SOAP
What is SOAP
SOAP stands for Simple Object Access Protocol. SOAP is a communications protocol that is designed to communicate using the internet. SOAP is a light weight Protocol. SOAP is based on XML and allows for communications to take place between applications using HTTP and XML language. SOAP can also be used with Simple Mail Transfer Protocol (SMTP) and Python. SOAP was originally developed by Microsoft, UserLand Software and DevelopMentor and has been proposed as a standard to Internet Engineering Task Force (IEFT). SOAP can also be used for broadcasting messages. In the diagram below we show how SOAP converts procedure calls to and from XML messages [1] [2]
Figure ?? Procedure calls to and from XML messages [A]
SOAP has four main areas
• Message Format - describes the way a message is to be packaged as an XML document. We will go into this in more detail in the next section.
• Description - what Protocol should be used to transport the SOAP message i.e. HTTP or SMTP.
• Set of Rules - A list of rules that are used to process a SOAP message and a list of the entities involved in the process.
• Set of Conventions - the turning of a Remote Procedural Call (RPC) into a SOAP message and back.

Soap Message Structure
SOAP XML document consists of the following
• SOAP Envelope (Mandatory)
• SOAP Header (Optional)
• SOAP Body (Mandatory)
• SOAP Fault (Optional)
The picture shown below is a pictorial representation of the SOAP message

SOAP Envelope
SOAP Envelope is the start and end element of the XML document. All the information of the SOAP Envelope is contained within the following tags [information]

• - mandatory element and provides the fault information in plain english. It contains one or many elements as child elements of the Fault element. These Text elements contain information about the fault in several languages.[5]
Example of Reason Element code that shows an error message in english and danish

Error in Input Data
Fejl i input data
• - contains the URI of the SOAP node that generated the fault and is optional[5]
• - notes the URI of the node that identifies the Fault and is optional.[5]
• - optional element and contains application specific information relating to the SOAP-fault-codes depicting the fault. [5]
“Lather And Nothing Else” by Hernando Tellez, shows suspense in many ways, by using key elements. The key element that Tellez uses, develops suspense in the story. Tellez uses many different elements to show suspense like using mood and tone to make us feel something. In "Lather And Nothing Else” Tellez used style, the point of view, and pace to build suspense into the story.
Skeleton: which is a server side stub. It is responsible for unmarshalling arguments, invokes methods, marshals results and sends the results to sending proxy
d) The first five bytes of the returned document are<!doc. The server agree the persistent connection as it contains keep-alive.
Command XML consists of commands that the database needs to carry out. It also contains user name and password for authentication purpose.
The program will monitor the user input and will notify immediately of a wrong action (like a key stroke the is not valid for the particular input), will create an error file that contains the data set that contains the error to be analyzed and investigated, or the entire batch of data will be rejected, if the errors cannot be attributed to an specific record, for the user to locate issues and resubmit a corrected set.

Antibacterial soap has been a product on the market that people have trusted for many years to knock out germs and keep them from getting sick. New data, research, and rules that are surfacing have the potential to change the product’s popularity. Antibacterial soap is ineffective and should be taken off of the market because the chemicals in it can be harmful, too much exposure can cause resistance to antibiotics, and it has not been proven to have more of an effect than regular soap and water.
The reasons for this - a missing hyphen. However there are many more reasons for software systems failure, and most of them are due to human negligence that leads to software failure. There are two types of software systems...
According to Sommerville (2011), the Provides interface are services provided by the component, where the Requires interface specifies what services are needed by the other components in the system to operate correctly, (p. 457). The hospital wants to improve the tracking of VOIP calls which are made within the hospital system. The emergency control room will have a system for the call-logging component which will record the calls made. The first component would be for tracking the phone calls. The Require interface can be the caller id service which feeds into the component. With the caller id service, the Provides interface will be to see the phone number calling to, the phone number calling from, the time of the call, the length of the call, and a log file to see all the calls place from a phone or all phones. To track the calls the management is going to wait to see the phones numbers of the internal calls are from and to. Management is going to also want to see the time of the call and how long the call lasted. If management believe employees are spending too much time on the phone talking and doing it more often than needed, management can pull a log of those tw...
One of the clinical skills which I become competent in during my clinical placement is bed washing a patient. I had little or no knowledge of how to wash a patient in a hospital before and this training has provided me an ample opportunity to learn this skill. The reflective model I have chosen to describe my essay is Gibbs model (Gibbs 1998).Gibbs model of reflection is one of the most popular models of reflection and divided into six step process of reflective cycles. These are incorporates in the following: Description of the event, feelings, evaluation, analysis, conclusion, and action plan. I would use this model to describe my essay while relating the theory to the practice.

Electronic Mail, a means of communication that is growing at a very rapid rate. In this paper, I will write about introduction of e-mail, the advantage and disadvantage of e-mail, mailing lists, sending an e-mail message, sending attachments, e-mail improvement, and security features. Introduction of Electronic Mail Electronic mail (E-mail) has become popular and easy way of communication in this decade. E-mail is a method of sending and receiving document or message from one person to another. E-mail is not only replacement for postal mail and telephones, and also it is a new medium. E-mail send plain text, images, audio, spreadsheets, computer programs can attach to an e-mail message. Using the e-mail, you must have a computer on a network. The computer must require a modem and phone line. Sending and receiving e-mail needs an e-mail program. Every e-mail user requires an e-mail address. This e-mail address is similar to a postal address. E-mail address is written as username@domain, for instance, PCLEE@juno.com. The username is used for sending and receiving e-mail.
