There are several data science Python libraries available as of now. While some of them are already popular, others are improving inch-by-inch to reach the acceptance levels of their peers.

Big data analysis and data analysis are different and connected. The focus here is on the differences and connections between the two in terms of technical requirements, usage scenarios, and business scope.

Data analysis is divided into different types, including data analysis perspective, business perspective, implementability perspective, market perspective, and so on.

Our commonly used data analysis methods include cluster analysis, factor analysis, correlation analysis, correspondence analysis, regression analysis, and analysis of variance.

Data Analysis refers to the process of analyzing collected data with statistical analysis methods, extracting useful information, then conducting research and generalization of the data.

We generally divide machine learning into four categories: supervised learning, unsupervised learning, self-supervised learning, and reinforcement learning.

Machine learning starts from data calculations. Many algorithms pay more attention to how to calculate, rather than mathematical results.

Machine learning is divided according to the output space, including different types such as binary classification, multiple classification, regression, and structured learning.

The working principles of different database engines are very different, which ultimately leads to differences in the performance of MySQL database services.

MySQL's official definition of index is: Index is a data structure that helps MySQL obtain data efficiently.

MySQL currently has the following index types:1. Ordinary index 2. Unique index 3. Primary key index 4. Combined index 5. Full-text index

MySQL has several different log files, usually including error log files, binary logs, general logs, slow query logs, and so on.
