  • So you’ve been using the NuoDB database for a while now, and you love it! You heard that NuoDB came out with a new release that includes a bunch of new features and functionality.

  • In SQL you can perform a lot of DDL operations, such as creating or renaming tables, creating or removing columns, and more, and these DDL statements are most often used when creating or upgrading your application schema.

    In a blog post earlier this year I outlined how to deploy the NuoDB database in Docker containers . To follow up on that, let's put NuoDB to the test. Your mileage will vary based on the available compute and disk storage used, but our

  • While many enterprises are now ready to embrace cloud computing, they’ve struggled to move highly transactional systems of record to the cloud. For enterprises in regulated sectors such as banking and other financial services, there’s been a real challenge as they look for ways to move mission-critical OLTP SQL databases — and the applications that rely on them — to the cloud. Historically, relational SQL databases required single-server architectures, which made scaling

  • Apache Zeppelin is a completely open web-based notebook that enables interactive data analytics, data ingestion, data exploration, visualisation, sharing, and collaboration.

    This project will demonstrate how to run analytic queries and data visualisation against NuoDB using Zeppelin Notebooks with SparkSQL, Python, and NuoSQL.

    We will also set up basic authentication using Apache Shiro to control access to the notebooks that you create.

  • The Financial Services industry is in the midst of widespread disruption as they experience both phenomenal growth and unprecedented competition.

    This tutorial will walk you through the whole process of using free Let’s Encrypt certificates in NuoDB. First, we will create certificates using Let’s Encrypt as described in their documentation. Second, we will convert those certificates into various certificate formats that NuoDB processes require. At the end of this tutorial, we will show you what to look for in NuoDB log files and how to use TLS in the various TLS enabled database drivers.

  • For those of you who aren’t familiar with it, NuoDB Community Edition (CE) is our free developer version of the NuoDB product. It’s for those looking to do research, deploy a database with a small project, or simply get started developing with our technology.
