This diagram illustrates an AI Prediction System workflow, which is divided into two main sections:

  1. Upper Section (VIEW):
  • Starts with a UI/UX interface
  • Executes queries with tags (metadata)
  • Connects to time series data storage
  • Displays data visualization charts
  • Includes model selection step
  • Finally generates prediction charts
  1. Lower Section (Automation):
  • Selected ID
  • Selected Model
  • Periodic, new tags and additional configuration
  • Batch work processing (consisting of 4 steps):
    1. Registering
    2. Read Data
    3. Generate Predictions
    4. Add Tag
  • Writing new time series data

The system provides two main functionalities:

  1. A user interface for direct data viewing and prediction execution
  2. Automated batch processing for periodic predictions and data updates

Key Components:

  • Time Series Data storage as a central database

This image is a diagram showing the data processing flow from TSDB (Time Series Database) to RDBMS (Relational Database Management System). Let me explain the main components and processes:

  1. Data Collection Stage:
  • Analog to Digital (conversion from analog to digital)
  • Time (time information)
  • Meta data
    These three elements combine to generate Time Series Data.
  1. ETL (Extract, Transform, Load) Processing: Data is processed through two paths:
  • Upper path:
  • Easy Calculation
  • Shorter Time Range
  • Stored in Time Series Database
  • Lower path:
  • Complex & Programmatic processing
  • Bigger Time Range
  • Stored in Relational Database
  1. Final Data Utilization:
  • Raw Data → Realtime Monitoring
  • Analyzed Data → Monitoring & Prediction

This diagram explains the overall data pipeline showing how time series data is collected, processed, and ultimately utilized for real-time monitoring and predictive analysis.

CDC & ETL

Posted on by lechuck park

From Claude with some prompting
Here’s the interpretation of the image explaining CDC (Change Data Capture) and ETL (Extract, Transform, Load) processes. The diagram is divided into three main sections:

  1. Top Section:
  • Shows CDC/ETL process from “For Operating” database to “For Analysis” database.
  1. Middle Section (CDC):
  • Illustrates the Change Data Capture process
  • Shows how changes C1 through C5 are detected and captured
  • Key features:
    • Realtime processing
    • Sync Duplication
    • Efficiency
  1. Bottom Section (ETL):
  • Demonstrates traditional ETL process:
    • Extract
    • Transform
    • Load
  • Processing characteristics:
    • Batch process
    • Data Transform
    • Data Integrate

The diagram contrasts two main approaches to data integration:

  1. CDC: Real-time approach that detects and synchronizes changes as they occur
  2. ETL: Traditional batch approach that extracts, transforms, and loads data

This visualization effectively shows how CDC provides real-time data synchronization while ETL handles data in batches, each serving different use cases in data integration strategies.
