An actor is shown as a stick figure in a use case diagram depicted "outside" the system boundary, as shown in the below figure. A use case in a use case diagram is a visual representation of distinct business functionality in a system. The key term here is "distinct business functionality. As the first step in identifying use cases, I should list the discrete business functions in my problem statement. Each of these business functions can be classified as a potential use case.
I have to remember that identifying use cases is a discovery rather than a creation. As business functionality becomes clearer, the underlying use cases become more easily evident. A use case is shown as an ellipse in a use case diagram. System boundary: A system boundary defines the scope of what a system will be.
A system cannot have infinite functionality. So, it follows that use cases also need to have definitive limits defined. A system boundary of a use case diagram defines the limits of the system.
The system boundary is shown as a rectangle spanning all the use cases in the system. Use Case Diagram of all kinds of lectures Fig: Process models have been a part of structured systems analysis and design techniques for many years.
A process model describes business processes—the activities that people do. This chapter describes data flow diagramming, one of the most commonly used process modeling techniques. DFDs consist of four major components: The symbols used to depict how these components interact in a system are simple and easy to understand; however, there are several DFD models to work from, each having its own symbology.
DFD syntax does remain constant by using simple verb and noun constructs.
Such a syntactical relationship of DFDs makes them ideal for object-oriented analysis and parsing functional specifications into precise DFDs for the systems analyst There are many different process modeling techniques in use today.
In this chapter, we focus on one of the most commonly used techniques data flow diagramming. Data flow diagramming is a technique that diagrams the business processes and the data that pass among them. DFDs are easier to understand by technical and nontechnical audiences 2.
DFDs can provide a high level system overview, complete with boundaries and connections to other systems 3. DFDs can provide a detailed representation of system components. DFDs help system designers and others during initial analysis stages visualize a current system or one that may be necessary to meet new requirements. Systems analysts prefer working with DFDs, particularly when they require a clear understanding of the boundary between existing systems and postulated systems.
DFDs represent the following: External devices sending and receiving data 2. Processes that change that data 3. Data flows themselves 4. Data storage locations The hierarchical DFD typically consists of a top-level diagram Level 0 underlain by cascading lower level diagrams Level 1, Level 2… that represent different parts of the system. We begin by making a list of business activities to determine the DFD elements external entities, data flows, processes, and data stores.
Next, a context diagram is constructed that shows only a single process representing the entire system , and associated external entities. The Diagram-0, or Level 0 diagram, is next, which reveals general processes and data stores. Following the drawing of Level 0 diagrams, child diagrams will be drawn Level 1 diagrams for each process illustrated by Level 0 diagrams.
Register 1, Exam 2, and Graduate 3 are the processes in the program.

Student Record is the data store. Register 1 performs some task on Registration Form from Student, and the Subject Registered moves to the data store. The Class Rolls information flows on to Faculty. The diagram describes data flows into and out of the system and into and out of external entities. External entities are items such as persons, places, or things outside a system that send data to, or receive data from, a system.
The system provides the semester specific information like the academic year, semester, courses offered and their sections. The system filters out those courses that cannot be selected by student since they are not part of the curriculum or their pre-requisites are not satisfied. The repeat courses are specifically highlighted. The student makes course selections. The repeat courses are directly added by the systems. The student makes corrections to the course selection. Process-1, Select Courses The student provides which of the courses, sections, and lab groups are preferred.
The system checks the course selection to see if the rules and regulations credit restrictions, prerequisites and collisions are applied. If so the Registration Form is produced and stored. Only, the repeat courses cannot be removed and the rules and regulations are applied at each time.
Figure 4: Process-2, Approve Registration The student approves the course selection at any time. After the approvement, the system prevents any changes to be done by the student.
Each rejection is explained by the Advisor. If the Advisor rejects some courses, the student shall select new courses instead. After the approvement of Advisor, the registration form is locked against any modifications.

Level-0 DFD: Process-3, Filter Offered Courses: Student's curriculum is compared with the offered courses to find out which of the offered courses match courses listed in curriculum.
The matched ones are specially highlighted. Other semester courses of the student are provided to the student with their section and lab groups. Process-4, Get Semester Specific Info: The academic year and semester information is received from the Academic Year Management System. Student's advisors are received from the Advisor Management System.
Courses offered with their section, lab group, and scheduling information is received from the Course Offering System. The information is stored for further usage. Below is a checklist of points to watch out for before moving on to a detailed investigation which will take us to lower levels. I am flowing: So I did not create complete DFD diagrams in one page.
I have showed DFD diagrams as block wise So that I can understand every step and features of system part by part. And admin, teacher, student should login 1st to access in every block. During the analysis phase, the data model presents the logical organization of data without indicating how the data are stored, created, or manipulated so that analysts can focus on the business without being distracted by technical details.
Later, during the design phase, the data model is changed to reflect exactly how the data will be stored in databases and files. This chapter describes entity relationship diagramming, one of the most common data modeling techniques used in industry. An entity relationship diagram ERD shows the relationships of entity sets stored in a database.
An entity in this context is a component of data. In other words, ER diagrams illustrate the logical structure of databases. At first glance an entity relationship diagram looks very much like a flowchart. It is the specialized symbols, and the meanings of those symbols, that make it unique.
An ER diagram is a means of visualizing how the information a system produces is related. There are five main components of an ERD: An entity is an object or concept about which you want to store information. A weak entity is an entity that must defined by a foreign key relationship with another entity as it cannot be uniquely identified by its own attributes alone. In some cases, entities can be self-linked. For example, employees can supervise other employees. A key attribute is the unique, distinguishing characteristic of the entity.
For example, an employee's social security number might be the employee's key attribute. A multivalued attribute can have more than one value. For example, an employee entity can have multiple skill values.
A derived attribute is based on another attribute. For example, an employee's monthly salary is based on the employee's annual salary. Expand all: Logical view Fig: A successful design builds on what was learned in earlier phases and leads to a smooth implementation by creating a clear, accurate plan of what needs to be done. This chapter describes the initial transition from analysis to design and presents three ways to accomplish the design for the new system.
Many activities will be involved as the development team develops the system requirements. This chapter provides an outline of those design phase activities. The purpose of the design phase is to decide how to build it. It spans the life cycle from initiation of acquisition through sustainment and is focused on highlighting and managing risks to a successful outcome.
Developing an acquisition strategy is a key component of acquisition planning. In fact, there are thousands of commercially available software programs that have already been written to serve a multitude of purposes.
All software which has been used for this project has been given bellow: Xampp 2. NetBeans IDE 3. Edrow Max 7. I want to do this project by myself and I want to increase my ability on software development technology.
So I do not want any outsourcing for help. So I am perfect to do the project. Because I am a current student of the institute. If software development is a core competence for the company, it generally leans toward in-house software development, which stands for the development taking place onsite.
Usually in-house software development makes sense for companies that have enough resources and favourable infrastructure to develop software on their own.
According to my ability and my resources, I am able to do my project in house. Because I have some experience to do that type of project before. I have already done 5 projects by myself where 3 project were web application. And this project web application too.
As I have some experience on website design and development, I can use my skill on this project. I can handle programming, design, and development too. The architecture design flows primarily from the nonfunctional requirements, such as operational, performance, security, cultural, and political requirements. The deliverables from architecture design include the architecture design and the hardware and software specification. An important step of the design phase is the creation of the architecture design, the plan for how the information system components will be distributed across multiple computers and what hardware, operating system software, and application software will be used on each computer e.
In this section, we first discuss the major functions of the software to understand how the software can be divided into different parts. Then we briefly discuss the major types of hardware onto which the software can be placed.
Although there are numerous ways in which the software components can be placed on the hardware components, the most common architecture is the client—server architecture, so we focus on it here.
JNTUA B.Tech 4-1 Syllabus Books R15 CSE, ECE, EEE, IT, Mech & Civil pdf
The major software components of the system being developed have to be identified and then allocated to the various hardware components on which the system will operate.
Each of these components can be combined in a variety of different ways. Architecture design is very complex process that is often left to experienced architecture designers and consultants, but we will give a sense of the process here. This usually refers to operating systems, system software, and information systems with which the system must interact, but will on occasion also include the physical environment if the environment is important to the application.
As analysts define the performance requirements for the system, the testability of those requirements is a key issue.
Each requirement must be measurable so that a benchmark comparison can be made. Only in that way can the achievement of a performance requirement be verified. I am trying to solve those security requirements bellow: It includes the screen displays that provide navigation through the system, the screens and forms that capture data, and the reports that the system produces whether on paper, on the Web, or via some other media.
This chapter introduces the basic principles and processes of interface design and discusses how to design the interface structure and standards. After analysis user I found that four types of users will use this website. It is not possible to show all interface at a time. So I am showing user by user interfaces which will be used most of the time. Those principle helped me a lot to complete the design part. So I am going to show a list of principle which is used for interface design.
Principles for User Interface Design are: So I need to use those principles correctly. In the bellow I have shared some process of interface design. User Interface Design Process are used: They do not required id or password.
This page is the layout of home page. This is so large page so I am showing it part by part. This page will contains header, footer, notice board, news, events, motivational video, links of all other pages in header etc. From home page, users can access directly the information pages like admission, program, tuition and cost etc. Academic, housing, teachers, e-library, research page links contains here.
Home page part 2 Fig: For public user we are seeing that after clicking information 11 links are showing like admission, program, requirements, academic, tuition etc. Here admission process and information are included. Admission home page Fig: After that, user will just click on his program, it will show all requirements information of that program selected.
Admission requirements page Fig: Here GPA requirements and other requirements will show. Admission requirements details page Fig: After that tuition and cost home page will display.
And then user can see detail information. Viewing Tuition and Cost home page Fig: Students who will take new admission need to know admission test information. By clicking specific program area from the above page, user can view details admission test information. The next page is showing the details admission test information for both written and viva test.
The page is showing admission session and schedule home page. Admission session and schedule home page Fig: Please see the next page. Admin will upload result sheet and students can download and view those result sheet. The next page is showing admission result sheet list trimester wise. The layout for admin and public user is same. So you can see the admin layout here. In this page admin can view, edit and delete result file. Though the layout is same, public user can view and download result sheet only.
For doing this special function and programming logic is used. Admission result sheet view home page Fig: He will re-directed into admission test result sheet link with simple description. What is showing? Please see next page. That means viva is not taken yet. The next page designed for showing facilities of our cse department.
From this one page students will understand about our CSE department and its facilities. Please see in the next page. Academic page contains academic policy, academic calendar, credit transfer, team of faculty and academic excellence information. Academic Home Page Fig: I think student will feel lucky for this website.
Because this website will help them in many ways. We can see on the page here that it is showing three option for sign up. The sign up options are: Teacher 2. Students 3. The next page will show account activation and sign up page. Signup page home Fig: Activation pin code and teacher id will be probided by admin. And session will start automatically. He also can use Information and e-library link from above the header.
Suppose a students want to read academic book from e-library or he need to download a book. After clicking on that link E-library home page will show up. Please watch the next layout of e-library. E-library will contains most recent book, shorting books by type, books by category, books by alphabetically.
A student and a teacher can be able to download, view any pdf book from the library. Students will also see full profile of any book. Student can also view books by type or category from the link bellow: Complete layout of e-library of my departmental website has been given in the next page. Let see an example with a layout, a student clicked on the title Pro Java Programming. He will re- directed into book profile details page. Book profile contains title, edition, content, type, category, authors name, publishers information etc.
Please see the next layout. And in the right bar student can see notice, news, events. The picture is showing the link of Public lecture link in the left side. It has appeared when student clicked on View lecture link.
Please see the page bellow. After clicking in the link VIEW, student will see more link like profile view, schedule, courses, my group, result view, notice board, news, event, view lectures and home page link.
Please watch at the next page. The schedule home page has been organized by trimester, schedule type, category and more. And now we can see the schedule home page which has been given bellow. At the next page schedule home page has been shown and after the next page I have shown students home page as mobile view. I design all user interface mobile friendly so that student and teachers or other user can use this website by mobile, laptop or computer.
Any schedule can be download from here. And this interface layout for mobile user.
Online Course registration is an important features for my project. After that, click on online course registration link. Please see the next fig. A student can know about which course offered for which batch. A student is permitted to take any course from the list. Maximum 9 course will be accepted.
And if someone try to take more than 9 course it show a massage that he has already taken 9 courses. When a student will click on his batch, a course list will be shown which will contains the information like course Title, credit hour, trimester year, course teacher name, course pre-requisite with Take This Course and View Full Profile link.
I think every student should view course outline and full profile of a course before taking that course.
After viewing the course outline or profile student will understand about the course. After taking courses for new trimester, list of taken recent courses will be shown at right side of home page.
Please see next 3 page. A course profile layout, home page with taken course list and take a course page given bellow: We are watching my recent courses at right side of the above page.
We are also watching some information like summer, course list, credit hour, total credit hour. For what is this button? Actually after taking any course and after accepting that course by teacher, a student is permitted to enter the course wise group which is created automatically. Creating course wise group is an automation. After viewing course full profile, I have shown and described about course wise group. So please see at the next page.
Course wise group is one of the most important features for my project. This features will help academic student and teachers a lot. All course which has been taken at summer by the student will be shown.
Please watch at next image: This is group home page. This page will contains course title, course teacher name, post massage, view massage, download, add, edit delete lectures, complete course outline and profile, simple video for course, video lectures.
Student and teacher will massage each other from thus group. Teacher will upload lecture pdf, ppt slide lecture, doc file, video lecture etc. A teacher can make his lecture public or privet. Privet lectures can be downloaded by group student and members. And public lecture will be downloaded by all academic student.
From massage board, student can edit, view, and delete his own massage. Please see massage board in the next page. Like those next screen picture. The system will allow for the student for limited time. But if new trimester course offered, he will fail to delete the course. After upload complete live picture will be shown. To complete editing profile picture, student should click on button save image.
We already have seen that we can download lectures from our group. But there are a lot of students who are so advanced in their education. They want to know and study of their upcoming courses. So they want to get lectures before new trimester start. For those student I have made lectures home page. From this home page student will download all public lectures. The lectures which has been made public by subjective teacher. At lecture home page, all lectures are organized and shorted by session, trimester, and teachers.
To do this I also have used slide show.
Please watch next page. This page will contain all links of other pages. At right side of the page, teacher will see most recently offered courses by him, notice, and news. At middle side, teacher will view most recent post, and a system to offer new course. He can be able to post massage directly from here. From the left sidebar, teacher will redirected into home page of my group, add lecture, view student, result entry, lecture entry, offer new course.
To offer new course, a teacher must be provided a batch as advisor. Teacher will select trimester, trimester year, course teacher. And then he will offer the course for his batch. After offer the courses, the courses will be added to recently offered course list and to the batch whom he is advising.
When teacher will offer course, a list of recent course offered by him will be shown at the right-side of the page. After that students will take new course and will sent request for acceptation.
From the above page, we are watching that a advisor can accept and delete any students registration request.It is combining elements of both design and prototyping-in-stages, in an effort to combine advantages of top-down and bottom-up concepts. I must be aware of potential risks so that problems can be avoided or controlled well ahead of time.
Introductory Quantum Chemistry. In this Word eBook, you will look at each of the Tabs in turn. Computer Science and Information Technology Digital Logic: Logic functions, Minimization, Design and synthesis of combinational and sequential circuits; Number representation and computer arithmetic fixed and floating point.
Ocean chemistry and deep sea sediments. So I am going to show some list which can be added in this website. The strategic alignment of the project and a stakeholder analysis can be used to assess this feasibility dimension. Electronics Engineering.
