Choosing the right database is an important decision when building a modern application. Two popular choices are PostgreSQL and MongoDB. PostgreSQL is a powerful relational database that organizes data into tables and supports strong relationships, SQL, transactions, and data integrity. MongoDB is a NoSQL document database that stores data in flexible, JSON-like documents. So, which […]
If you are learning Kotlin for the first time, one of the first concepts you need to understand is variables and data types. Variables are used to store information in a Kotlin program, while data types define what kind of information a variable can contain. For example, an application may need to store: Kotlin provides […]
PostgreSQL is one of the most powerful open-source relational databases available today. While beginners often start with basic SQL operations such as SELECT, INSERT, UPDATE, and DELETE, PostgreSQL offers many advanced features that make it useful for modern applications. From JSONB and powerful indexing to transactions, full-text search, window functions, and advanced data types, PostgreSQL […]
If you’re learning backend development, you’ve probably heard of databases like MySQL, MongoDB, and PostgreSQL. But what exactly is PostgreSQL? PostgreSQL is a powerful, open-source relational database management system (RDBMS) used to store, organize, and retrieve structured data. It is widely used for web applications, enterprise software, analytics platforms, APIs, financial systems, and many other […]
Kotlin Multiplatform (KMP) is becoming an increasingly popular approach for building applications that target multiple platforms while allowing developers to share Kotlin code. However, understanding Kotlin Multiplatform architecture is important before starting a real-world KMP project. Unlike traditional single-platform Android development, a KMP project can contain code that is shared across platforms as well as […]
Cross-platform app development has become increasingly important for businesses that want to build applications for Android and iOS without maintaining completely separate codebases. Two technologies that often come up in this discussion are Kotlin Multiplatform (KMP) and Flutter. Both can help developers build applications for multiple platforms, but they take very different approaches. Kotlin Multiplatform […]
Modern application development often requires businesses to build applications for multiple platforms such as Android, iOS, web, and desktop. Traditionally, developers build each platform separately. Android applications may use Kotlin, while iOS applications are commonly built with Swift. This can result in duplicated business logic, repeated development work, and additional maintenance. Kotlin Multiplatform (KMP) provides […]
Modern Android applications rarely work completely offline. Most apps need to communicate with a backend server to retrieve or send data. For example, an application may need to: To communicate with REST APIs in Android applications, developers commonly use Retrofit. Retrofit is a type-safe HTTP client for Android and Kotlin that makes it easier to […]
Building user interfaces is one of the most important parts of Android app development. Traditionally, Android developers created interfaces using XML layout files and then connected those layouts to Kotlin or Java code. Today, Android developers have another powerful option: Jetpack Compose. Jetpack Compose is Android’s modern toolkit for building native user interfaces using Kotlin. […]
