SaaS and Cloud Computing - Assignment Example

Intro to Management Systems Week 10 "SaaS and Cloud Computing" Question No Answer A: Using Software as a Service (SaaS) eliminates the cost of installation/purchase as well as cost of maintenance and upgrade. The SaaS applications are easier to download and maintain. It also saves time of customers because maintenance responsibilities are transferred to IT department and user just connects through the internet and acquires a log in. Robustness, privacy, security and reliability are main disadvantages of SaaS for an organization. Answer B: Rapid adoption and acceptance of the SaaS has been due to its wider applications used for communication, accounting and customer relationship management. Its advantages are obvious as compared to disadvantages. Low cost and time saving has made it a delivery model for various business applications. Question No. 2 Answer A. Data location is one of the security risk revealed by Gartner in textbook. Users might want to know the exact location where data is hosted. One does not know the place where cloud servers are placed, but believes that where cloud servers are located that is a safe place and no security risk is for stored information. Answer B. It is said that users have concern about data security and does not need to know where data is located. However, users of cloud computing service believe that local privacy requirements are met by authority keeping the cloud servers. "Course Conclusion" Question No 1 Answer A. Important elements to be covered so for include the hardware, software, data and communication, people and procedures. Answer B. All these elements combine together and help the businesses in transaction processing, decision support and business management. Question No 2 Answer A: n Figure: Linear hierarchy of Basic concepts of a MIS Answer B: In the above figure, important concepts relevant to a Management Information System are given in a linear hierarchal way. Response management system, health information system, and sales information system are the main classes of MIS. Its services are numerous for business organizations. UML Question No.1 Answer A: Both UML and pseudo code are vital for designing and development of an online course delivery system. A UML of the online course delivery system will give graphical view of the system. Use Cases or other diagrams of UML save time for developers because system requirements are elicited very early in software development life cycle. Answer B. Pseudo code is another way of system representation in non-graphical view. It allows the developers/software engineer to specify levels of design description, which are required for each situation. Initial approach of UML is more suitable than pseudo code because it helps the software engineers throughout the life cycle of a system. It provides basic guidelines to developers for system designing and development. Question No. 2 Answer A: A class diagram is mostly used by developers. This diagram is core for system designing and development. Objects and relationship among them are represented in a class diagram. Constraints and properties of classes are signified in the class diagram. Answer B: Classes are shown by boxes with three parts. Name of class, its attributes and operations are main parts of a class. Class diagram also shows the relationship between business objects, individual employees and outside parties in a sales business system. Objects Question No. 1 Answer A: Video, customer and account are the objects, which are associated with each other. A customer will have a single account to view the video. A customer can browse more than one video at a time. Answer B: A customer cannot have more than one account, so cardinality of this association can be represented as 0….1. In other case, a customer can view more than video and cardinality is given as 1…n. The association involves at least one video per customer, but possible more than one video. Question No. 2 Answer A: The Entity Relationship Diagram is used for modeling the classes or objects used for the system development. Other ways of showing the objects with their association is a complex matter. Answer B: Accurate maintenance of objects like video, customer and account requires the special attention of developers. Symbols used in ER-model clearly show the inheritance in a simple way with the graphical style. A developer can code the system after viewing the symbols in the ER-diagram. Course Takeaway Question No. 1 Answer A: Theoretical concepts about modeling of the MIS have been learned very well in a lesson about UML. Various modeling technique are clearly understood in this lesson about Management information system modeling. It is also known that how software engineers use the modeling diagrams and develop their system. Answer B: Throughout this lesson, all basic modeling diagrams were studied with the examples. However, class diagram of a scenario was asked to be developed after identification of main classes of a sales system. Association between classes was also established. Question No. 2 Answer A: This type of course is essential for every professional developer as it provides guidelines for MIS development from a low level to a large scale. Sometimes, computer programmers hold degree in a different field of science like mathematics, information systems and accounting but they require the management information system course for better performance in the organizations. Answer B: Information management in the business organization is a basic need for success of a business; only a graduate with such course can understand and perceive the upcoming technology for information management. Data Information Decision Question 1 Answer A: Database administrators are responsible to manage the database by employing security and backup recovery procedures, and performance evaluation. Answer B: Database administrator is also responsible for periodic training of staff using the system and decides what role and privileges be given to specific users. Question No.2 Answer A: Sensitive data must be backed up carefully which cannot be accessed by unauthorized users. Answer B: All users must be given username and password and activities performed on every account must be watched. Firewalls and paid antivirus applications must be installed on the systems. Database Trends Question No. 1 Answer A: US healthcare database management and Retailing sales companies are two different industries, which are using common data exchange and data management trends (Gray et al., 2014). Answer B: Electronic health record system in USA ranks above others due to its success factors of ease of use, implementation and cost. On the other hands, Sales companies like Apple, Dell and Adidas have their information management system, but require the strong control for use of their distributed systems and cost. Question No. 2 Answer A: Cyber Business is being promoted in China as well as USA through Google, and data exchange and data management is becoming hard to be managed. Data security on regular base has become a routine. Answer B: However, on changing scenarios, it is easier to speculate that a complete turn will occur and bio-identity will be used for each of activity done through present software. Reflection Question No.1 Answer A: It is learned from e-activity that a covering letter needs to be precise according to job details and must summarize the resume. It should be persuasive that a recruiter has many choices. It should be clearly drafted in a latest format. Detect any mistake in the covering letter and never forget to sign it. Answer B: It should be written like a formal letter and data must be at top-center or top right side margin in start right the name or designation of person whom it is being sent. Subject of application needs to be mentioned here. In the end write name of applicant, address. Clarity of language, appropriate qualification and experience if required are key factors, which are key factors. Question No. 2: Answer A: Listening to others is a communication skill that makes someone not only listen or communicate to others but also understand what speaker feels about his communication. Answer B: Managing stress is another communication skill and quick learning also reduces the stress. Feeling and emotions must be regulated for the effective communication. Course Wrap-Up Question No. 1 Answer A: This class is important for those who have no basic knowledge of information management for business growth. Answer B: This course classes are meaningful for those who have less knowledge about information management because information security is key concept that was revealed in classes. Question No. 2 Answer A: Professional competencies in the organizations are developed through the information management systems.
