Analysis of Transaction Processing Systems

It is the processing in which a system respond to a user’s command

to carry out some operation to and fro. The request or command is

called TRANSACTION, and the system carrying it out is called

TRANSACTION PROCESSING SYSTEM e.g cash machines. Transaction

processing systems are the systems working at a low level of any

organizational structure being operated by data entry operators etc to

collect and store data which is needed to be transported then to

decisional level of organisations. But it is important to make sure

nothing goes wrong at this level of handling data before it is

transported to upper level to be manipulated and then making decisions

based on information provided.

“There is some support for the propositions that

(1) Transaction processing systems should be able to be managed within

each work group in an organisation, managed that is with respect to

work stations in use and functionality available on those

workstations.

(2) exhibit very little model behaviour.

(3) support a high degree of operator independence or asynchornity.”

REFERNCE:

http://www.csse.monash.edu.au/~cavram/papers/tp/tr94-02h.html

There are 9 types of transaction processing models

1: Batch systems:

2: Monitor systems :

3: Time sharing systems

4: Advanced virtual terminal front end systems

5: Client server systems

6: Electronic mail and forms

7: Database based groupware

8: (IVR) systems

9: (EDI) systems

“Transaction processing systems are information systems which collect data and

distribute operational data both within and between organisations. The wide

spread use of networks and personal computers (used as terminals) has provided

feasible new options for the design of transaction processing systems”

b. DECISION SUPPORT SYSTEMS:

“Decision Support Systems (DSS) are a class of computerized information

systems that support decision-making activities. DSS are interactive

computer-based systems and subsystems intended to help decision

makers use communications technologies, data, documents, knowledge

and/or models to successfully complete decision process tasks”

Reference: http://dssresources.com/

Decision support systems are the computer information application

which collects and analyze data and then present it to the decision making

people of organisation i.e managers . decision support system as the name

suggest help and support managers to make effective ,right and timely decisions.

These systems store and process data at a much higher and efficient speed and

then represent the information in multiple forms which could be regular text ,

graphical representation, numerical etc which really enable managers to come

up with timely and right decisions.

As the decision makers could be different so can be the systems as

some work individually while other work in teams there are differences in

decision contexts, types, and makers.

“There are certain common traits that decision-making processes tend

to exhibit. They typically involve the phases of intelligence, design, and

    One look at an email can rob someone of 15 minutes of focus and one text message can result in someone blowing off something important, like school. Cell phones should not be allowed at Lindbergh High School. Many people disagree on whether or not cell phones should be allowed, but Monique Conrod speaks out the consequences of phones in an article called Schools Divided Over Cellphones in Classrooms. Ms. Conrod announces, “One of the main reasons, for banning cell phones is that they can distract students from their work… the students admitted they... used their [electronics] for things other than school for more than half the time they were in class” (Conrod).

  • Artificial Intelligence and its Effects on Business

    1711 Words  | 4 Pages

    In order to see how artificial intelligence plays a role on today’s society, I believe it is important to dispel any misconceptions about what artificial intelligence is. Artificial intelligence has been defined many different ways, but the commonality between all of them is that artificial intelligence theory and development of computer systems that are able to perform tasks that would normally require a human intelligence such as decision making, visual recognition, or speech recognition. However, human intelligence is a very ambiguous term. I believe there are three main attributes an artificial intelligence system has that makes it representative of human intelligence (Source 1). The first is problem solving, the ability to look ahead several steps in the decision making process and being able to choose the best solution (Source 1). The second is the representation of knowledge (Source 1). While knowledge is usually gained through experience or education, intelligent agents could very well possibly have a different form of knowledge. Access to the internet, the la...

  • Dfd Essay

    867 Words  | 2 Pages

    A data flow diagram (DFD) is a model which shows visual representation. The representation is comprised of information through systems, data and actors. These focus on how data is changed and being used during the process. DFD’s describes the system in many different process execution or collaboration of different process together as single process or bunch of data made into pieces are used in one or more process. The drawback of DFD is that no decisions are exposed and the processes are not sequential. To the simplest, a data flow diagram shows the flow of data in and out the system as specified in the requirement. It also gives the details of storage of information. DFD’s do not show the time taken by a process to change its state by the whole system. These are much useful for the visualization of data processing in the system, as to look what, where and to which data is being transferred. The data items may flow from internal data source to external data source or vice versa. DFD will not follow any algorithm, order of each and every execution on different circumstances.

  • The Negative Effects Of Cell Phones In The Classroom

    735 Words  | 2 Pages

    According to Porter (2013), “Technology has become a catalyst for distraction and off task behavior with students, tweeting, or prowling, through YouTube when they’re supposed to be listening to the teacher or doing classwork, promotes a lack of focus”. Cell Phones in the classroom would perform as a distraction to students learning. A small amount of students would actually be paying attention to their teacher and what he/she is instructing them and the other half of the students would not be paying attention. They would be surfing the web, playing games or be on social media, in which the classroom is not a room for participating in such activities Sooner than later cell phones being in the classroom would only cause a distraction and students grades would significantly display it.

  • Allowed In School

    834 Words  | 2 Pages

    As Olga Kharif from nbcnews.com has made clear that “ Many schools have banned cell phones in school, but educators have begun changing their rule of using cell phones in school and are using them for research and other useful things. Olga Kharif point is that some classrooms have found a way for cell phones to be useful in some class for research and brainstorming any kind of ideas for any project or class work, the same as any type of laptop or computer does. Josh Higgins from Usatoday.com agrees when stating that cell phones are useful in school by providing students with help and also teachers and staff are using phonesto keep track of students work and other things. The essence of Josh Higgins viewpoint is that cell phones are useful in many ways and that it could educate other students that cell phones can also be used for classwork and collaborating.Of course, it is possible to disagree with the view that cell phones are going to be useful and could help students learn and instead argue that using cell phones is a waste of time and won’t help students learn. Also, people would say that cell phones that are used in school are going to have a negative impact on students education because of how easy cell phones can help them find the answer on any type of work or even a take home test. However, the weight of the evidence is on the other side. What must be remembered is that cell phones are used as a tool.They could help with many kids who are having a hard time with something in school and can help collaborate with other students with research,classwork or a group project and it could help them a lot.But also remember that in some schools, some of the wifi that teachers and principles used can be tracked and that could lead to a student being caught on an inappropriate website or talking to another student in a different
