The Elements of a Web Design

Designing of website is related to how your website looks like rather than how it works.  A designer has the following Responsibilities.

User Interface Design

It is important to identify the goals of a website.  The responsibilities of a web designer includes

Interaction Designer: Makes site available, easy to use, Interactive and Delightful to the user.

User Interface Designer: Makes user friendly navigation, buttons and other contents on the page. Focus more on the interoperability of website.

User Experience Designer: User experience designer focuses on the website development needs and requirements of the users based on interviews and statistics.

User Research

User experience is the first thing that can make your website successful. For your website to be successful, you must conduct research on user’s requirements and their tastes. After this you must conduct some user testing to check the performance of your website. You must create research and test reports after every test.

Diagrams

Mostly wireframe diagrams are used to describe the structure of your website. It defines the division and partition of the screen.

Site Diagram

Usually described by sitemaps, a site diagram, that is used to describe the structure a site along with the location and relation of the different pages.

Storyboards and User Flow Charts

Storyboards are used to describe the paths and tasks on the website. It describes how the tasks are done and how different applications are linked to each other. Flow charts are another way to represent storyboards.

Visual Design

Visual design describes the colour, theme, layout and structure of a website. Visual designer usually uses sketches to describe the design of a website. Visual designing is another part of graphic designing. You must have strong knowledge of CSS and HTML to become a visual designer.

Web development and Its Important Parts

Website presents you and your idea in front of all over the world through internet. Many companies in the world are doing their businesses through websites. Website plays an important role in the success of every online business. The main feature of any website is to provide the awareness and attract the attention of online users. Web is providing new offers, information and benefits of their products to the online users. Web development provides us a platform through which a developer can create a web solution according to requirements.

Now a days, lot of technologies used in web development. PHP is one of them. It stands for Hypertext Preprocessor. It mainly focuses on server side scripting. This technology is used in creating web pages which brings interactivity with the users. 

Many important parts are involved in web developments. But very basics are

1. Front-End
2. Back-End
3. Database

Front-End

Front-End is the application which users interact directly. It is like layer between user and Server side.

Almost always depend on the combination of HTML, JavaScript and CSS. Usually, HTML describes the content of the page, JavaScript identify the functionality, and CSS better defines the style, design and layout, There are various template engines HTML and CSS, either about the client side (the browser), or very about the server side (the Back-End). It's mainly a business of personal taste. There are many libraries for JavaScript as dexterously. JQuery allows you to be aggressive towards the page easily.

Back-End

Back-End means Server side. It supports the Front-End. If a user writes the address in address bar and then press it. The whole new page will be opened. Basically, User sends the URL to Server Side and Server return the webpage related to that URL.

Back-End or Server side code will get the files and data. This is depends on different languages like PHP, C#, Java, JavaScript, and different web development frameworks. They all have almost common functionality and libraries.

In the past, logic and functionality of the website were implemented on the Server Side. But now a day, web apps need to be very fast and responsive. Today web apps offer great functionality on the Front-End without refreshing the page. Some newer web apps are inclined towards Server side and think upon Client Side.

Database

Database is information which is organized so that it can be accessed, deleted and updated. Databases are used to permanently or temporarily store data. There are different types of database like relational database, documented database etc. The type of data you need to store and different operations you need to make on the data. Different languages used different tool to store the database.

Contents which they approved are totally user friendly. Content is still the King. Keyword plays a very important role in increasing traffic to a website.

A Structured approach to Software Developmet

Software development is the process of programming, testing, debugging and maintaining an application that results in software product. Software development is step by step method. Different methodologies are used for the development of software e.g. AJAX and Waterfall approach.

Software is developed for variety of purposes but the main purposes of software development are to meet specific need of a user’s.

 Software Development Methodology

There are variety of software development approaches are being used by developers but each of the methodology has its own strengths and weaknesses.  Software development methodology is a structured and well-engineered process. Most methodologies share the combine stages that are

·         Requirement Analysis
·         Planning
·         Designing
·         Coding
·         Testing
·         Deployment and Maintenance

·         Requirement Analysis Phase

Requirement analysis is the phase in which requirement engineers determines the needs or requirement for the development of new or altered product. Different requirements of different stakeholders can conflict with each other. But it is a task of an requirement engineer to analyse, document, validate and manage the software requirements.

Requirements can be of different types:

·    
·         Architectural Requirements
·         Structural Requirements
·         Behavioural Requirements
·         Functional Requirements
·         Non-functional Requirements
·         Core Functionality and Ancillary Functionality Requirements
·         Performance Requirements
·         Design Requirements
·         Derived Requirements
·         Allocated Requirements

Planning Phase

During planning phase you decide what you want to do, what is the problem and what is its solution. In planning phase we define the scope of our project or product. The basic activities that are involved in planning phase are:

• Define the problem, propose its solution and identify the resources and capital required.
•  Generate alternative solutions.
• Picking up a good development strategy that helps your product beat your competitor’s product.

Design Phase

Once the requirements have been gathered and resources and other capitals are defined. The next step is to produce the initial design of your product.

It is also called logical designing. In design phase we design the system architecture that helps has evaluate the software and hardware requirements also. Design development can be done in variety of ways some of which are Data Flow Diagrams, UML schemas, Prototyping and Diagramming.

Coding Phase

Coding of design is done in a computer language. In coding phase, all the code is written and then run on computer. If Hardware is required, hardware configuration is done. The product or project is prepared to run in an operational or user environment.

Testing Phase

Different components of the system are integrate together and then testing is applied on individual components and subcomponents. A component is tested by giving different inputs and the resulted outputs are then recorded in order to deduce results. Testing have different types, some of them are Black box testing, White Box testing, Integration testing and Load testing.

Deployment and maintenance

After the successful testing product is then delivered to the customer for their use. Deployment usually Includes Customization and Installation. Maintenance is the process of checking product’s faults and drawbacks and improve it for the future use. Maintenance is the process of evaluating System’s performance.

How Software Engineering describes Data Modeling?

A data model is generally formed to illustrate the structure of the data handled in information systems and persevered in database management systems. In term of software engineering, the data model basically describes the structure of data entities and their associations. If we consider an example of banking system, entities will usually incorporate Customer, Account, and Loan. Entity of “Account” has a number of attributes, for example account number, type of account (either it is savings or checking), current balance, and status. A relationship may state that one customer can have one or more accounts (one-to-many relation), and/or one account is linked to one or two customers (in joint account).

Data modeling in software engineering is the documentation and formalization of some existing processes and procedures that occur during software and web designing and development. Data modeling methods and tools capture and transform complex layout of any system into easily understood illustrations of the data flows and processes, creating a blueprint for structure and/or re-engineering.

Software engineering data modelers frequently use several models to view the same data and guarantee that all procedures, data flows, entities, and relationships have been recognized. There are quite a lot of different approaches to data modeling, including:

•  Conceptual
• Enterprise
• Logical            and
• Physical

Conceptual Data Modeling identifies high level relationship and properties of different types of entities. It is the best modal suitable for communication between stakeholders.

Enterprise Data Modeling identifies the unique requirements of a specific business having the similarity with conceptual data modeling.

Logical Data Modeling describes the specific relationship, attributes, and entities of a business function. It is also creates the basis for physical data modeling.

Physical Data Modeling describes application representation and specific implementation of database of logical data model.
