User Interface: Complexity, Types and Performance

User Interface: Complexity, Types and Performance User interface complexity A user interface is the means in which a person controls a software application. A user interface should provide the user with an easy experience, allowing them to interact with the software in a stress-free and natural way. The GUI (graphical user interface) is a program that contains graphical controls which the user can select with a keyboard or mouse. â€Å"The GUI complexity is the most important value to consider when selecting a technology for user interface classes. (Rayhan, 2003)†. To decide on the complexity of the user interface it is important to consider all possible user interfaces for the ePS system. We should also reflect on a variety of categories which include simple data input, static view of the data, customisable views, dynamic view of the data and interactive graphs. The simple data input allows the user to enter data into the system. The static view of data can be either a table, tree or graph that is not affected by the changes in the system data. â€Å"The customisable view allows the user to customise the appearance of static data without making a new request to the server. The dynamic view of data is automatically refreshed to stay current while the underlying system data changes. The interactive graphs are similar to dynamic views. The graphical view is automatically updated as the underlying system data changes (Rayhan, 2003).† Below is a list of user interfaces for the ePS system: Login user interface: The login user interface allows the user to enter their username and password to gain access to the system. Create E-Prescription user interface: The Create E-Prescription user interface allows the general practitioner user to create an E-Prescription for a patient, view their personal details and view their medical history. Dispense medicine user interface: The dispense medicine user interface allows the pharmacist user to view the patients E-Prescription, check if the medication is in stock and dispense the medicine. Manage ADR report user interface: The manage ADR report user interface will load a ADR report form on a web page for the user to enter in their adverse drug reaction to a particular medicine. Deployment constraints for user interfaces The deployment constraints are as imperative as the complexity of the user interface. When considering deployment constraints it is essential to have categories in which to compare. The following deployment constraints can occur within our ePS system: Any web browser on the internet: This deployment constraint must allow the user interface to perform on any web browser on any computer. The web browser Opera does not support Java which means that all images and much less dynamic HTML, so the user interface would be presented in text form only. Late-Model web browser on the internet: If each web browser is no more than a few generations old then we will also know that the computer is also no more than a few generations old. Number and types of users The number and type of users influence the technology selection in two ways. One influence being that a large number of users can force the technology for the entity, control and lifecycle classes to balance well. A large number of users can also encourage the selection of user interface technology. A larger audience makes straightforwardness of deployment and maintenance costs major factors. Small number of dedicated users: These are a small group of users who can help to outline the system and who profits from the system. Since these groups are willing to invest their own time to learn the system, functionality is the main priority. General use within an organisation: In regards to the system, this group of users are generally much larger, but they can be less motivated. These types of systems tend to support the organisation rather than contributing to the business. For example time tracking and benefits management. Large audience with high interest: The ePS system must have a large audience that are extremely involved. These users may be unconnected from one another. The users may log on to the system to exchange information e.g. the E-Prescriptions or to collaborate information about the patients and the medicine. Huge audience with low interest: In terms of the ePS system, it must attract and serve indecisive audience. If the ePS system runs slowly and wastes the audiences time it will cause the audience to be disengaged. Available bandwidth The bandwidth available is also another crucial factor when selecting technologies. Certain groups of technologies can allow developers to meet low bandwidth restrictions. However, other technologies make bandwidth constraints worse. The categories for bandwidth restrictions are as follows: Dial-Up connection: The dial-up connection is now the least common type of connection to the internet. However, Dial-Up connection is suitable for systems that let users view text, images and to enter data. This would be suitable for the ePS system when the user logs in and loads the ADR report form. The ADR report will load up on a web page. Fast internet connection: Fast internet connections consist of digital transmissions over phone lines, cables and satellite transmissions. This is mainly to enable a quicker internet connection. Dedicated network between client and server: This type of connection will allow the client and serves to exchange data at considerably high speeds. Types of System interface The technology for a system interface is determined by a current outer system. If an external system is not available, you must describe the system interface and then select an applicable private technology. System interfaces are divided into the following three categories: Data transfer: Many system interfaces exist merely to transfer large lumps of information from system to system. These interfaces are referred to as electronic data interchange. Services through a protocol: This system interface will allow a system to make requests through an agreed protocol. The server will allow a system to validate itself and request data by sending predefined codes. Direct access to system services: This system interface will allow a client system to directly call selected methods in the server. The server exposes these certain methods for remote access. Performance and Scalability The performance and scalability requirements are becoming one of the most important features in the selection of technology. Performance must be balanced against data integrity and any multiuser system and there aren’t many single user systems left. The performance and scalability factors are usually found by inspecting the class diagrams and sequence diagrams from the analysis model. The following are the three main categories that may affect the performance and scalability: Read-only: Certain systems only allow the user to view system data, but do not allow them to update it. Isolated updates: In most systems the user is allowed to change the systems data and the changes do no conflict with one and other. Concurrent updates: In some systems many users change the systems data, but with some changes affecting the same data. The following sections below describe the performance and scalability factors for each use case in the ePS system: Create E-Prescription use case: In the Create E-Prescription use case the system retrieves and displays the patient’s record. After the user enters the diagnosis and the system must update the current data with the new data. This use case is described as â€Å"Isolated updates† or â€Å"Concurrent updates†. Dispense medicine use case: In the dispense medicine use case the system retrieves and displays the patients E-Prescription. After the user checks the stock levels and dispenses the medicine the system must update the status to â€Å"Complete†. This use case is either described as â€Å"Isolated updates† or â€Å"Concurrent updates†. Record ADR use case: In the record ADR use case the system retrieves and displays the ADR entity objects. After the user updates the entities the system must update the data with the new data. This use case is either described as â€Å"Isolated updates† or â€Å"Concurrent updates†. Login use case: In the login use case the system locates the user entity object that corresponds to the actual user. Once the object is located, the system must determine whether the username and password is valid. The means the systems needs to read the username and password from some sort of persistent store. No data will be updated therefore the â€Å"Read-only† description is appropriate. Macro and Micro Environmental Analysis: Proton Macro and Micro Environmental Analysis: Proton Macro: Macro environment refers to the overwhelming and external factors that the firms cannot have the influence on which can affect its business if not addressed. The economy of Malaysia has been in a healthy growth, however it the year of 2012 has dropped. In addition, the inflation rates of the year 2012 have dropped from a whopping 2.7 to satisfactory 1.3 during a year. These factors have directly affected the inflation and unemployment rates of Malaysia, this is because the inflation rates have fallen and the unemployment rated have fallen as well. Micro: Micro environment refers to the internal factors that relates to a business environment which can affect the business’ operation. These factors are suppliers, shareholders, competitors, customers and distributors. These factors have played a very big rule in the performance of proton, where proton has a big problem with their suppliers, as well as a drop in its market shares, as they have a big competitor in the market which is Perodua, the other factor that has affected proton is the customs, where Proton is facing difficulties in dealing with their customers, in fact proton is losing its customers due to the lack of service and lack of trust. Cross Culture and Global Issues: Being an automobile industry, this firm has to deal with other cultures on a daily basis. Cultures are hard to define values, norm, and traditions. Understanding culture is an extremely complex concept. Various theories have been made on culture but the most projecting perhaps is of Greet Hofstede’s. Hosfsted’s Cultural Dimensions: Collectivism and Individualism: This refers to the extent to which people of a country a willing to work together. In collectivistic societies people tend to better put the groups needs first eliminating personal goals, whereas countries with invidualistic culture have follow personal or individual attainment over the groups. Power Distance: this refers to the extent to which people accept the hierarchal position to be authority in the business environment. Meaning in high power distance societies like Pakistan, India, Bangladesh, people tend to respect the authority because of their hierarchal of social status other than personal achievement like that in the low power distance societies like France, Italy. Uncertainty Avoidance: Refers to the extent to which people accept change in the society. Countries like Indonesia, North Korea, and Japan represent a high uncertainty avoidance whereby they dislike change. Masculinity and Feminism: relates to the role of women in different cultures, masculine culture believes Male to be the dominant part of the family and the only one allowed to support the family financially. Cultures with low masculinity dimension show females to be an important part of the workforce. Global issues: When it comes to addressing global issues to and automobile industry (Proton) most of the issues are relevant, whether it is of rising cost, taxation, global financial crises, regulations safety and health issues, all of the issues can be tracked back to an automobile industry (proton). There are many factors that Proton has to constrains before going overseas, for example, the tax fees is different in different countries, as well as the economic condition which will affect the sales, these are some of the issues that have to be addressed from Proton. Business volatility and risk Management: Considering the automobile industry (Proton), it took thousands of failed attempts before finally making a plane that could’ve worked. With every attempt being shot down, the amount of risk involved kept increasing but it was a necessary evil to reach to the point now where cars are made with perfection and counter abilities to have a safe driving. In the case of Proton, there are a number of risks involved which the mangers in charge have to think about. Initially, since the automobile industry is a huge business, the risk of investing enormous capital is the prime risk which decides the fate of the operation. Secondly, there is the risk of economic decline or inflation to sweep over which would directly affect the businesses in the service industry such as carmakers. Thirdly comes the cost of the fluctuating cost of material steals globally which has been increasing. The point is not to note out the risks involved the point is to manage risks relating to the merger effectively. Branding Success and Challenges: Branding is a concept originated for as far back as the 1200 in Sweden, where they used to burn insignia’s on a horse to differentiate it from others. For a company that wants its name out in the market, it takes extensive marketing, heavy funds, and a lot of patience because it takes a while. Reaching brand awareness is only the first step, and then the company needs to reach its target market, once it’s done then it comes Brand loyalty, whereby customers prefer choosing a brand they have become loyal to. If the brands present a particular negative perception of the company then it may take a long time and efforts to change the perception of the masses. For example, when Lexus was first revealed and appreciated by the masses, it was unknown that it belonged to Toyota, because of Toyota’s perception of being an economical and affordable automotive vehicle. Business Sustainability: It is one thing to start a business but it is another to sustain it. By sustaining it doesn’t always mean running it profitably, it also include social and environmental obligations, risk and opportunities it has. There are a number of ways in which companies can ensure their business sustainability which would be as follows; Shareholder engagement. Environmental management system. Reporting and disclosure. If proton implements these sustainable strategies into their operation and monito the quality, sustainability can be expected. Tuckman theories on teamwork: Introduction For the subject of Business and Commercial Awareness, we got an assignment to make a business plan for Proton. According to Dr Mahathir’s statement â€Å"our immediate plan would be to change its strategy from being a maker of cheap cars to become a world standard car manufacture†. Stage one: Forming The class was divided into a group of five members, each of the members was giving a department to work on, and these departments are Finance, Operation, Human Resource, and marketing. Unfortunately I was given Finance department, where I have to analyse the current situation of Proton’s finance performance. However, before the assignment my knowledge of finance was substantially lower than an average final year student of Business Administration, but I have had a mind-set to not pay attention to things that do not interest me for as far back as I can remember. Stage two: Storming Then we moved into the second stage which is storming, in this stage we started to push against boundaries. We have many conflicts between us in the nature of our working style, where each of the members has a different working style, for example in marketing department, where Amir and Khider were handed this part, they had many issues in solving the problems which cause frustration to the entire group, as well as I was giving Finance department, which was a big challenge for my authority. As the team work wasn’t clearly defined, which cause us to feel overwhelmed by the workload. I believe that it was mission impossible for us to overcome the issues we were facing in this stage; we could not even come up with the framework for our strategies, which was a big disappointment. We end up working these issues out with Dr Tan, and finally we could move to the next step. Stage three: Norming In this stage we finally identified our goals, and each of the members is fully aware of the methods and the strategies which should be adopted in order to achieve our goal. As well as trust and apperception was built between us, where the leader of our group Ben was a big motivation for us, he has helped each of us to take responsibility for progress towards achieving the goal. As most of the discussions were conducted through a facebook page. Stage four: Performing In this stage we solved all the problems and issues by using appropriate controls, and we have achieved and effective and satisfying result. It was amazing that we worked collaboratively to achieve our goal, as there was caring from the members towards each there. For example Brain Scot was very helpful in helping me with my part in Finance department, he recommended me on how to finalize my part. In addition to, the commitment from the group members increased positively towards the group work comparing to the first stage.

Short Essay About Dorian Gray :: Essays Papers

Short Essay About Dorian Gray In the early chapters of The Picture of Dorian Gray, by Oscar Wilde, we are introduced to a young and naà ¯ve character, Dorian Gray. Wilde’s descriptions of the young man create a picture of an innocent yet easily influenced Dorian, who is just beginning to learn what the adult world is all about. He is happy and handsome, yet when he is introduced to Lord Henry, he begins to experiment a little bit more on the side of sin. He becomes obsessed with youth and beauty, and he says that he â€Å"would give everything, even [his] very soul† to remain attractive and young. After this declaration, the reader is introduced to a changed Dorian Gray and his new philosophies about life, which begin to sound a lot like Lord Henry’s thoughts. Dorian â€Å"falls in love,† and then he breaks a girl’s heart, causing her to end her life. His beautiful portrait begins to alter, and to keep others from witnessing this, he locks the picture away. At this point in the novel, the reader is brought forward in time, and Dorian is now closer to middle age. Oscar Wilde uses very dark words to set a dreary mood and also a very different sort of image than from the beginning of he novel. Dorian’s life over the past years is described in detail, marking his drastic change and the hold the Devil has over him. It appears that Dorian’s conscience and his very soul have left his body forever, leaving him a sinful and very conceited person. People despise him, and some even leave a room when he enters. It is very clear that Dorian Gray has morphed into someone who is his opposite from earlier in his life.

This paper will discuss the local business of Fascinations Beauty Salon, and the internet strategic model to help develop this company. This business will have to have a new strategy that set up for the viable benefits. Fascinations Beauty Salon will need to be equipped in order to benefit from creating a website. This paper will also discuss the functions of the business through the internet website. Management Information Systems Fascinations Beauty Salon has been in business for quite a long time, like fifty years. It is located in the residential area down the street from an Elementary school and a Baptist Church. The owner Mrs. B. has been doing hair for the majority of her life in the same place and she still has plenty of clients. These clients have been her business for quite some time, and she shares her salon with another beautician that only works certain days. Just recently, Mrs. B. had been trying to research into expanding her business services and was asking about having her business on the internet. Mrs. B. had just realized that she wanted to be in the race with her competitors in the Galveston County area. I spoke to Mrs. B. he other day informing her that Fascinations Beauty Salon could expand the products that she sells on a regularly basis and as well as her services. Between the women that work at this place and the students that have been in the business to get a feel, or trained with internships that she should have a website. So that when people want or need some sort of hairstyle or needs a clip or maybe even a product that only she carries that, they could send a quick electronic email out to the business or they could go to her place of business to receive such services and products. I explained to her that E-commerce is a way that patrons and businesses are getting fast admission to the internet global market. E-commerce is spreading like a wildfire, in the areas of exporting and advertising of manufactured goods and benefits by the usage of central processing units and systems. I advised her that she could triple her business and that I would set up her business with an electronic commerce with a certain type of internet industry example like (B2C) industry-to-customer: which means that ustomers can buy immediately with her company instead of trading with any liaisons. Mrs. B. inquired about the ways that a web site could assist her in benefitting, and I informed her that a web site could assist her company receive a viable gain with a planned effect on her business.

Social And Social Learning Theory - 1553 Words

The Social Learning Theory is best defined as crime is learned through associations with others who commit crimes. Juveniles are very impressionable or gullible, wherein they want to be popular or part of the in-crowd or clique. In comparison to the 1970’s versus today, juveniles are emulating criminals depicted on television not just through associations. Consider the current state of technology, specifically the internet and websites such as â€Å"You Tube.† With respect to crime and juvenile delinquents, You Tube is and can be a negative influence. In addressing the topics of associations and crime, the Columbine massacre, as well as the current school shootings, can be attributed to the Social Learning Theory. Social Disorganization Theory The Social Disorganization Theory was discovered by researchers Shaw and McKay. This theory focuses on the family, neighborhood, and economic environments of youths. Social Disorganization and Social Learning have similarities with respects to association. The Social Learning Theory emphasizes crime occurs because of association with other criminal elements. Conversely, the Disorganization Theory accentuates crime is attributed to where an individual resides. If both theories are coalesced, the residential location coincides with association. Normally, juvenile delinquents tend to associate with other individuals from their neighborhoods, as well as schools.
