Hello friends! From this post we are going to see how to draw a class diagram. In the end of this post you can draw a class diagram by yourself. If you still don't know how to draw a class diagram, then this is for you. Carefully read the whole post. Don't worry we will start from beginning. How do you draw a class diagram. For that you have to learn first the components. What are the components of a class diagram. Or What…
Hello readers! Hope you doing good. Today we are going to learn about how to draw usecase diagrams. Which is a one of UML diagram. For software engineering we use this diagrams. Software engineering is not just coding. There are so many other things also. So let's get started. We will start the post with learning what is usecase diagram and why. Firstly we will learn why we use usecase diagrams. Why use case diagrams Firstly we will see what is the use of…
Hello students, today we will discuss about software maintenance. Software maintenance phase starts after testing phase and after product has handed over to the customer. These changes are not very huge changes. They are minor changes. Software change with the time is a something actually happening because of that we need software maintenance. But with the time software can have major changes. So we can accept them any change request. Now let's see what are the things that leads to software maintenance phase. Reasons…
Testing phase starts after the development phase. Here system or software will be tested in advance. There are so many testing types that done during this phase. There is a order for doing those testing types. Software testers or Quality Assurance team will be responsible for this phase. This make sure software is met all the requirement that customer requested and is it functioning without bugs. There are testing frameworks as well as testing software. In the testing phase test cases are the most…
Hi friends with this post we will discuss about development phase of SDL. Firstly just remind what do you know about development phase. Not much. Don't worry we will learn about that. Actually when we discuss about development phase we have to talk about coding. In this post we mostly discuss about coding practices. Development phase is carried out after the design phase. https://myexamnote.com/design-phase/ Development phase is the longest phase in the software development. There all the functions will be implemented. This task will…
Hello students! today we will discuss about software design phase. Firstly we will see what is mean by software design. Now think you need to design a birthday card for your friend's birthday. What you will do. You will think about the paper colors you going to use, pens, stickers, what is the shape of card those things right. So as it is in software designing we also do the same thing. We design software architecture, infrastructure, user interfaces, database these things in design…
Requirement gathering and analysis is the second phase of the development cycle. Business analysis takes ownership in this phase. There are so many things happens in this phase. In this phase BA met the customers and gather the requirements for the software. Firstly we will see what is requirements. Requirements are two types. Post outline What is a requirementThe life cycle of requirementsWhat are functional requirementsWhat are non-functional requirementsDomain RequirementsFact gathering Techniques for Requirement gathering and AnalysisWhat is the requirement EngineeringPhases of requirement gathering…
In this phase we check if we can do the project successfully. As an example it checks, do we have the resources for the completion of the project. There are several feasibilities. We check them before project starts. In this Analysis we also do the SWOT analysis and find what are the strength and weaknesses. There are so many techniques that we used to do feasibility study before that we will learn what are the feasibilities that we are checking. Firstly we learned what…
Hello guys! Today we are going to talk about SDLC - Phases of SDLC and Overview. SDLC stands for Software Development Life Cycle. As humans we also have a life cycle. In our life cycles we go through different stages. We have different changes to ourselves through that life cycle. We grow, we can do more activities are some of them. Same thing happen in SDLC, In that is also having the stages that software went through. During those stages also software evolve as…
