3 types of application software you should know

Software solution design process always targets the reuse of components and modules to speed up the development process, lower the project cost, and provide the customers with a faster valuable solution.

For any Software project initiation, mainly the solution architect think about if we already have a similar solution or application for the requested requirements or not. If it is possible to use some parts of the code or not. Maybe, we should search for ready-made products that we can use if a company or someone already developed this application and it satisfied our requirements.

Always, we will observe this kind of discussion for any project initiation and in solution architecture process.

In this article, we will discuss the 3 types of application software any software engineer, software project manager, technical sales, or architect should know.

How to visualize the software using effortless diagrams!

Software visualization is essential in the software development lifecycle to realize how the software will be conceptualized, visualized, structured, understood, and implemented. Software visualization can be defined as the art and science of generating visual representations for the various aspects of the software.

The purpose of the visualization is setting a common understanding of the system for all stakeholders, for example, business users, development team, architects, designers, …etc.

It is a part of Software architecture and design which usually needs problem-solving and planning. This may include both a low-level component, algorithm design, and a high-level architecture design. The image below can summarize the types of visualization in the software architecture, for example, if we would like to present a system of two components, it can be visualized by text visualization or graphical visualization. I think all of us can conclude that the software requirements specifications document can be a textual visualization of the system. I think yes but not only as part of this textual presentation should include the design decisions and may have pseudo code in some parts.

sample component

In this article, we will discuss different types of graphical visualization for the software that are commonly used in the software development lifecycle. Therefore, We will discuss the following diagrams and their usage:

  • Context Diagram
  • Use Case Diagram
  • Activity Diagram
  • Class Diagram
  • Entity-Relationship Model

Architectural Styles, Architecture Patterns, Design Patterns, and Language Idioms

If you attended any of Software Architectures classes or read any books regarding the Software Architecture, it is common to have buildings Architecture as an analogy to understand the main concept of the Software Architecture. We will use the same here to understand what is the style and what is the pattern

An architectural style is characterized by the features that make a building or other structure notable and historically identifiable. A style may include such elements as form, a method of construction, building materials, and regional character. Most architecture can be classified as a chronology of styles which changes over time reflecting changing fashions, beliefs, and religions, or the emergence of new ideas, technology, or materials which make new styles possible.

Database views for Rails performance optimization

Rails Framework is one of the greatest supporters for Rapid Application Development (RAD) which tends to abstract and simplify the web architecture so that Rails abstracts away the database through the Active Record which is the Object-relational mapping (ORM) for rails.

The Active Record is the layer of the system responsible for representing business data and logic. Active Record facilitates the creation and use of business objects whose data requires persistent storage to a database.

So, It helps in a way to manage all relations consistency and mapping in the class model without the need to write SQL statement to retrieve any data or the usage of CRUD (create, read, update, and delete) methods in general. Read more

Architectural Design Decisions

There is no doubt how the architecture is important to shape the solution and define its characteristics in the different architecture domains, and how this solution will be adaptable and dynamic to absorb new business needs and handle different stakeholders’ concerns.

In most architecture development processes, different decisions are taken in the different architecture domains. Architects may make different decisions, such as choosing a specific component, in the conceptual architecture and follow a specific architecture pattern.

Difference between Software Architecture, Software Structure, and Software Design

Introduction

Over the past 10-15 years, Software architecture has been widely spread in the software engineering community, To the extent that there are currently many career positions for software architect like Technical Architect and Chief Architect. Also, Architecture has involved in many different domains, for example, the architecture used to describe and refer to the internal structure of microprocessor and structure of machines or Network. For that matter, Trying to find one widely accepted definition for software architecture is not easy, and this issue has been introduced in many books when the authors start defining software architecture.
