Data Warehouse Architecture

According to Weisensee et al., Data warehouse architecture follows following principles:

  • Data Sources
  • Data Warehouses
  • Data Marts
  • Publication Services

Extraction, Transformation and Loading (ETL):

ETL process is the foundation of BI. Success and failure of BI projects depends upon ETL process. It plays a vital role to integrate and enhance the worth of data. After the extraction, cleansing and arrangement…

Proposal for a new type of scoring system

In digital analytics, scoring Internet traffic is used to detect click fraud, and to find types of search keywords that convert well (to a sale). Quite often (for large ad networks) conversion data is poor or challenging: some clicks have a 0.2% conversion rate, some have a 30% - depending on the type of website, price, product, conversion type and other factors (even hour of the day has an impact).…

Starting down the path of Data Science

I've always been interested in data, how it's interpretted and the different ways it can be sliced. However, I've always considered statstics itself to be a math that I didn't like. As "data science" and "big data" became more popular, however, I started to look into ways to learn more about it and possibly use it as a entry into another act of my career.

The advent of MOOCs has opened up the possibility of learning new subjects and subject-focused websites like Data Science Central…

My data science journey

I describe here the projects that I worked on, as well as career progress, starting 25 years ago as a PhD student in statistics, until today, and the transformation from statistician to data scientist that occurred slowly and started more than 20 years ago. This also illustrates many applications of data science, most are still active.

Early years

My interest…

R as Ad Hoc

I was reading through my Twitter feed the other day and saw a comment about the R language being too ad hoc for users.  It got me thinking, "Is that bad? Aren't most languages initially seen as ad hoc?".  

The beauty of R as a data science tool is its "ad hocedness" in that its use can satisfy multiple interests.  Initially I can see this as troublesome in that learning the specificity of a tool's use can be daunting.  But in the long-run I think this benefits a…

Business Intelligence Architecture

According to the Asghar et al. (2009), Business Intelligence (BI) is divided into two main parts: (a) BI dimension and (b) BI process. Knowledge, functionality, technology, business and organisation are categorised under BI dimension. The performance of data sources, data warehousing, ETL, OLAPS and other related tools are categorised under BI process. Basically, dimensions and processes are interrelated to form a complete life cycle of BI system…

Addition of Different Dimensions to Data

I was often the lone wolf among my peers in university because I supported a prominent place in society for corporations and an important social role for capital. I questioned whether the directors and executives of companies entered into boardrooms really intending to “oppress” people such as minorities and people with disabilities. Did they deliberately make bathrooms inaccessible to people in wheelchairs perhaps to advance their preconceptions of who gets to go to the bathroom, I pondered…
