10 Things to Remember while doing Database Server Migration in Production

Hello guys, recently, I have to work on a high profile project which involves migrating a live database from one server to another server as part of their data center exit program. This was one of the critical projects to pull off because we can't afford any mishap or data loss or production outage. There are a lot of things that I learned and would like to share with you guys. All these lessons not just apply to migrate databases like Microsoft SQL Server, Oracle, or MySQL database from one server to another but to any production process, you are migrating from another server. These are the things we learn from experience but as I have said in the past, you can only learn a few things

Difference between Inheritance and Composition in Java and Object Oriented Programming

Though both Inheritance and Composition provide code reusability, the main difference between Composition and Inheritance in Java is that Composition allows reuse of code without extending it but for Inheritance, you must extend the class for any reuse of code or functionality. Another difference that comes from this fact is that by using Composition you can reuse code for even the final class which is not extensible but Inheritance cannot reuse code in such cases. Also by using Composition, you can reuse code from many classes as they are declared as just a member variable, but with Inheritance, you can reuse code from just one class because in Java you can only extend one class because multiple Inheritance is not supported in Java.

Why use Cloud Computing? Advantages and Disadvantages

10 Tips to create Maintainable Java Applications

Hello all, if you are in software development then you know that creating an application is easy but creating a maintainable application that can pass the test of time in production is rather difficult and that's the main reason experienced Sofware developers are paid higher salaries compared to many other jobs. In this article, I am going to share with you some tips on creating maintainable Java applications which will help you not just in the new year, but also in all the coming years in your software development career.  One aspect of development, which is often overlooked by developers is to create applications that are both easy to maintain and support. Since software spends 90% of its lifetime in maintenance mode, it's very important that your application is easy to configure, support, and maintain. 

Why Static Code Analysis is Important? Pros and Cons

In the last few years, Software code quality and security have gone from being a “nice to have” to a necessity, and many organizations, including investment banks, are making it mandatory to pass static code analysis tests, penetration testing, and security testing before you deploy your code in production. Static analysis tools like findbugs and fortify are getting popular every passing day and more and more companies are making fortify scan mandatory for all new development.  For those unaware of what static code analysis is, static code analysis is about analyzing your source code without executing them to find potential vulnerabilities, bugs, and security threats.

Top 23 Design Patterns Experienced Java Programmers Should Learn

Hello guys, if you want to learn Design Patterns and looking for a comprehensive tutorial which covers all important object oriented design pattern then you have come to the right place. Earlier, I have shared best Design pattern courses and books for experienced developers and in this article, I will introduce you with 23 common object oriented design patterns for writing better code. Design Patterns are tried and tested way of solving a problem within a given context. They are not invented, rather they are discovered, which is also obvious by use of word pattern. By using design pattern, you take knowledge of all wide communities and can safely use it to solve that problem. At times they might not give you perfect solution, require bit of tweaking, but they certainly provides one of the best solution, as long as you use them properly. While doing object oriented development, they are numerous task which appears quite often e.g. creating objects, structuring code, and implementing different behaviors based on different context.

Top 5 Cloud Computing Platforms Java Programmers Should Know

Cloud computing is Hot, it's the biggest IT trend of the last few years and will continue to grow strong in the coming future.

Top 10 Most Popular Programming Languages of the Last 50 Years and their Inventors

There are many programming languages out there in the software world, and they are still coming like Scala, Go, TypeScript, Rust, etc., but only a handful of them have managed to survive to date.

Programmers and developers, who those programming languages are icons of the programming world and sometimes I feel sad when a guy using a programming language doesn't know, who is behind that.

Top 10 Excuses Programmers Gives to Avoid Unit Testing

Though everyone loves unit tests and everyone agrees with the benefits they bring in, when the time comes to write them, you will see a lot of excuses, even from some of the more experienced and senior developers. At the heart of the problem of not writing unit tests or enough unit tests are two things, first is time pressure i.e. you don't have enough time to complete coding forget about writing unit tests. This problem comes due to erroneous estimation i.e. only estimating time for coding and not including unit testing as part of development.
