Migrate Legacy Code to Pandas

The SAS2PY platform migrates legacy analytics and data processing workflows into Pandas, enabling efficient **data manipulation, transformation, and analysis within a Python environment.

Pandas supports structured data operations such as **data cleaning, aggregation, filtering, statistical analysis, and feature engineering. It allows seamless integration with CSV, Excel, JSON, Parquet, SQL databases, and APIs**, making it ideal for handling structured datasets.

The migration process converts legacy SAS data structures, tables, and scripts** into Pandas-based workflows, enabling businesses to modernize their data exploration, reporting, and analytics with Python's rich ecosystem.

STEP 1: Legacy Analysis

Automatically analyzes the legacy environment and identifies all legacy components, such as SAS Base, DI Studio, Informatica, SQL scripts, or database dependencies (e.g., Oracle, Teradata).

Pandas SQL Notebooks:
Pushes converted code directly into Pandas Workspaces for seamless collaboration.

Pandas Workflows:
DB invokes SAS2PY API to convert code in S3 or elsewhere.
STEP 2: Code Conversion

Syntax Conversion:
Parse SAS, SQL, or ETL workflows and convert them into Pandas SQL or Pandas-compatible scripts.

Schema Translation:
Adapt legacy database schemas to Pandas Delta Lake architecture, ensuring ACID compliance and optimal performance.

ETL Modernization:
Replace legacy ETL workflows (e.g., Informatica) with Delta Lake-native pipelines for scalable, modern data processing.

Push Models:
Export converted workflows directly to Pandas Workspaces for immediate use.

Pull Models: Use Pandas to interact with SAS2PY APIs for data transformation and migration, enabling processing of structured datasets from storage solutions like S3, databases, or local files.

Code Optimization:
Refactor inefficient or outdated logic to enhance Pandas processing performance. For larger datasets requiring scalability and distributed execution, integration with Dask, Modin, or PySpark can be leveraged.













STEP 3: GenAI Validation & Testing

Leverage cutting-edge Generative AI to analyze, optimize, and validate the converted legacy code, ensuring a fully optimized solution within PySpark.

Data Validation:
Automate checks to confirm parity between legacy outputs and Pandas results, ensuring the integrity of data migration.

Regression Testing:
Compare outputs of migrated workflows with legacy systems to maintain consistency across operations.

Error Handling:
Identify and resolve syntax errors, data inconsistencies, or logic gaps during the testing phase to ensure production readiness.
Data Matching

Automated Schema Mapping:
Automatically maps source schemas (e.g., SAS, Oracle, Teradata) to pandas.

Data Type Validation:
Ensures that column types (e.g., numeric, string, date) in the legacy system are correctly translated into pandas-native formats.

Metadata Comparison:
Compares metadata (e.g., table structures, indexes) between legacy and pandas systems to guarantee structural alignment.

Metrics Comparison:
Validates key metrics such as counts, sums, averages, and other aggregates between source and target systems.

Partitioned Validation:
Supports aggregate checks at the partition level (e.g., by date or region) to ensure consistency across subsets of data.







The Power of Pandas

Businesses transitioning from static, on-premise analytics systems to modern Python-based data processing can enhance efficiency and flexibility with Pandas.

Versatile Data Processing: Handle structured and semi-structured data, enabling data cleaning, transformation, aggregation, and statistical analysis.

High-Performance In-Memory Computation:
Perform efficient operations on large datasets using Pandas' vectorized computations and optimized built-in functions.

Seamless Data Integration:
Easily read and write data in multiple formats, including CSV, Excel, JSON, Parquet, and SQL databases, enabling smooth interoperability with cloud storage and databases.

Enhanced Data Reliability:
Ensure data integrity with built-in methods for handling missing values, duplicates, and complex transformations.

Scalability Strategies:
While Pandas operates in-memory, large datasets can be managed using efficient chunking, optimized I/O operations, or integrations with Dask and Modin for improved scalability.

Cloud & Remote Accessibility:
Run Pandas notebooks in Jupyter, Google Colab, or VS Code, enabling teams to analyze and process data in cloud-based environments.
