The history of advanced analytics is rooted in the evolution of data analysis and computing technology, which has progressed significantly over several decades.
In the early 20th century, data analysis was primarily manual, involving basic statistical methods and simple calculations. The advent of computers in the mid-20th century revolutionized data processing, allowing for more complex analyses. During the 1960s and 1970s, the development of databases and data management systems laid the groundwork for storing and retrieving large volumes of data efficiently.
The 1980s and 1990s saw the rise of BI tools, which enabled organizations to generate reports and conduct descriptive analysis. These tools provided insights based on historical data but were limited in their predictive capabilities. Concurrently, advancements in statistical software and methodologies emerged, paving the way for more sophisticated data analysis techniques.
The late 1990s and early 2000s marked the beginning of the big data era, driven by the exponential growth of data from the internet, social media and sensor technologies. This period saw the development of more advanced analytics tools and techniques, such as data mining, ML and predictive and prescriptive analytics. The advent of open source programming languages like R and Python further democratized access to advanced analytical methods.
In recent years, advancements in AI and ML have propelled advanced analytics to new heights. Cloud computing has made it easier to store and process vast amounts of data points. While AI algorithms can analyze data with unprecedented speed and accuracy, and generative AI is an emerging tool in the field.
Advanced analytics and traditional business analytics differ in several key aspects, primarily in terms of their complexity, techniques and outcomes.
Traditional analysis focused on descriptive analytics, answering questions like "What happened?" and "Why did it happen?" It involved summarizing historical data through basic statistical measures, reporting and visualization techniques. Advanced analytics goes beyond describing past events to predict future outcomes and prescribe actions. It includes predictive and prescriptive analytics, answering questions like "What will happen?" and "What should we do about it?"
Simpler tools and techniques such as SQL queries, basic data aggregation and visualization tools like Excel or standard BI dashboards characterize traditional analytics. Advanced analytics employs sophisticated methods like AI, ML, data mining, natural language processing (NLP) and simulation. It often uses advanced programming languages (for example, Python, R) and specialized software.
Traditional methods that are dealt with structured data from internal databases and used relatively small to moderate data sets. Advanced analytics can handle large volumes of structured, semi-structured and unstructured data from diverse data sources, including big data from social media, IoT devices and cloud platforms.
Traditional analytics provided insights into past performance and helped in understanding historical patterns. It was useful for generating standard reports and dashboards. Advanced analytics delivers deeper, with predictive modeling, real-time decision-making and scenario analysis. It helps in optimizing business operations, identifying new opportunities for business value and mitigating risks.
Advanced analytics encompasses various sophisticated techniques. Some of the key techniques involved include:
Predictive analytics: This technique uses historical data, statistical algorithms and ML to predict future outcomes. It helps organizations forecast trends, identify risks and seize opportunities.
Statistical analysis: This technique uses statistical methods to collect, review and interpret data. It includes hypothesis testing, regression analysis and variance analysis to identify relationships and trends within data.
Text analytics: Text analytics, or text mining, extracts useful information from unstructured text data through NLP, sentiment analysis and text classification.
Big data analytics: This technique handles and analyzes large, diverse data sets (structured, semi-structured and unstructured) using technologies such as Hadoop, Spark and NoSQL databases.
Cluster analysis: This is a technique whereby cluster algorithms are used in advanced analytics and data mining to group a set of objects or data points into clusters or groups.
Advanced analytics relies on a range of sophisticated technologies to process and analyze complex data sets. Some of the key technologies that are used include:
