Introduction: At a technical level, software engineering fundamental activities are Software specification, software development, software validation, and software evolution. The analysis model is a set of models and first technical representation of the system. Several methods have been proposed for analysis modeling. The two common and well known approaches are as follows: Structural analysis is a building model which determines the data ( their attributes and relationships) and the processes that transforms the data. Object-oriented analysis based upon the concepts of Classes and their inter-relationships. Its objective is to satisfy the customer requirements. Analysis Model is an important …show more content…
This information can be understood and manageable by the software. These data objects can be printer, user, sensor which is external entities. Things in the form of reports, displays etc. Events like interrupt, alarm. Specific role in the firm like manager, engineer, salesperson. Firm units e.g., division, team. places e.g., manufacturing floor workshops. Structures e.g., employee record, student record,accounts, file. Let us take an example of data object Vehicle which has the following attributes Make, Model, Color, Owner and Price. Each instance of data object can be identified by unique identifier like in a university student is recognized by its Roll number. Attributes: The properties of data objects are defined by attributes. These can be of three types Naming attributes, Descriptive attributes and Referential attributes. 1. Naming Attributes: These attributes are used to name an instance of data object. For example in a Vehicle data object make and model are naming attributes. 2. Descriptive Attributes: These attributes are used to describe the characteristics of a data object. For example in a Vehicle data object color is a descriptive attribute. 3. Referential Attributes: These attributes are used in making the reference to another object in a table. For example in a Vehicle data object Owner is the referential attribute. Relationships: It represents the connection between data objects. For example the relationship between shopkeeper and a
o The terms of the classification tell us what the individuals in that class have in common.
In an effort to classify what sort of things properties are several possibilities have been introduced. The favorite theory of D.M. Armstrong was that of properties as universals. Armstrong beliefs that universals are an ontologically basic component of the world. He compares them to the letters of the alphabet, rather than the words. Universals are thus a basic component of things. Armstrong also made several other claims about universals. First universals must be sparse. There isn’t a universal corresponding to every set. There are only as many universals as there are genuine similarities. Every universal must also be instantiated by something, either in the past, present or future.
To put it another way, properties are what make up an object, and substance is what the

What is the difference between class characteristics and individual characteristics pg. 146? The differences of these two characteristics is that class characteristics are the evidence that has characteristics of objects that cannot be traced back to a particular individual, like soil, glass, and paint. And for the individual characteristics are the evidence that has characteristics that are unique objects that allow for comparison of evidence to a specific person and can be traceable to find the individual that include their fingerprints, palm prints, and footprints.
...oth of software and hardware that analyze different data and transformed them to information about people.
8.) Data - means facts or information. People use data as a basis for drawing conclusions about the topic or theme they are studying.
distinguishes a tie between people that will provide that interaction as well as keep the interaction consistent on a regular basis.
A database is a structured collection of data. Data refers to the characteristics of people, things, and events. Oracle stores each data item in its own field. For example, a person's first name, date of birth, and their postal code are each stored in separate fields. The name of a field usually reflects...
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

Requirements engineering begins during the communication activity, continues into the modeling activity, and builds a bridge from the system requirements into software design and construction. Through requirements engineering, there is an examination of the context of software work performed. It is essential for the software engineering team to understand all requirements of a problem before the team tries to solve the problem. An identification of specific needs that the design and construction must address is also included. Further is a need for the identification of the priorities that guides the order for the completion of work. This i...
An association matrix is chart made up of rows and columns depicting every relationship that an individual has. Information is taken from investigative reports, public records, and testimony. Each person that is associated will also have as many known other relationships as well.
Software engineering is important in today’s society because we use the products of software engineering almost daily. We use the products of software engineering in objects as simple as our car keys to objects as complicated as supercomputers. The past, present, and future of software engineering is quite interesting. This paper will provide information about this field of study and why software engineering is going to be around a while.
