“During the object-oriented analysis (OOA) phase object-modeling techniques are used to analyze the functional requirements for a system and create models which reflect the logical design of the system. During the object-oriented design (OOD) phase of the system, models are elaborated upon to include implementation specific details that show how the physical design of the system will come together. OOA focuses on what the system does (its static structure and behavior), OOD on how the system does it (its run-time implementation).”
You work as a junior technician in a small organization, Salchester PollUTest, which has recently started up following a split from a parent company. The managing director of the new organization, Gary, is looking to enhance the basic computer system that he currently has.
The systems development life cycle (SDLC) is a structured methodology and process that guides the development of information systems. SDLC is based on a series of related activities that are combined into phases, sometimes called life-cycle phases. The phases represent a state or stage in the life of an information system. Generally speaking, an information system life cycle proceeds from requirements gathering to
This method of programming has allowed developers to create more complex systems or applications. The smaller pieces or modules can be tested easier and created by different developers at the same
So to see the scope of the two is to go into detail of what each does and how they function. Now Procedural you will provide step by step instructions and the program will run through everything throughout the process and solve the problem. Procedural was mainly used in the earlier programming languages, like COBOL or C (Gaddis, 2016). Object-Oriented languages use a different way of
I am writing to find out whether writing programs in a block programming environment is more effective compared to a high level language. I will look at both block programming environments and high level languages by researching and explaining what each of them are but also by giving examples of programs made using them and by focusing on both the advantages and disadvantages of writing programs in these ways. I will compare the two together and decide whether they are suited to complex or simple situations and also as well as this will look at whether the programmer needs knowledge on how to create a program using them.
The term cohesion is used to indicate the degree to which a class has a single, well-focused purpose. Cohesion can be applied to classes and methods which should display a high degree of cohesion.
Definition: The System Development Life Cycle describes functions and activities that system developers perform typically, without considering how those functions and activities actually used in that particular methodology. SDLC denotes a set of general categories that show the major steps, of system development project. These are different phases in SDLC which each of them can be used to denote a step of the process that is followed in the development of certain system. These phases remain same at all the time for different systems as they are the basic steps.
Ans: a) In procedural program, programming logic follows certain procedures and the instructions are executed one after another. In OOPs program, unit of program is object, which is nothing but combination of data and code.
A procedural programming a program that contains a series of computational steps to be carried out. Procedural programming is a term to denote the way in which a computer programmer writes a program. This program works by using sequences of instructions. The types of procedural programming are pascal, c++ and c.
Similarly, modular programming is a software design technique that encourages separating functions of a program into individual, reusable modules, in that each module contains everything necessary to perform a single desired function. Phew!
String of a language is known as Sentences or Statements. Syntax rules of the language specifies the strings of characters from the language alphabet. The example of a natural language has a large and complex collection of rules for specifying the syntax. While comparing with the programming languages are syntactically very simple. The Formal descriptions of the syntax in programming languages are very simple to achieve and it does not include descriptions of lowest-level syntactic units. These small units are known as
Software development life cycle (SDLC) can be termed as a process of bringing ideas to reality in the creation of a software product with in the software industry.
