Analytics In Healthcare Industry

In very simple words, the process of predicting the probability of an event using mathematical models is defined as predictive modelling. In different fields there has been a wide-spread application of predictive modelling. This is mainly for the purpose of decision making. Recently, the technological advancements have made it possible for predictive modelling to expands its reach within the healthcare sector.

Making right decisions at the right time is the success…

DATA WAREHOUSE GOVERNANCE

What is Information System Governance?

The objective of IT governance is to maximize the added value of IT to the company strategy in its definition as well as in its application. It means it leads the developments, the implementation and the use of IT. According to the governance experts it has to be pre-schedule, planned, transparent, fair and efficient. Thus it is important to:

Organize a governance structure (setting up of a department including stakeholder’s…

The assumptions on which the RDBMS is based has changed: the ideal data structure

We have been using tables in the relational database, mostly for the transactional purposes, and that proves effective. Considering the data size and analytic purpose, however, the data structure might need to be redesigned for better efficiency.

To determine how to decompose the complexity of big data, we have observed the way the organisms function. In the physical world, the universe is organized into a hierarchy of…

The Book: Big Data, NoSQL, Cloud A Paradigm Shift

It seems there are many books available and there are many on the topics of Big Data, NoSQL and Cloud, however for non-technical managers/executives, these sound Buzz Words. The book on this topic is now available at the given link: http://lnkd.in/b2xiuqy. This is a book for the readers, who want to explore the knowledge about Big Data, NoSQL (Not only Structured Query Language) and Cloud, which is a paradigm shift that we are witnessing…

The assumptions on which the RDBMS is based has changed: data and code

In general, computer scientists treats code and data in two very different ways. Virtual memory was originally developed to run big programs (code) in small memory, while data are entities kept in external storage and must be retrieved into memory before computing. As a result, today’s application developers think by instinct the programming model based on storage and explicit data retrieval. This model, referred to as storage-based computing, plays an important role and has done a great job…

Critical Data and the Organizational Construct

The term "critical thinking" is often found in job postings.  Some would argue that this essentially means, "Thinking outside the box."  Karl Marx, who asserted that labourers represent a class of people, has been described as a critical thinker.  Regardless of how a person feels about Marx, it goes without saying that the phenomena of social classes is well-established.  Politicians for instance fight for the support of the "middle class."  How precisely does such an observation by this…

Why the Business Gets Frustrated with IT: the Data Warehouse

Defining the Problem

I propose that business frustration with IT is generally not a communication problem.



I often see managers frustrated with IT, but seldom is the cause a breakdown of communications - as we like to tell ourselves. Good managers always demand clear concise communications. When pressed, IT people, as well as other departmental folks, are able to deliver this easily enough.

The chief…

10 signs that you are a data scientist

http://ficolabsblog.fico.com/2013/10/top-10-ways-you-know-youre-a-data-scientist.html

I'd add an 11th one as well: you check data science sites before you check news sites in the morning!

10. You think … “So much data, so littl…”

9. You know what heteroscedasticity is.

8. Your best pick-up lines all include the word “moneyball.”

7. You look at your grocery…

What is the difference between in-memory and in-place computing approach?

To be short, in-memory computing takes advantage of physical memory, which is expected to process data much faster than disk. In-place, on the other hand, fully utilizes the address space of 64bit architecture. Both are gifts from the modern computer science; both are essences of the BigObject. 

In-place computing only becomes possible upon the introduction of 64bit architecture, whose address space is big enough to hold the entire data set for most of cases we are dealing with today.…

Big Data and Education Data Mining

Big Data is big in nature, however Education data is not that big yet compared to Big Data. Quantitative analysis, Audio-Video recorded data of Education related research and general research work conducted by the academic institutions is steadily increasing. The data change is started within our education system as our students are taking exams, courses, conducting their research using computerized means. This means that the searching behaviors of students or whoever associated with…

Search for Embodiment in Data Mining

Above - During a Session at the Archives of Ontario in 2011

In this blog post, I describe my early experiences leading me to conclude, data as we know it tends to be "disembodied" - that is to say, often lacking any kind of connection to different types of bodies.  When we talk about things being disembodied, I suspect some form of decapitation is…

STEM Education and Big Data

STEM is an acronym for the fields of science, technology, engineering and math and it has a push within United States, however there is a big factor is not taken into consideration yet by the masses in the world of Education, and that is the best use of Big Data. This is a lacking factor, as we are still exploring Big Data and its utilization at a novice level by our selves. Education by itself is a huge and vast field to conduct the research, by have an exploration within the research…

Creating Complex Encoded Objects from Qualitative Data

I have always found the task of converting qualitative data into something quantifiable a bit challenging.  A common route might be as follows:  assemble all of the resources containing qualitative information (e.g. questionnaires containing open-ended questions); seek out apparent themes in the responses; and quantify how frequently these themes are mentioned or raised.  This methodology leaves open the question of when something is or isn't a theme, and whether something must be a theme in…

Reductive Versus Expansive Data

I have so far encountered two general types of data . . .

Reductive Data

This is data that conforms to prescribed criteria.  I sometimes describe it has the metrics of criteria or measurements of conformity.  For instance, an organization might want to measure something potentially obscure like "efficiency."  It therefore becomes necessary to establish under what conditions or criteria something is efficient.  I describe…
