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…Continue

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…Continue

Data Analytics in Government
“If it ain’t broke don’t fix it.”
Were that remark directed at government at any level for any function the response would be predictable - could anything be more broke than government. Probably the f-uped conjunction would work its way into most responses. It’s hard to believe that anyone within or associated with government could react differently, even if their outward response were subdued.
Just experiment with it.…Continue

Database administration is complex, repetitive and time consuming. DBAs have to work long hours during off hours downtime. The outage of database costs heavily to the companies and affect their repute.
Shopping engines and online shopping places are highly dependent on database performance. Slower application…Continue

The purpose of this article is to demonstrate how the practical Data Scientist can implement a Locality Sensitive Hashing system from start to finish in order to drastically reduce the search time typically required in high dimensional spaces when finding similar items. Locality Sensitive Hashing accomplishes this efficiency by exponentially reducing the amount of data required for storage when collecting features for comparison between similar…Continue

Very interesting article published by the American Statistical Association. The picture below compares computer science with statistical science - before (I guess the early nineties) versus now. The column labeled CS3 (CS for Computer Science) represents modern computer science, actually this is data science. What's left in statistics is for the reader to guess, I suppose.…Continue

The prime benefit of data warehousing is simplicity. The presentation of data in data warehousing is a single image. This single image is made by collecting data from different department of the organisation. Due to this, time for production and operation of data reduces and thus simplifies the decision making as well. This reduction of time to access data also leads to increase in production and effectiveness. Data warehouse will also help to enhance the function of operational systems. It…Continue

I tend to examine the different roles played by data. For instance, when I work on computer code, I often ask myself what the presence of data is meant to accomplish. Sometimes the analysis is not at all straightforward or simple. In society and organizations, people exist and persist in the records as data. The data survives even as employees come and go. I therefore consider it important to regard the data and its environment as a system in itself, something that has a life all of its own.…Continue
