Keynote@ER 2019 - The Role and Challenges of Data in the Digitalization Era - By Veda Storey


The Role and Challenges of Data in the Digitalization Era

Prof. Veda C. Storey



Whenever she asks her students to talk about Data, they respond: "it is everywhere"
Real-time data
Integrity
Inferencing
Prediction
----
Overview
1) A Digital World
2) Data Management 
3) Problems and Applications
She has been working on this with Carson Woo, so he gets credits too. 
----
Closed vs. Open Environment
Closed - data generated, collected and used within organizational boundaries.
Open - users have access to sources of data that are open and shared (e.g. web)
----
Progression of Data Management
  1. Structured Databases
  2. Big Data
  3. Digitalization - Continuous Innovation based on Data (we are moving here)
----

1. Data Challenges
  • Sheer Volume, 
  • Discover and interprete patterns in data, 
  • Technological advances (e.g. blockchain)

Traditional Data Management Challenges (we find these in the textbooks)
  • Syntax
  • Structure
  • Semantics
  • Situation (Context)
----

2. Big Data 

  • Creative capture and application of data.
  • There are many ways we can capture, organize and share data.

Big Data Challenges 
  • Volume is difficult to control
  • Variety
  • Velocity
  • Veracity
  • Value is difficult to assertain (in a model, Value is in the middle of the other 4 V-words)

she gave a few examples of different volumes of data - until petabytes (amount of photos on facebook). Interesting example: Wallmart - 40 petabytes of recent transaction data. This data can be modeled, maniputlated and visualized. 

----

Puting together the Ss from traditional data management and the Vs of Big Data. 
Open challenge: how to account for all Vs and Ss in an integrated manner?
----
Digitalization
Definition: conversion of analog to digital information and processes recognizes transformative role of technology as it digitizes many different aspects of processes and operations across business and society
Impact: increasing pace of digitalization means that as a society, we are changing the ways that things are done, and we must adapt.
----
What are the data challenges of Digitalization?
She presented a 3D framework, showing three axis (x, y and z) with the Ss on y; Close and Open environment in x; and people, task, structure and technology on z. 
*Where did the Vs go? They are important as well! 
----
Emerging Technology: Blockchain
In a model of Higher Education, traditionally, Universities hire professors and students pay Universities. In a blockchain model, you may take out the MiddleMan, i.e. the University. There will be some kind of smart contract: as soon as the students fulfil the requirements for their degree, they will graduate.
----
They looked at the four Ss in light of Blockchain 
Another 3D model, but with a cone on the x-axis. 
*Strange... I do not understand why we should be worried specifically with Blockchain. I mean, there are several emerging technologies. Why does this one merit attention? She did not motivate very well this point.
----
Applications - How can data help?
- Feeding 10 billion people
- Healthcare Monitoring
