Trend Analysis: Examining data over time to identify upward or downward trends.

Seasonal Patterns: Identifying recurring patterns or trends based on seasons or specific time periods

Correlation: Understanding relationships between variables and how changes in one may affect another.

Outlier Detection: Identifying data points that deviate significantly from the overall pattern.

Clustering: Grouping similar data points together to find natural patterns within the data.

Classification: Categorizing data into predefined classes or groups based on certain features.

Regression Analysis: Predicting a dependent variable based on the values of independent variables.

Frequency Distribution: Analyzing the distribution of values within a dataset.

Pattern Recognition: Identifying recurring structures or shapes within the data.

Text Analysis: Extracting insights from unstructured text data through techniques like sentiment analysis or topic modeling.

These patterns help organizations make informed decisions, optimize processes, and gain a deeper understanding of their data.

HTTP status codes β€” quick cheat sheet

βœ… 200 OK: request succeeded
πŸ†• 201 Created: new resource saved
πŸ“ 204 No Content: success, nothing to return
πŸ”€ 301 Moved Permanently: use new URL

πŸ› οΈ 502 Bad Gateway: upstream failed
πŸ•ΈοΈ 503 Service Unavailable: overloaded/maintenance
βŒ› 504 Gateway Timeout: upstream too slow

tips
β€’ return precise codes; don’t default to 200/500
β€’ include a machine-readable error body (code, message, details)
β€’ never leak stack traces in production
β€’ pair 304 with ETag/If-None-Match for caching
