What is the difference between an information system and a computer application?

When looking into the information system, which is a set of interrelated computer components that collects, processes, or stores the information needed to completed (Satzinger, 2015). When looking into computer application, which is a computer software program that executes on a computing device to carry out specific function or related functions (Satzinger, 2015). The major difference between these two items is that information system is mainly a software, with a database and other processes, which computer applications is only a computer software. This is mainly only a single computer program that it operates with. What is the purpose of systems analysis? …show more content…

This is use case description that models that textual model that list and describes the processing details for a use case (Satzinger, 2015). This is the most formal method to used by documenting the use case, which having a good description helps the user understand what is going on. Another detail would be preconditions or post conditions. There help with either the user inputs something that is true or false, which would depend on what the actor inputs for the system. The use of activity diagrams is another way to add more detail to use cases. These show the flow of activities that the system will process, which work well when more complex system is in place. The last one is using the system sequence diagram, which is a diagram showing the sequences of messages between en external actor and the system during the use case or scenario (Satzinger, 2015).

What is the primary objective of systems design? The primary objective of system design is to analysis to thoroughly understand the organization’s informational needs or requirements to set the specifications (Satzinger, 2015). This system design is to structure the components of the final system, which serve to distributed the type of environment the user will do. When looking at application software components within the system design, the analysis needs to figure out the sub systems, and relationships to each part of the

    This phase is the main focus of the project managers and stake holders. Meetings with managers, stake holders and users are held in order to determine the requirements like; Who is going to use the system? How will they use the system? What data should be input into the system? What data should be output by the system? These are general questions that get answered during a requirements gathering phase. After requirement gathering these requirements are analyzed for their validity and the possibility of incorporating the requirements in the system to be development is also studied.

Successful projects prepare for change by noting the flexibility of influencing factors and their likelihood of change, characterizing interactions among the factors and their impact, and selecting cost-effective design strategies to reduce the expected impact of the changes. Some categories of influencing factors are considered during global analysis: organizational, product & technological. Global analysis goes just examining requirements . It includes technological and organizational factors. Global analysis method consists of two phases: Analyze factors and Develop issues

    There are different types of UML diagrams. Each UML diagram is designed to let developers and customers view a software system from a different perspective and in varying degrees of abstraction. UML diagrams commonly created in visual modeling tools include: use case diagram which displays the relationship among actors and use cases. Class case diagram models class structure and contents using design elements such as classes, packages and objects. It also displays relationships such as containment, inheritance, associations and others. Sequence diagram displays the time sequence of the objects participation in the interaction. This consists of the vertical dimension (time) and horizontal dimension (different objects). Collaboration diagram displays an interaction organized around the objects and their links to one another. Numbers are used to show the sequence of messages. State diagram displays the sequences of states that an object of an interaction goes through during its life response to received stimuli, together with its response and actions. Activity diagram displays a special state diagram where most of the states are action states and most of the transitions are triggered by completion of the actions in the source states. This diagram focuses on flows driven by internal processing.

    Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also

    Information Retrieval is simply a field concerned with organizing information. In other terms, IR is emphasizing the range of different materials that need to be searched. Others researcher said that IR is the contrast between the strong structure and typing a database system with the lack of structure in the objects typically searched in IR. The actual process in information retrieval systems is it has to deal with incomplete or under specified information in the form of the queries issued by users. IR uses the techniques of storing and recovering and often disseminating recorded data especially through the use of a computerized system.
