Definitions For The Four Types of Analytics 

To understand the importance of analytics to your organization, you must first understand the type of analytics themselves. 

Analytics are pivotal in decision-making and create valuable insights for organizations. Knowing the types of analytics and their value will help guide you in various aspects of your business and analytics journey.

The four types of analytics are:

Descriptive Analytics, Diagnostic Analytics, Predictive Analytics, and Prescriptive Analytics.

1. Descriptive Analytics

This type of analytics is used when assessing historical data to answer the fundamental question of “What happened?”. Looking at patterns of past events, we can identify specific patterns that are predicted to occur again within the data. 

Descriptive analytics is often visualized as Pie charts, bar charts, tables, or line graphs.

2. Diagnostic Analytics

A form of advanced analytics that examines data or content to answer the question, “Why did it happen?”. It is characterized by techniques such as drill-down, data discovery, data mining, and correlations this usually occurs after an organization has achieved descriptive analytics. 

3. Predictive Analytics

Another type of advanced analytics that uses data and information to answer the question “What is likely to happen?”. 

Predictive analytics is impactful for organizations that require large amounts of high-quality data. This technique involves forecasting, multivariate statistics, pattern matching, predictive modeling, and regression analysis.

4. Prescriptive Analytics

The final level and most advanced level of analytics is prescriptive analytics. This method analyzes analytics to determine “What should be done?”. 

These insights rely not only on the quality of your analytics but also the accuracy to ensure that organizations can make well-thought decisions to achieve desired results and to increase revenue.

Types of Data

Big Data

Refers to large amounts of data collected from various platforms in real-time that are analyzed. Big data uses components of AI through machine analyses to understand data and information to be most efficient.

Master Data

Foundational data is stored and centralized across all aspects of the business. Master data is used across multiple systems and processes of your business functions. This is the most common data linked to all other data sets within your organization.

Transactional Data / Event Data

This data type is utilized to record the transactions of the data across various functions. The data is forecasted to predict business events and the business transactions to follow and to record instances of change.

Transactional data is monitored and updated on an ongoing basis. This data can be categorized into product segments, customer segments, and price. 

Data Governance, Modeling, Quality, Strategy

Data Governance 

A set of practices including both monitoring and planning data to ensure it is useful as a strategic asset. The goal is to ensure confidence in the data for its use. 

Dimensional Modelling

The final step of structuring your data involves developing context to the data adding value and insights to the data user. Identifying and categorizing the data will then be presented in the form of tables. 

Data Quality 

The data is consistent and reliable to ensure accuracy in providing useful insights to the data consumer and is “fit for use.” 

Data Strategy

The set of decisions and actions that address how your organization will solve the critical pieces of data that support your business goals. 

 Some questions to ask when developing your data strategy include:

  • Am I spending my investment the right way?
  • Is this the proper technology we should be using?
People plus process plus technology plus data equals a strong data strategy.
