Extractors is a data retrieval mechanisms in the SAP source system. Which can fill the extract structure of a data source with the data from the SAP source system datasets. The extractor may be able to supply data to more fields than exist in the extract structure.

With HTML5, it is possible for the web pages to store the data locally in the user's browser. This web storage is much faster and secured than the cookies. Also, a larger amount of data can be stored without causing any adverse effect to the performance of the website. 

The data here is not included with every server request. It is used ONLY when it is asked for. It is only that particular web page that can access the data stored by itself.

The main reason why the scope resolution operator (::) cannot be overloaded is that only operators that take in values as parameters can be overloaded. The scope resolution operator does not take a value as parameter.

JavaScripts uses a hierarchical structure that applies to the objects in a document. There are some objects that show the relationship of one object to another using the language.

Window object: This is the topmost object in the hierarchy. It represent the content area of browser window that consists of HTML documents. Each frame is also a window that has some actions inside it.

Document object: This object gets loaded in a window and consists of objects of different kind in the model. It consists of the content that will be written in the script.

Form object: Form objects are used for more interaction with the users. It represents the form elements inside <FORM>...</FORM> tag.

- This can be done by defining the frame with SCROLLING = auto and having content to just fit into this frame. 

- SCROLLING="yes" gets the scroll bar on both the sides, even when not needed. 

- SCROLLING="no" doesn’t get the scrollbars at all, even when they are needed.

Creating partition may serve different purposes. The common reason is that a separate partition can be used to store data files so that when Windows needs to be reinstalled, the main partition can be formatted without fear of loosing data, which are stored on the other partition.

For web application we perform following time of test:

1. Functionality Testing.

2. Usability Testing.

3. Navigation Testing.

4. Configuration and Compatibility testing.

5. Reliability and Availability Testing.

6. Performance Testing.

7. Load and Stress Testing.

8. Security Testing

The web hosting on the server can be accomplished by using the IP based hosting that provides resources and services as follows:

- IP based hosting provides dedicated IPs that consists of virtual hosts and having the different IP address. 

- Web server is configured with different and multiple physical network interfaces using the same physical interface. 

- Web server uses this IP address to connect the client with the server to determine the web site that provides the client a view of it. 

- IP addresses provide the resources that are required in order to use the SSL certificates and other resources rather than shared certificate.
