Information system problems

Chapter #6 List and describe three main capabilities or tools of DBMS.

I would like to show three main capabilities of DBMS definitions. The system has a data definition capability to specify the structure of the content of the database. This capability would create database tables and define the characteristics of the fields in each table.

A data dictionary would store definitions of data elements, and their characteristics, in the database. The data dictionary may capture additional information, such as usage, ownership, authorization, security, and the individuals, business functions, programs, and reports that use each data element.

 A data manipulation language, such as SQL, is easy to add, change, delete, and retrieve the data in the database.

Chapter #7 what has made the Google search engine so successful? Discuss.

              The biggest reason for Google's success is that they provide the best search results for their users. Actually, their search engine is frequently used by various kinds of web sites.  The reason why many people believe the quality of function is they are constantly updating their search algorithm and ensure that when you search for something you will get the best and most relevant results.

Chapter #8 what is a digital certificate? How does it work? Explain.

This is a kind of security barrier. A digital certificate is an attachment to an electronic message used for security purposes. The most common use of a digital certificate is to verify that a user sending a message is who he or she claims to be, and to provide the receiver with the means to encode a reply.

People wishing to send an encrypted message applies for a digital certificate from a Certificate Authority (CA). The CA issues an encrypted digital certificate containing the applicant's public key and a variety of other identification information. The CA makes its own public key readily available through print publicity or perhaps on the Internet.

The recipient of an encrypted message uses the CA's public key to decode the digital certificate attached to the message, verifies it as issued by the CA and then obtains the sender's public key and identification information held within the certificate. With this information, the recipient can send an encrypted reply.

 

Chapter #9 Identify five benefits of customer relationship management systems.

              There are 5 benefits of customer relationship management systems such as improved customer experience, focused marketing efforts, automated analytics and reporting, better coordination and cooperation, more administrative support.

At first, I would like to show improved customer experience. I think this is really efficient method to make a relationship with customers without frustration. The concrete example is that a customer relationship management system will enable us to quickly identify customers, address their initial needs and recommend additional products or services that match their profile.  It gives staff the ability to recognize who they’re dealing with from the very beginning, making them more efficient and more productive. Customers could enjoy better customer service.

The second one is about focused marketing efforts. This is a way of finding a most reasonable and efficient methods. CRM solutions provide us with a complete picture of sales pipeline, as well as our existing customers. It means we can identify and target individuals with the greatest potential for future sales. Rather than taking the mass marketing approach, CRM allows us to focus and fine-tune your marketing efforts to make those efforts more productive. That saves us money and efficient, because we aren’t expending resources on individuals who ultimately won’t become customers.

The third one is about automated analytics and reporting. Whether your business is large or small, chances are you don’t have time to track and analyze the buying habits of every last customer.  The beauty of customer relationship management applications is that they handle that piece of the marketing puzzle for you. Because your customer and sales information is housed in one place, you have automatic access to a full range of reports on which products or services are selling and who’s buying them.

The fourth one is better coordination and cooperation. When sales, marketing and customer service share a common CRM platform, they are able to speak the same language with one another. Rather than being separated by systems functionality or access to key information, departments across the organization are able to function more cohesively. Suddenly, they have what they need to work as a single unit. They know what the goals are and how to attain them.   The last one is more administrative support. Even in sales, there are mundane tasks that simply have to get done. Scheduling appointments, keeping records up-to-date, tracking follow-ups—all critical functions in any sales team, but ones that require careful (and tedious) attention to detail.

 

Chapter #10 what methods could a portal use to generate revenue? Which do you think might be most successful, and why?

              For example, there are so many reason that portal devise succeeded. Smart phone is a lot of function such as maps, games, calendars and so on. Business person and student use the devise by various types of usages. It’s a communication devise and also entertainment devise. The camera’s function is really high level technology. Its quality is almost the same as real cameras. Nowadays, social media networks are growing and expand. The compatibility of the devise and the network is remarkable. Many people take a picture by the device and upload and post on Facebook.  The success is not only the devise functions.
