Oracle to PostgreSQL – Binary Objects

July 2, 2020/5 Comments/in 2ndQuadrant, Kirk’s PlanetPostgreSQL /by Kirk Roybal

Binary Objects in PostgreSQL definitely have caveats, and don’t behave the way you might expect coming from an Oracle background. This article demystifies the Blob, gives some practical advice for dealing with them, and improves your philosophy.

How to use Neural Network Machine Learning model with 2UDA – PostgreSQL and Orange (Part 7)

June 25, 2020/0 Comments/in 2ndQuadrant, Seemab's PlanetPostgreSQL /by Semab Tariq

This article gives a step by step guide to utilizing Machine Learning capabilities with 2UDA. In this article, we will use examples of Animals to predict whether they are Mammals, Birds, Fish or Insects. Software versions We are going to use 2UDA version 11.6-1 to implement the Machine Learning model. This version 11.6-1 combines: PostgreSQL […]

June 25, 2020/0 Comments/in 2ndQuadrant, OmniDB, PostgreSQL, Sadeq's PlanetPostgreSQL /by Sadequl Hussain

OmniDB is an open-source, graphical database management tool developed by 2ndQuadrant, a world-leader in PostgreSQL technologies and services. OmniDB is a browser-based, universal client tool that can manage major database engines like PostgreSQL, MariaDB, MySQL, and Oracle. Other soon-to-be-supported engines include SQLite, Firebird, MS SQL Server, and IBM DB2. Like any excellent database client software, OmniDB […]

Oracle to PostgreSQL: Reasons to Migrate

June 23, 2020/8 Comments/in 2ndQuadrant, Kirk’s PlanetPostgreSQL, PostgreSQL /by Kirk Roybal

PostgreSQL has quite a few compelling advantages, some of which are not found in any other database management system. This article will outline the ones that are most interesting to the Oracle developer seeking to do a migration or investigate alternatives for new development. To prevent this article from becoming another list of PostgreSQL features, it […]

Local Persistent Volumes and PostgreSQL usage in Kubernetes

June 22, 2020/0 Comments/in 2ndQuadrant, Cloud Native /by Gabriele Bartolini

Can I use PostgreSQL in Kubernetes and expect to achieve performance results of the storage that are comparable to traditional installations on bare metal or VMs? In this article I go through the benchmarks we did in our own Private Cloud based on Kubernetes 1.17 to test the performance of local persistent volumes using OpenEBS […]

Oracle to PostgreSQL: Basic Architecture

June 17, 2020/1 Comment/in 2ndQuadrant, Kirk’s PlanetPostgreSQL, PostgreSQL /by Kirk Roybal

This article provides the Oracle database administrator with equivalent PostgreSQL architecture knowledge. The process is a bit loose, but it is sufficient to bootstrap the concepts that are transferable and identify the ones that are not.

Oracle to PostgreSQL: START WITH/CONNECT BY

June 8, 2020/1 Comment/in 2ndQuadrant, Kirk’s PlanetPostgreSQL, PostgreSQL /by Kirk Roybal

And now we arrive at the second article in our migration from Oracle to PostgreSQL series. This time we’ll be taking a look at the START WITH/CONNECT BY construct. In Oracle, START WITH/CONNECT BY is used to create a singly linked list structure starting at a given sentinel row. The linked list may take the form of a tree, and has no balancing […]
