Today, software development teams have lots of options to choose from, when it comes to programming methodologies, patters, paradigms, etc. The mainstream approach is to treat backend side as a CRUD data store.
But gradually, as your software product starts becoming more sophisticated you might consider moving away from that model. One of the alternative views on a process of an application development that you can pay attention to is CQRS.
It’s difficult to overestimate the importance of continuous integration and continuous delivery in modern development practices.

But what if your forms consist of multiple sub-forms, many inputs depend on each other, their validation rules might dynamically change, etc.? While developing software for the insurance industry, where forms are the crucial part Scalified team has gained a great experience of implementing powerful forms and today we’ll share some experience of how to build really reactive forms with Angular and ngrx-forms.
Database migration is essential and integral process of every software development. From the very begging of application development the number of database migration scripts increases with every feature, which requires database change. This slows down the process of testing, deployment and application integration. All these issues can be effectively solved by automating the process of applying database migration scripts. Flyway is one of the most popular tools in this area. It has plenty of features but most importantly it provides database version control. In this article we are going to configure Flyway tool to automatically apply database migration scripts in a typical Java EE application running inside JBoss container.
