarter. Neither the textbook nor the lectures may cover enough material to complete the project. You are expected to determine what additional materials are needed and obtain them in sufficient time to complete the project. You may

need to obtain

1. DBMS specific guides,

2. GUI interface programming guides, and

3. other materials.

Students who would like to work on a different problem may propose an alternative project at any point in the quarter. The project must be well-defined, approved by the instructor, and involve roughly the same amount of work as the remaining assignments.

Types - External Style Sheet

This will be very useful when we have so many styles defined. We will want to take all the styles in to a different file. That's what we do in External CSS. We take all the styles in a external file and map it with the html page. 

Example:
We will put the following style in a text file say mystyle.css
<style>
.mystyle1
{
color: green;
background-color: orange;
}
</style>


In our head we will link to the external style sheet using the tag link in header portion
Tag:
<head>
<link rel="stylesheet" type="text/css" href="mystyle.css"/>
</head>
The names used for user defined styles should not belong to any html tag. We set the style for the tag using the attribute "class".
Example1:

<font class=mystyle1> MY STYLE </font>

Result1: 

MY STYLE 

Example2:
<a href="index.php" class=mystyle1> MY STYLE </a>

Result2: 

MY STYLE 

Types - User Defined

Here user defines his own style and uses it anywhere he wants.

Code:
<head>
<style>
.mystyle1
{
color: green;
background-color: orange;
}
</style>
</head>

The names used for user defined styles should not belong to any html tag. We set the style for the tag using the attribute "class".

Example1:

<font class=mystyle1> MY STYLE </font>

Result: 

MY STYLE 

Example2:

<a href="index.php" class=mystyle1> MY STYLE </a>

Result: 

MY STYLE 

Internal Styles - Identifiers

If we use internal styles with identifiers, we have to set the id for the style to take effect. 

Code:

<head>
<style>
a#test1
{
color: red;
background-color: orange;
}

a#test2
{
color: green;
background-color: yellow;
}
</style>
</head>


<a href="index.html" id=test1> Index </a><br><br>
<a href="index.html" id=test2> Index </a>

Now you can see how we have different styles for the same "a" tag. 

Note 1: If required you can using <span> instead of <div> tags. div tag will start and end on new lines. span will not exceed the tag area.
