Feed: Radar. Author: Mac Slocum. Both quantitatively and qualitatively, the Radar team has uncovered a growing wave of change in software development and architectural trends. Organizations are increasingly choosing the combination of cloud, containers, and orchestration to implement microservices as their directional architecture. The need to support business processes and customer expectations—and to have flexibility, adaptability, and scaling for new projects and for migrating legacy systems—has organizations embracing the interrelated technologies and approaches we call Next Architecture. In this report, we cover background, technology and business drivers, and key components that define the Next Architecture concept. Every company has a ... Read More

Feed: Neo4j Graph Database Platform. Author: Jocelyn Hoppa. Like a complex system grid or an air-traffic-control map, a graph database is represented as a network of nodes and connections called a labeled property graph. The nodes, which appear as circles or squares, represent entities such as people, products, companies or orders.In Neo4j, the connections between database nodes are called relationships, and those relationships are as important as the nodes they connect. Each relationship is directional and knows its beginning and ending node, and each node knows about all other nodes with which it has an inbound or outbound relationship – ... Read More

Feed: MemSQL Blog. Author: Floyd Smith. In this presentation, recorded shortly after MemSQL introduced MemSQL Pipelines, two MemSQL engineers describe MemSQL’s underlying architecture and how it matches up perfectly to Kafka, including in the areas of scalability and exactly-one updates. The discussion includes specific SQL commands used to interface MemSQL to Kafka, unleashing a great deal of processing power from both technologies. In the video, the MemSQL people go on to describe how to try this on your own laptop, with free-to-use MemSQL software. Introduction to MemSQL: Carl Sverre I want to start with a question. What is MemSQL? It’s ... Read More

Feed: Redis Labs. Author: Chris Cheung. Successful applications tend to become complex over time. A microservices architecture offers the ability to decompose your app into many loosely-coupled services organized around business capabilities, thereby alleviating some of the complexities. Of course, microservices are not a free lunch, but for most large, complex apps, they allow teams to deploy new features faster, scale more easily, and pick the best technology stacks. But what about distributed data? Each microservice is able to select the right database for the right job by employing a data model based on key-value, graph, hierarchical, JSON, streams, search, and ... Read More

Feed: CronJ. Author: Pavan Kalyan; Before diving deep in the comparison of SQL vs NoSQL databases, let us first know about both the types in brief. SQL or Structured Query Language is a programming language that is typically used to manage data in relational databases. Relational databases use tables to store data and then develop insights from that data by using common characteristics within the dataset. A relational database uses SQL to create both data and the schema for that data, which describes fields in columns. Every record in this is called a row. On the other side NoSQL, is ... Read More
