Java Records: A WebFlux and Spring Data Example
When defining classes for a simple aggregation of values, Java developers have traditionally relied on constructors, accessors, equals(), hashCode() and toString(), an error-prone practice that has low value and shifts the focus away from modeling immutable data. Java records were introduced as a first preview in JDK 14 in order to simplify how we write data carrier classes. The second preview came in JDK 15 and the finalized feature arrived in JDK 16. A summary...
Build a Basic CRUD App with ASP.NET Core 3.0 and MongoDB
Document databases have become increasingly popular due to their speed and ability to store huge amounts of data or semi-structured data. MongoDB has emerged as a leader in the document database space and, as a consequence, it may be necessary for developers to learn how to interact with MongoDB from .NET applications. This post strips away all the arguments that obscure how document databases can easily serve as a datastore for .NET applications. The app...
Use MongoDB in Your C# ASP.NET Apps
MongoDB is a document database. Instead of storing data in tables and rows, you store documents in a structure very similar to objects in the memory of your application. The schema is flexible and dynamic. You don’t need to define all fields upfront. Some MongoDB tutorials define model classes in C# and show how to read from and write to the database with them. This post takes a different approach, which also demonstrates how flexible...
Build a CRUD API with Java and MongoDB
This tutorial leverages two technologies that are commonly used to build web services: MongoDB and Java (we’ll actually use Spring Boot). MongoDB is a NoSQL database, which is a generic term for any non-relational databases and differentiates them from relational databases. Relational databases, such as SQL, MySQL, Postgres, etc…, store data in large tables with well-defined structures. These structures are strong and tight and not easily changed or customized on a per-record basis (this structure...
How to Connect Angular and MongoDB to Build a Secure App
MongoDB is often the first suggestion when it comes time to select a NoSQL database. But what is a NoSQL database, and why would you want to use one in the first place? To answer this question, let’s step back and look at SQL databases and where they shine. SQL databases are a good choice if you have well-defined data that will not change much over time. They also allow you to define complex relationships...
Build a Reactive App with Spring Boot and MongoDB
Reactive apps allow you to scale better if you’re dealing with lots of streaming data. They’re non-blocking and tend to be more efficient because they’re not tying up processing while waiting for stuff to happen. Reactive systems embrace asynchronous I/O. The concept behind asynchronous I/O is straightforward: alleviate inefficient resource utilization by reclaiming resources that would otherwise be idle as they waited for I/O activity. Asynchronous I/O inverts the normal design of I/O processing: the...
Build a Single-Page App with Go and Vue
Single-Page Applications (SPAs) improve user experience by offering rich UI interactions, fast feedback, and the relief of knowing you don’t need to download and install a traditional application. Browsers are now operating systems and websites are apps. While a SPA isn’t always the answer, for apps that rely on snappy user interaction they are increasingly common. To the end user, a well-designed SPA feels like rainbows and unicorns. From the developer perspective, reality can often...
NoSQL Options for Java Developers, Part II
Last month, I wrote about NoSQL Options for Java Developers. I analyzed the data available from a variety of sources (Indeed jobs, GitHub stars, Stack Overflow tags) to pick the top five options: MongoDB, Redis, Cassandra, Neo4j, and PostgreSQL. After writing this article, I shared it with a few experts I know in the Java and NoSQL communities and asked them the following questions: Do you agree with my choices of the top 5 NoSQL...
NoSQL Options for Java Developers
The Java community is one I know and love, so even though a NoSQL database is rarely tied to a language I’m writing this article for you, Java developers around the world. In this article, I’ll show you several options for NoSQL databases. After exploring all the options, I’ll narrow the choices down to the top five based on Indeed Jobs, GitHub stars, and Stack Overflow tags. Then I’ll let you know if they’re supported...
