Process of Data Analytics

Data requirement: The first step in the data analytics process is to decide what type of data you need for your analysis and then proceed to gather them.

Data collection:  Once you are convinced of your requirement, you have to look for the sources to avail the data. There are various sources like questionnaires, case studies, direct observation, surveys, etc.

Data cleaning: Before sending the data for analysis, it is important to sort out the necessary data. This will clean up duplicate records or data having any kind of error. This is a mandatory step in organizing useful data.

Data analysis:  A number of tools and software for data analysis are available in the market to help you process or analyze the relevant information. Some examples of such tools are – Rapid Miner, Chartio, Redash, Metabase, Excel, R, Looker, etc.

Data interpretation: Once the data are processed using the mentioned tools, it is time to interpret the result and move towards making the most solvent decision using that.

Data visualization: Next is the time for presenting the insights graphically so that it is understandable for everyone. It helps people to read the datasets and compare the results with others. Some popular methods of visualization are – graphs, charts, pie charts, maps, bullet points, etc.

What is Data Mining?

Data Mining, also referred to as Knowledge Discovery in Data (KDD) is the process of sorting valuable data from vast data sets. With the help of advanced analytics tools and techniques, help businesses predict future patterns and make the most suitable decisions.

Data mining is an important part of Data Science that uses advanced Data Analytics techniques to transform valuable information into creating business planning and strategy. The information it gathers can also be used in Business Intelligence (BI).

In this way, Data Mining not only scrutinizes the historical data but also examines the currently streaming data. Effective Data Mining supports planning business strategies and implementing them. Beginning with marketing, sales, customer support, advertising, manufacturing, etc, Data Mining aids in operating finance and HR.

Even critical cases like fraud detention, security breaches, and risk management, etc are also benefitted by Data Mining. In this way, Data Mining affects not only business but healthcare, government, sports, etc.

Data Mining techniques basically work on two different levels. On one hand, it describes the target dataset. On the other, it predicts the consequences using a machine learning algorithm. In these ways, it surfaces the most important information, filters, and organizes them to create valuable results.

The task of a data scientist is to identify outliers through regression and classification methods. He or she is responsible for extracting necessary information, and collecting and visualizing data for concrete decision-making of the institution.

Types of Data That Are to Be Mined:

  • Stored data in a database: This is also called a database management system (DBMS). Every data stored in the database is related. Software programs manage these data and help to access them hassle-free. These data are mainly of three types, e.g., shared, distributed, and concurrent data. All these data are stored securely by the software programs.
  • Data warehouse: This is a single data storage that gathers data from different sources. The collected data then go through the process of cleaning, integration, loading, and refreshing. After that, the data are stored in a unified plan.
  • Transactional data: Every single online transaction has a unique ID. For example, flight booking, online shopping, and even a click on a website – all these transactions are stored in the database and help in the data mining process.
  • Others: There are many other varieties of data, like engineering data, multimedia data, data streams, spatial data, etc.

Process of Data Mining

The complete process of data mining follows the below-mentioned four steps-

  • Setting of business objectives: This is the foundation of the whole data mining process and is considered the most important one. Business stakeholders should work with the data mining expert to chalk out the main motives and achievable goals of the business. For the data scientist, this can be the hardest part demanding extra time and research to understand the business objectives. After the research, the target should be set by the expert and the same must be sanctioned by the company.
  • Preparation of data: Once the goal is marked then it becomes easier to chalk out the plan of data mining. The data scientist will then identify the particular information that will be able to answer the pertinent question to the business. These relevant data are then sorted and cleaned. In this step, all types of noises- e.g., missing values, outliers, and duplicates are removed. If the sorted data contains too many dimensions, then it is again calculated and cut down to only useful predictors, otherwise, too many dimensions may slow down the process of achieving accuracy.
  • Model building and pattern mining: Depending on the nature of the collected data, they are modeled with data relationships, such as correlation, sequential pattern, etc. A deep Learning Algorithm may be implemented in this step.
  • Evaluation and implementation: The finalized data become ready to be evaluated. If the result meets with the desired output, the dataset is used as a dependable predictor to guide the business with the best knowledge and plan for the future.

Data Analytics Vs Data Mining- the Key Differences Explained

 

1 Types:

Data analytics is of four distinct types, they are-

  • Descriptive analytics: This uses historical data and uses simple mathematical tools like spreadsheets.
  • Predictive analytics: This uses statistical analysis along with Artificial Intelligence to identify possible results.
  • Diagnostic analytics: Using machine learning, this digs into historical data to understand patterns and correlations (if any) of data.
  • Prescriptive analytics: This uses machine learning and artificial intelligence to help businesses in ultimate business-making. This is the most complex type of data analytics.

The main types of Data mining are-

  • Pictorial data mining: This transforms collected heterogeneous data into pictorial presentation. It helps in power plant monitoring, flight control, etc.
  • Text mining: This extracts high-quality data from different written texts through a computer. Through statistical pattern learning, data is derived from written texts such as websites, reviews, books, etc.
  • Social media mining: More often than not, this data mining is used in traditional or digital marketing. Valuable data is derived from user-generated content in social media and mobile applications to understand and categorize the user.
  • Web mining: in this process, useful data is automatically derived from web searches and restored from the World Wide Web. The result is used in e-commerce, content analysis, health care services, etc.
  • Audio and video mining: Multimedia or audio-visual is very accessible nowadays. From this video, huge data sets are extracted and then applied in the fields of security, entertainment, education, and medicine.

3 Method:

Let us now highlight the different methods in both data analytics vs data mining-

Some of the most used methods for data analytics are-

  • Cluster Analytics- This is the process of finding objects of similar groups to form clusters. This algorithm is based on machine- learning and works on unlabelled data. Clustering can be done in different ways, such as – density-based, constraint-based, distribution-based, centroid-based, etc
  • Cohort Analysis- This is behavioral analytics that categorizes data in a data set into cohorts or groups that share the same traits or behavior. By analyzing, the cohorts can understand well about their attitudes and choices.
  • Regression Analysis- This method is used to realize the relationship between two or more variables. The result is presented in a graph through independent and dependent variables.
  • Segmentation Analysis- In this method, users or products are divided into different groups to deliver customized advertising, brand positioning, etc.
  • Time series Analysis- This method is useful for non-stationary data, that is, data that fluctuates over time. Industries like retail and finance make use of this method.


Data Mining methods are-

  • Association: In this method of data mining, the co-occurrence of associated items is found in a collection. For example, when a shopper puts different items in a basket, it is possible to recommend some other associated items.
  • Classification: Through classification, we assign a class label to each item in a dataset. Classification is of two types- binary classification and multi-class classification.
  • Clustering Analysis: It is the process of grouping similar objects into one cluster. For, at first, the partition of data is made and then the label of the group is assigned according to their distinguishing features.
  • Prediction: By processing input datasets, the numerical output is generated through an algorithm. Unlike classification, this numerical output does not contain any label.
  • Decision trees: This structure contains root nodes, branches, and leaf nodes. The internal node denotes tests, the branch denotes the outcome of the test, and the leaf node denotes a class label.

 

4 Subject-matter expertise:
