What do you need to know about the Software Development phases

Software development life cycle models have different strategies and methodologies for the software development process and I wrote about the different types of development models, please review this article for more information, we also discussed how to select the most suitable model based on your project context.

Regardless, what model you have selected, these models are sharing mostly the same development phases with different arrangements, a more or a less phase. Furthermore, they can be implemented in an iterative and incremental model.

At this article, we will discuss the most common phases across all SDLC models. I will add other articles to discuss each phase in details 🙂 Read more

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

The best SDLC model

I received a lot of emails and comments regarding the best software development life cycle model. So, I had to write my opinion about that.

Actually, I think there is nothing called the best in absolute general, the best for me maybe not the best for you at this moment. Similarly, there is nothing called the best SDLC model in absolute general, you need to decide which one you need to use according to the software project context and what product or software you are developing, what about your competitors? And what are the team capabilities you have? Read more

“White Box” Techniques for security testing

“White box” tests and analyses, by contrast with “black box” tests and analyses, are performed on the source code. Specific types of white box analyses and tests include:

Static Analysis

It is known as “code review,” static analysis analyses source code before it is compiled, to detect coding errors, insecure coding constructs, and other indicators of security vulnerabilities or weaknesses that are detectable at the source code level. Static analyses can be manual or automated. In a manual analysis, the reviewer inspects the source code without the assistance of tools. Read more

Choosing the right Software development life cycle model

Selecting a Software Development Life Cycle (SDLC) methodology is a challenging task for many organizations and software engineers. What tends to make it challenging is the fact that few organizations know what are the criteria to use in selecting a methodology to add value to the organization. Fewer still understand that a methodology might apply to more than one Life Cycle Model. Before considering a framework for selecting a given SDLC methodology, we need to define the different types and illustrate the advantages and disadvantages of those models (please see Software Development Life Cycle Models and Methodologies).

Software Development Life Cycle Models and Methodologies

Introduction

Software development life cycle (SDLC) is important for the software project success, the good software engineer should have the enough experience and knowledge to prefer one model than another based on the project context.

Therefore, it may be required to choose the right SDLC model according to the specific concerns and requirements of the project. I wrote another article on how to choose the right SDLC, you can follow this link for more information.

In this article, we will explore the different types of models and the advantages and disadvantages of each one and when to use them.
