Feed: MemSQL Blog. Author: Rick Negrin. There is a trend in industry which says that modern applications need to be built on top of one or more special-purpose databases. That every application benefits from using the best-of-breed technology for each requirement. And that the plethora of special-purpose options available from certain cloud providers is reasonable to manage. That’s all BUNK. The reality is that navigating the choices, figuring out how to use them effectively, and dealing with the ETL and inevitable data sprawl, is so difficult that the pain far outweighs any technical advantage you might get. In the vast ... Read More

Feed: Cambridge Intelligence. Author: Andrew Disney. Colors can make or break your data visualization.A carefully selected color palette helps you to harness the pre-attentive processing powers of the human brain, and makes insight clearer and easier to find. A badly chosen color palette obscures the information your users need to understand, and makes your data visualization less effective and harder to use.This blog post explores some data visualization examples, basic color theory, and explains how it can help you design visualizations that look good, and make data more compelling.Let’s start with some examples to show you the importance of choosing ...

In this final post in our three-parter exploring the typical challenges you face when visualizing your graph data for the first time, we look at the ‘starburst’ – a pattern where one heavily connected node dominates the chart.Usual suspect #3: it’s hard to see past a starburstWhere do starbursts come from?In previous posts, we saw how the underlying data source plays a significant role in determining whether you see a chart dominated by snowstorms or hairballs. But in both those cases, the main focus was on visualizing a dataset in its entirety.When working with ... Read More

Feed: Neo4j Graph Database Platform. Author: David Penick. “Even something as simple as mapping your IT network, which really makes sense when you look at it as a graph, takes the concept of graph and makes it a little bit more tangible,” said Jennifer Reif, Developer Relations Engineer at Neo4j.A graph database like Neo4j is different from what most developers have worked with before. It requires a new perspective and thinking outside the box, but builds on what they already know.In this week’s five-minute interview (conducted at GraphTour DC 2019), Jennifer Reif shares her excitement about spurring aha moments and ...

(As organizations look to modernize their applications, many are turning to a microservices architecture to deconstruct their legacy apps into collections of loosely coupled services. This profound change inspired us to reach out to Redis Labs customers in various stages of this journey to microservice architectures. We will be telling their microservices stories in a series of blog posts in the coming weeks.)When Mutualink looked to modernize its Interoperable Response and Preparedness Platform (IRAPP), the company’s IT team turned to a microservices architecture to enable dozens of technology components to work seamlessly together. That’s ... Read More

Feed: Redis Labs. Author: Sheryl Sage. The data layer is one of the first things to consider when moving to a microservices architecture. That’s because in a microservices architecture, each service manages its own data and is responsible for its own private data store. Understanding the role of the database in each service is critical. Depending on the service, for example, database could be the single source of truth, a temporary store, or something in between. Kyle DavisLoris CroThat’s one of the most important concepts in our new free e-book: Redis Microservices for Dummies.

If you want to uncover the most influential, well-connected or important individuals in a network, you should turn to social network analysis centrality measures. These graph analysis algorithms are designed to unpick complex networks and reveal the patterns buried in the connections between nodes.In this blog post, we’ll take a look at two centrality measures in our graph visualization toolkits: EigenCentrality and PageRank.How do they work? When should you use them? Read on to find out.EigenCentrality: understand network influenceEigenCentrality measures a node’s influence. It starts by measuring each nodes ‘degree’ score – which is ...
