Definition of Terms

 

Definitions: Data Analytics | Data Science | Business Analytics | Artificial Intelligence | Machine Learning

 

Data Analytics

Data Analytics is defined as qualitative and quantitative techniques and processes used to improve productivity and business performance. Data is extracted in order to identify and analyze specific data and patterns through various techniques required by organizations. Data analytics is widely used in business-to-consumer (B2C) applications. Organizations collect and analyze data associated with customers, business processes, market economics or practical experience. Data is categorized, stored and analyzed to identify purchasing trends and patterns.

 

Data Science

Data Science is a broad field comprised of the collective processes, theories, concepts, tools and technologies that facilitate the review, analysis, and extraction of valuable knowledge and hidden information from raw data. Data science enables the use of theoretical, mathematical, computational, and other methods to review, evaluate, and model data. Its purpose is to help individuals and organizations make informed decisions from stored, consumed, and managed data.

 

Business Analytics

Organizations employ methods and techniques called Business Analytics (BA) to measure performance. The field of business analytics is composed of statistical methods that can be applied to specific projects, processes, or products. Business analytics is extremely useful in identifying weaknesses in existing processes and highlighting meaningful data that can prep organizations for future growth and challenges. Business analytics is largely employed in decision support systems, continuous improvement programs, and elsewhere to help organizations remain competitive.

 

Artificial Intelligence

Artificial Intelligence (AI), also referred to as machine intelligence, is a branch of computer science that aims to infuse software with the ability to analyze its environment using either predetermined rules and search algorithms or pattern recognizing machine learning models, and then enable it to make decisions based on those analyses. In this fashion, AI attempts to mimic biological intelligence to allow the software application or system to act with varying degrees of autonomy, thereby reducing the need for human intervention for a wide range of functions.

 

Machine Learning

Machine Learning (ML) is an area of artificial intelligence that is focused on the technological development of human knowledge. Machine learning enables computers to handle new situations through analysis, self-training, observation, and experience.
