Leveraging ETL to Enable your Domain Driven Design

How much do you know about Domain-Driven Design (DDD)? It's a design approach to software development where the language and structure of software code match the business domain. The concept comes from a 2003 book by Eric Evans. And it influences software architects, information architects, data engineers, and computer science professionals who organize code and solve some seriously stressful software problems. Domain-Driven Design is a super-successful concept with brilliant business logic benefits.

Accelerating software projects using the feature design process

Every agile software engineering team wants to do these three things: The reality is that as we focus on improving one thing, sometimes it is at the expense of another. If we focus on accelerating feature development, feature quality could suffer. If we focus on improving feature quality, development could slow, potentially delaying the release. But what if we could have it all?

How to Design a Scalable Rate Limiting Algorithm

Rate limiting protects your APIs from inadvertent or malicious overuse by limiting how often each user can call the API. Without rate limiting, each user may make a request as often as they like, leading to “spikes” of requests that starve other consumers. Once enabled, rate limiting can only perform a fixed number of requests per second. A rate limiting algorithm helps automate the process. In the example chart, you can see how rate limiting blocks requests over time.

Testing for intuitive design

Apps are essentially technology products—products that aim to solve a problem for users. Design is a salient feature in all apps; it is how users understand, interact, and use a product. The less intuitive an app is in terms of design, the harder it is for its target audience to learn to use it. Poor design ultimately costs products their user-base. No one will return to an app that is hard to use, nor recommend an app that is difficult to understand and learn.
