Unbounded Array Framework (UAF) Overview

The Unbounded Array Framework is Teradata's analytics framework for:

• End-to-end time series forecasting pipelines
• Digital signal processing for radar, sonar, audio, and video
• 4D spatial analytics and image processing
• Scalable analysis of high-dimensional data
• Complex use cases across multiple industries

UAF functions process:

• One-dimensional series indexed by time or space
• Two-dimensional arrays (matrices) indexed by time, space, or both
• Large datasets with robust scalability

Table Analysis Workflow

This skill automatically analyzes your time series data to generate optimized UAF workflows:

1. Time Series Structure Analysis

• Temporal Column Detection: Identifies time/date columns for indexing
• Value Column Classification: Distinguishes between numeric time series values
• Frequency Analysis: Determines sampling frequency and intervals
• Seasonality Detection: Identifies seasonal patterns and cycles

2. UAF-Specific Recommendations

• Array Dimension Setup: Configures proper 1D/2D array structures
• Time Indexing: Sets up appropriate temporal indexing
• Parameter Optimization: Suggests optimal parameters for TD_MAMEAN
• Pipeline Integration: Recommends complementary UAF functions

3. SQL Generation Process

• UAF Syntax Generation: Creates proper Unbounded Array Framework SQL
• Array Processing: Handles time series arrays and matrices
• Parameter Configuration: Sets function-specific parameters
• Pipeline Workflows: Generates complete analytical pipelines

Example Usage

-- Example TD_MAMEAN workflow
-- Replace parameters with your specific requirements

-- 1. Data preparation for UAF processing
-- Use EXECUTE FUNCTION syntax:
-- EXECUTE FUNCTION INTO VOLATILE ART(mamean_results)
-- TD_MAMEAN(
--     SERIES_SPEC(TABLE_NAME(input_table), SERIES_ID(id_col),
--         ROW_AXIS(TIMECODE(time_col)),
--         PAYLOAD(FIELDS(value_col), CONTENT(REAL))),
--     FUNC_PARAMS(WINDOW_SIZE(7), FORECAST_PERIODS(12))
-- );
-- SELECT * FROM mamean_results;

-- 2. Execute TD_MAMEAN
-- Use EXECUTE FUNCTION syntax:
-- EXECUTE FUNCTION INTO VOLATILE ART(mamean_results)
-- TD_MAMEAN(
--     SERIES_SPEC(TABLE_NAME(input_table), SERIES_ID(id_col),
--         ROW_AXIS(TIMECODE(time_col)),
--         PAYLOAD(FIELDS(value_col), CONTENT(REAL))),
--     FUNC_PARAMS(WINDOW_SIZE(7), FORECAST_PERIODS(12))
-- );
-- SELECT * FROM mamean_results;
