#WorldInnovationDay Hack Information Pack

We are providing to each participant access to Oracle Cloud Infrastructure (OCI) for the hackathon. The following resources are to make you effective with OCI.

Oracle Cloud Infrastructure

From past hackathons, we noticed a trend of what technologies and services are being used by the winning teams. Here are the top resources with some additional references.

  • For a single platform to store JSON, Graph & Spatial, perform ML or deliver Low-Code Apps, use Autonomous Database (here)
  • For establishing infrastructure with your OS of choice, use OCI Compute (here)
  • For Jupyter notebooks and ML packages, use Data Science Cloud (here)
  • For quick self-service and data visualisation, use Analytics Cloud (here)
  • For making sure everything is secured, use Oracle Security (here)
  • For most things you need for #AppDev, use Oracle AppDev (here)
Live Labs

You will need to learn quickly. These hands-on workshops will help you learn more about the services available.

  • For those who are interested in a single platform to store data (here)
  • For those who want to #lowcode (here)
  • For adding Blockchain to your datasets (here)
  • For those who are interested in data science (here)
  • For ML on datasets in the database (here)
  • For data storytelling with data visualisation (here)
  • For building microservices applications (here)
Next Steps

There will be a series of workshops where we will be present on different OCI topics in the week leading up to the hackathon. Make sure you have these in your calendar so you don’t miss out.

And reach out on the #WorldInnovationDay Hack 2021 Slack workspace if you need anything from the team.

Adding OAuth to ORDS

Adding security over the APIs across multiple layers was something that we considered when putting this project together. This perspective was reinforced at the #DigitalDefence hackathon in Nov 2020. Check out what happened (here).

We focus on the score and event APIs exposed by Autonomous Data Warehouse.

Here we will focus on the different REST APIs exposing the data hosted by Autonomous Data Warehouse. We started off with HTTP Basic Authentication but quickly turned to using OAuth. Here we’ll explore more about the OAuth side and how to get that started.

Kiron – A #VisFSG Project

Over the past couple of weeks, there’s been another Viz for Social Good project that was running. For this project, the supporter was Kiron Open Higher Education (https://kiron.ngo/en/) – an organisation that is providing a learning platform for refugees and underserved communities in the Middle East.

The project was to put a spotlight on refugees and immigrants and was linked to the virtual refugee conference called Amplify Now (https://virtualrefugeeconference.com/). Submitted projects went into the running to be featured at the conference itself.

So what’s my take on this?

The tech behind the social good

Over the past couple of weeks, there’s been some work by a few of us to #GiveFirst. I’ll share a little context but will get to the tech very quicker.

From March 3rd (2020), an event called Viz for Social Good with Sunny Street (click “here” for the eventbrite for some of the details) was being run. This was a virtual datathon “a data visualisation hackathon” being hosted by Frederic Fery for a company called Sunny Street. Also with what’s happening, the pitch event had gone virtual. I’ll add comments to this post as well get closer or to reflect on the outcomes. The virtual event is live on March 19th on zoom (https://zoom.us/j/9065708856) at 5pm AEST (+10 GMT).

Connecting Jupyter Notebook to Oracle Autonomous Database

Jupyter Notebook is an open source web application for Machine Learning and Data Exploration.

In this post I will show you how to connect a Jupyter Notebook to Oracle Autonomous Database and explore the data using Python.

The assumption is we already have a Jupyter notebook sandbox running on Oracle Cloud compute instance.

Prerequisites:

Oracle Integration Cloud Autonomous Transaction Processing Adapter Configuration !!!

Oracle’s two major ground breaking innovation last year were Autonomous Data warehouse (ADW) and Autonomous Database Transaction processing (ATP) both are database offering suitable for different workload and are self-driving, self-securing, and self-repairing in nature. If you want to read more about these services then please go through above links.

ADW/ATP both can be quickly provisioned on Oracle Cloud Infrastructure, it’s take less than 5 minute to spin ADW/ATP instance and database is ready to connect.

User can use Oracle SQL Developer to connect to ADW/ATP database as long as they are supported version. These DBaaS services also offers out-of-box browser based SQL Developer tool which can be used to run any kind of SQL statements.

Here is sample snap of browser based SQL Developer capabilities –

Once user has Database ready, obviously there could be requirement to access data residing inside ADW/ATP instances.

Fortunately, Oracle Integration Cloud provide Adapter for connecting ADW/ATP instance, click here to know more about ATP Adapter capabilities –

In this blog I will be covering simple steps how you can connect to ADW/ATP instances using OIC Autonomous Transaction Processing Adapter (ATP) Adapter.

I made assumption that ADW/ATP instance already exists. if you not sure how to create ADW/ATP instance then refer this blog which was written by my colleague who already explained how to create ADW/ATP database instance and connect from SQL developer.

So, let move forward. Login to your Oracle Integration Cloud (OIC) home page >> Integration >> Connection >> Create >> search for “Oracle ATP” >> select the same

Why Would you Monitor an Autonomous Database?

You probably heard that Oracle Autonomous Database (ADB) leverages machine learning to automate with traditional infrastructure related database administration tasks such as security, backups and patching.

No matter how well designed your database infrastructure is, performance and issues relating application or external components which make up the application ecosystem can still have an impact on end user response time or availability.

Why we must cede to our robot overlords (to do the dull stuff)

Can I get a show of hands – whose spine shudders at the sound of their own phone ringing? If your hand is up, chances are a component of your role (or role in days gone by… the scarring can be permanent) involves operations. Day or night, it’s that dread associated with wondering “What now?”. A few years back, enterprise started outsourcing the problem of supporting key business systems to 3rd party services, and while this reduced the quantityof calls, it only served to increase the quality – now when the phone rings at 3am, you know things are bad. Real bad.

AUSOUG Connect 2018 – Talking Dev

ausoug-title-01.pngIn November 2018, I had the privilege to attend the Australian Oracle User Group national conference “#AUSOUG Connect” in Melbourne. My role was to have video interviews with as many of the speakers and exhibitors at the conference. Overall, 10 interviews over the course of the day, 90 mins of real footage, 34 short clips to share and plenty of hours reviewing and post-editing to capture the best parts.

Teaching How to Invoke REST APIs from Oracle Visual Builder Web/Mobile Apps

In this blog, I am going to show you how to build a nice and simple UI with data coming from invoking REST APIs. All without code, but in just a few clicks.

I consider myself a good backend developer, good at making things functional, but I really struggle every time I need to produce nice UIs. However, using Oracle Visual Builder, I feel like I don’t have to be a UI developer or designer, I can very easily produce nice and friendly mobile UIs that consume my backend REST APIs. If you are like me, a backend programmer who loves API-first design approach, I’m sure that you will find this blog not only informative, but also refreshing.

This is a quick view of what we are going to achieve in this article:

  1. First, we are going to auto-create Service controls in Oracle Visual Builder by pointing to existing REST APIs.
  2. Then, we are going to use the out-of-the box widgets and components to build a simple, yet powerful UI that consumes such APIs.
  3. Finally, we are going to publish the UI and test it across different media, e.g. Web on a laptop, mobile, tablets, etc.
