Database Integration Testing – The Secret Recipe

June 6, 2022

Let’s talk about testing… Not about the importance of testing in general, but rather about automated tests against NoSQL Databases. The simplicity of writing and orchestrating them in build pipelines, and the power they unveil – high confidence in reliable code after making changes and before writing new code (TDD). Why test against an actual…

Multi-tenant database in NoSQL

August 31, 2021

How multi-tenant database can be arranged in NoSQL in general and in RavenDB in particular. For SaaS applications, multi-tenancy might seem like a simple problem at first glance. But just scratch the surface and it reveals itself as one of those topics where technical architecture concerns, business needs, security risks and user experience…

Entity Relationships in NoSQL (one-to-many, many-to-many)

January 4, 2021

We know how to maintain a relationship between two tables in SQL. Normalise. Add a reference field with a foreign key. When querying data from both tables – JOIN the two. It makes writing normalised records to the DB straightforward and optimises storage space, but it comes with a higher cost of querying the data. All the JOINs and GROUP BYs on…

Dynamic Fields for Indexing

The power of dynamic fields for indexing dictionaries and nested collections in RavenDB Yet Another Bug Tracker (YABT) we are building in this series needs to be flexible and accommodate custom fields and structures that can be added by the end-user. The custom fields is a widely-adopted concept in bug-trackers to manage additional fields on…

Hidden side of document IDs in RavenDB

November 13, 2020

At first glance, you don’t need to pay special attention to document IDs in RavenDB. The default autogenerated semantic IDs (e.g. users/1-A) are good enough – robust, concise, human-readable, customisable. Of course, there are other options including GUID if you want to go fancy, but the YABT (“Yet Another Bug Tracker”) sticks to the defaults and…

NoSQL Data Model Through the DDD Prism

September 29, 2020

The Yet Another Bug Tracker (YABT) we’re building in this series is a simplified version of a bug-tracking tool that implements some basic functionality. In spite of its simplicity, we leverage the Domain-driven Design (DDD) to describe independent problem areas as Bounded Context, emphasize a common language (Ubiquitous Language) to talk about…

Building an enterprise application with the .NET Core and RavenDB NoSQL database

September 28, 2020

NoSQL is not hard, it’s different. And to show that, RavenDB and I kick off a new series of articles dedicated to building enterprise applications leveraging the .NET Core + RavenDB bundle. We want to give as much of practical knowledge as possible, so let’s build a real-ish enterprise solution and explain various interesting aspects in the…
