It is said that the concept of design patterns has its origins in Field Architecture. It can be defined as a reusable solution to a problem occurring (commonly) in software design. In the mid-80s, experimentations began to apply patterns to software programming, and it has continued to evolve and be used regularly since. This is no surprise, as there are quite a few benefits to it. With design patterns, you can speed up the development process, prevent small issues from coming up later, improve code and cut down on the cost of developing the software.

There are basically three categories of design patterns:


Class instantiation forms the basis of this design pattern. Creational pattern can be further divided into class-creational and object-creational patterns. In the former, inheritance is used by subclasses to determine the type of class instantiated, and in the latter, instantiation is delegated to the objects. Some examples of this type of pattern are Prototype, Factory Method and Object Pool.


In this type of pattern, classes and objects are used together to form larger structures. While, structural class pattern relies on inheritance to compose an interface, structural object pattern uses different objects to create a new functionality. Proxy, Adapter, Bridge and Private Class Date to name a few come under this classification.


Here, the is a focus more on algorithms and there is attention given to the communication between patterns. The behavioral pattern can be differentiated into a behavioral class pattern and a behavioral object pattern. In the first, inheritance is used to assign behavior among the classes, and in the second, object composition is used. Command, Template Method, Strategy and Interpreter come under this type of pattern.

There is a fourth and ‘not so popular’ type of design pattern, Concurrency pattern. Thread Pool, Thread Specific Storage and Read-Write Lock are examples of this.

While we have mentioned many design patterns that are used quite commonly, it is by no means a complete list of all available patterns. Some patterns have become more popular over time and have found a lot of use, when compared to others.

Though it is true that design patterns allow for the coding of stable and robust software systems, there has been some criticism as well. Namely, that it leads to inefficient solutions due to unnecessary duplication of code and can even target the wrong problem. All the design patterns come with their set of pros and cons. This makes it important to pick the right pattern to use. To do this, clearly identify and define the problem to be solved.

4 digital solutions to address common application performance issues

High network latency, memory leaks, slow page loads, heavy CPU usage, and unresponsive servers are all typical performance issues we’ve experienced at some point when using or accessing digital applications. With how easy they occur in projects across verticals, you might be wondering whether the development teams behind these programs have done enough due diligence prior to the release. But human errors and oversight aren’t always the culprit. The reality is that while developers can strive to develop a fully functioning program with virtually no apparent faults upon delivery, no software is truly error-free. Even the most rigorously tested applications

6 useful tips for creating more robust application lifecycle management

As digital technology becomes the norm, software acquisition is now key to gaining a competitive edge in today’s market. Be it as a value offering tailored to consumers or a productivity tool to run complex processes, custom software undeniably helps companies drive growth and deliver value more efficiently. Just as necessary as having a proprietary application is prescribing a standard procedure to govern and maintain its utility. This is to ensure that your business can develop or adopt the right type of software—one that can fully cater to your business needs while keeping disruption to a minimum across critical milestones.

5 major roadblocks businesses must overcome when transitioning into a new software environment

As the business landscape becomes increasingly saturated, staying ahead of the curve often means embracing disruptive technologies to meet the fickle market demands. In most cases, this entails knowing when to pivot your current strategy to an entirely new solution. But recognizing the importance of digital shift is one thing; implementing the necessary IT upgrade is another. A global survey by Deloitte has found that although 87% of companies manage to identify the impact of digital trends on their industries, only 44% have adequately prepared for the coming disruptions. This vast disconnect between organizational expectations and conditions in the field

Is cloud computing the answer to better software development?

Cloud computing is perhaps not a term often heard in daily conversations, but it is one with a far-reaching impact on our technological needs. From expansive options of online data storage to numerous suites of web-based productivity tools like Google Workspace, nearly everyone has used a cloud-enabled technology. Over the last decade, this high degree of versatility also underpins the rapid cloud uptake among businesses. In fact, one survey has found that 94% of companies have already shifted their computing workloads on cloud platforms to varying extents. Unsurprisingly, the market size for cloud technology continues to grow exponentially. With a
