Data science is scientific research which paves the way for a project-, program- or portfolio-centric analysis.
In Data mining, the identified trends and patterns are used by organizations to formulate operations, marketing and financial strategies to fuel business growth.
In Data Science, from the point where data gets collected. It is a broader field which includes data mining
In Data Mining, once data sets are created. It is a subset of data science
But to get a clear understanding of the two, it is essential to understand what each term represents, along with its workings and tools. As is obvious from the above, Data Mining is one of the many processes of data science.
Understanding Data Science
Data Science is a domain of study incorporating behavioural science, statistics, data mining, mathematics, information analytics, and predictive analyses. It is a wider area of research which makes use of many algorithms and operations to derive informative insights from both structured and unstructured information.
Gaining information from unstructured data is not possible through the traditional processes of Data Extraction – this is how Data Science becomes an integral domain in itself. The procedure consists of accumulating data, comprehending it, and using this understanding to arrive at an analysis. It is thanks to this process that data scientists can create various applications and products which deal with, and are created on the basis of data.
The Importance of Data Science
The organizational and social imprint of Data Science is diverse and wide. An MIT paper shows that businesses using gathered data to arrive at decisions and strategies are 6% more successful than their competitors. It is no wonder that data-driven decisions are becoming a favourite for every smart and tech-driven business out there. Data Science is rapidly changing the world perception of marketing tactics, consumer affinity, business issues, supply chain, corporate connections, and predictive modelling.
Dresner’s research discovered that industries helming the spike in huge data investment were Healthcare (64% adoption), Finance (71% adoption), Advertising (77% adoption), Insurance (83% adoption), and Telecommunications (with a whopping 95% adoption). Data Science may be a widespread field, but its core aim is to obtain data to arrive at well-researched decisions.
How does Data Science work?
Data Science comprises the following steps:
- Accumulating the data: The procedure begins with the accumulation of data – this data may or may not have structure, and it may even be semi-structured.
- Wrangling the data: The next step is to work upon the data. The data obtained is cleaned and converted to a comprehensible format to gain maximum output from it. Data wrangling is quite a lengthy task. Almost 80% of the work period is spent on this step of the procedure.
- Analyzing the data: Post wrangling, it is time for analysis. Statistic models and algorithms are used for analyzing the converted data.
