Study Notes
Key Components of Data Analytics
- Data analytics encompasses gathering, analyzing, and reporting performance information to users.
- Utilizing data to develop models enhances decision-making and adds value to decision-makers.
Difference Between Database and Data Warehouse
- A database is a structured collection of data that supports daily transactions.
- A data warehouse is a centralized repository for data analysis and reporting, drawing from multiple databases.
The 3V's of Big Data
- Volume: Refers to the vast amounts of data generated every second.
- Velocity: Describes the speed at which data is created and processed.
- Variety: Highlights the different formats and sources of data encountered.
Speed Component of Big Data
- The speed component is commonly referred to as "Velocity."
Example of Unstructured Data
- Unstructured data can include text documents, images, or social media posts that do not fit neatly into existing data structures.
Drivers of the Big Data Revolution
- Advances in technology, increased digital data generation, and the need for data-driven insights are driving the big data revolution.
Data Analytics Reporting
- Reporting involves presenting analytical information about a company’s performance and environment to stakeholders.
Modeling Component
- Building models to predict outcomes and trends is essential for effective decision-making in data analytics.
Continuous Variables
- Continuous data variables can take any number within a range, including fractions or decimals.
Technology for Statisticians
- Statistical software and programming languages, such as R or Python, are highlighted as essential tools for data analysis.
Understanding Patterns
- In data analytics, a pattern is recognized when consistent trends or relationships emerge within the data.
Data Analysis Process
- The process of analyzing data using mathematics, statistics, and computer science is known as Data Science or Data Analysis.
Distinct Data Variables
- A categorical variable only accepts discrete, separate values with no possible intermediate values in the range.
Continuous Variable Definition
- In data analytics, a continuous variable is numerically measurable and can take any value within a given interval.
Insight Generation in Data Analytics
- Insight generation is a critical part of data analytics, involving the identification of patterns and significant trends within datasets.
