I have to create a 5-7 -slide Microsoft PowerPoint presentation to teach your fellow students about the follwing IT applications: Transaction processing systems. knowledge management systems, Expert system and artificial intelligence, Enterprise resource planning systems, E-commerce systems. I have to include detailed speaker notes and examples.
Hello,So how would you like to proceed? Do you need just the content of the slides or the entire Power Point? Also, what version of Power Point do you have?
Hi syseng - sorry to i did not get this until this morning. Yes. if you could provide an example of an entire powerpoint that would be great. if not that's okay also. I have microsoft office powerpoint 2007.
Relist: I still need help.
Hello - I apologize for the delay. I do not have Power Point 2007 but do have 2003 and would need more time to complete an entire power point presentationg.
Hi Syseng - How much do you need it's due by tonight? I could probably complete a power point myself. It's just layout of info that I really need?
Is this the kind of information you need?Transaction Processing Systems:
A collection of operations on the physical and abstract application state that includes the following properties:
Atomicity – All or nothing commit, jump from one state to the next without an observable intermediate state.
Consistency – The transaction is a correct transformation of state (is as expected).
Isolation – Though transactions can execute concurrently, they appear to the observer as if they were executed in serial (each transaction separate).
Durability – When a transaction is committed, it’s changes remain even when the system fails.
The acronym is ACID.
From a user perspective:
• Any coherent sequence of operations that satisfies a goal;
• For example - find the times of flights from London to Paris.
If the above format is something you could use to add to a power point then I will work to include the rest in this forum.
yes. this wil be great. When can you have it done?
Let me know if the below information is what you need:
Knowledge management systems:
A knowledge management system allows for global access of and organization’s collective knowledge to provide faster learning, sharing of information, and collaboration within the organization.
Knowledge is a fluid mix of framed experience,
values, contextual information, and expert insight
that provides a framework for evaluating and
incorporating new experiences and information. It
originates and is applied in the minds of those that know. In
organizations, it often becomes embedded not only
in documents or repositories but also in
organizational routines, processes, practices and
Three aspects of knowledge management include:
Technology – The system employed to manage knowledge assets.
Process – The procedures necessary to ensure knowledge is both captured and accessible.
People – The actors that are guided by the process, utilize the technology and generate the knowledge.
Expert systems and artificial intelligence:
Artificial Intelligence is concerned with programming computers to perform tasks that are presently better done by humans. (Minsky)
Humans “Understand” information but tend to overlook edge cases when looking for solutions.
Computers look at the details but do not “Understand” problems.
• Representation and manipulation of Domain Knowledge
• Perceive analogies
Expert Systems are a subfield of Artificial Intelligence. They focus on mimicing the thought process of a human “Expert” through:
• Separation of facts, knowledge, and inference knowledge is explicit, not hidden in algorithm
• Simulates Human reasoning Built from approach of Human Expert
• Uses approximate or heuristic search
An Expert system is built from:
• Human Expert - Can solve problems; and we desire to solve the problems without the expert.
• Knowledge Engineer - Can communicate with HE to obtain and model the knowledge that we need in the system
• Programmer - Builds and maintains all the necessary computer programs to bring the model to life.
• User Specifies what problems we need to solve (needs the expert)
Enterprise resource planning systems:
ERP attempts to integrate all departments and functions in an organization across a company onto a single system (computer system) that can serve all departments and their particular needs.
ERP automates the tasks involved in performing business processes.
Business processes such as sales order processing and manufacturing procurement are examples of business processes that are supported by ERP.
A properly installed and configured ERP system has a fantastic ROI!
First a definition of Ecommerce:
“Electronic transmission of buyer/seller transactions & related info between individuals and/or businesses”. Think of it as buying/selling over the Web and including the entire online transaction process.
Ecommerce systems make electronic buying and selling possible, covering three areas:
Business to Business transactions – B2B
Business to Customer transactions – B2C
Customer to Customer transactions – C2C
The transaction cycle includes:
Attract – The look and feel of the site that brings customers/users
Inform – The system/site provides relevant information to the user
Customize – Provide the user with the ability to customize their environment
Transact – Meets the requirements of buying and selling models
Pay – Secure electronic payment support
Interact – Provides customer service portal and social interaction avenues
Deliver – Order fulfillment support
Personalize – Tracks buying behavior and encourages more
