Data Business Analyst PLSQL, T-SQL & Data Warehousing

Data Business Analyst - PL/SQL T-SQL & Data Warehousing

Job Responsibilities

1. Analysis of Legacy Systems

• For each use case analyze the mapping document of target tables to determine operational objectives by studying business functions gathering information and evaluating output requirements.
  
• Track the target field mapping back to the original data element in the source system.
  
• Strong knowledge of SQL to perform data analysis and data profiling on different legacy systems.
  
• Document the existing source-to-target data flow for each table including:
  • Business transformation rules applied.
    
  • Key-cutting implemented to identify surrogate keys defined as unique identifiers in a table.
    
  • Reference data used to enhance the context and validity of target data elements.
    
• For tables where mapping documentation is not available TSBI and ETL leads must jointly review the code to extract business rules and capture them in the requirements document.
  

2. L2/L3 Model

• The business team is responsible for the creation of the L2 Model supported by the Project Business Analyst Solution Architect and TSBI.
  
• Collaborate with data scientists business analysts and IT teams to integrate advanced L2/L3 models into the data pipeline.
  

3. Mapping Design of New L2/L3

• Prepare technical design and mapping (Data Movement Model) for the new L2 Model by working with Project Business Analysts and Solution Architects.
  
• Review the key-cutting process to be implemented on the L2 model and obtain approval from L2 Schema Owners.
  
• Only BORT system data will be populated into the L2 schema; other reference and tactical data will be directly consumed by L3 processes.
  
• L2-to-L3 mapping will contain business transformation rules for each target table.
  
• A custom surrogate key process will be implemented on L3 tables which will contain different keys than L2 tables.
  
• Any system with one-off tables holding business data will be loaded into the L3 schema for target table processing.
  
• Spearhead the implementation of robust data governance policies and procedures ensuring compliance with industry regulations and standards resulting in a 20% reduction in data security incidents.
  
• Collaborate with cross-functional teams to design and implement data quality frameworks improving data accuracy and integrity while reducing errors.
