Every architecture rely on a database that is easy to maintain and gets easily configured Amazon uses the database by the name SimpleDB. This is the database that is used for cloud architecture to track the statuses of the components. The component of the system are asynchronous and discrete, it requires capturing the state of the system so that in any failure the user can easily revert back to its normal configuration. SimpleDB is schema-less database and there is no need to define the structure before the creation of any data. Every controller in the database defines their own structure and link the data to a job.

- The web pages that are loading slowly might be using heavy scripts or might be getting loaded on an overloaded server. 

- If the content like flash is used then the web page performs really slowly in comparison to the normal pages that get created. 

- If the caching is inactive on the web browsers and the same web page is getting loaded again and again then the performance get degraded.

- Web pages load slowly due to the content on that page as if it is text it loads faster then the site that is made up of large photographs. 

- It takes longer time for a picture to get rendered and the transmission time also remains higher then the text.

Use case is nothing but the functional specification document in which all the customer requirements are documented.

Test case is a document which tells wat to test, steps to test and expected and actual results.

The application layer of an R/3 System is made up of the application servers and the message server. Application programs in an R/3 System are run on application servers. The application servers communicate with the presentation components, the database, and also with each other, using the message server. All the data are stored in a centralized server. This server is called database server.

bcoz interface does not contains any initializers and constructors to initialize its data members.
