It provides a convenient way to interact with databases using Java objects, making database operations more intuitive and less error-prone. One of the central components in JPA is the EntityManager. In this blog, we will delve into the EntityManager, understanding its role, […]


Introduction Git is a version control system used for tracking changes in computer files. It is generally used for source code management in software development. 1. The most basic building block of version control is a “repository”. Think of a repository as a kind of database where your VCS stores all the versions and metadata […]


A pipeline refers to a set of automated processes and tools that enable the continuous integration (CI) and continuous delivery (CD) of software applications. Jenkins pipeline can be defined using two different scripts- Declarative and Scripted. The Declarative Pipeline offers a simpler and more human-friendly approach by using a Domain-Specific Language (DSL) to define stages, […]

Association, Aggregation, and Composition in UML

Unified Modeling Language (UML) is a visual language used in software design. It’s just like preparing the design model before constructing the building. In UML, we use three key concepts to define how classes and objects relate to each other: association, aggregation, and composition. Example: Consider a “Teacher” class and a “Student” class. An association […]
