DS Srishti
Building governed medallion lakehouses where the data model is derived from evidence — not drawn in workshops.
Brownfield vs. Greenfield Modernization
DS Srishti adapts seamlessly to your architectural starting point while delivering the exact same governed medallion lakehouse destination.
BROWNFIELD
ALL 7 STAGESStarting point: a legacy warehouse and the ETL estate around it.
GREENFIELD
5 STAGESStarting point: source systems directly — ERP, CRM, operational, APIs, streams.
Seven-Stage Operating Model
Nothing advances on assumption. Every stage produces an inspectable artifact that can be reviewed before the next begins.
Estate Inventory & Scoring
Inventory tables, views, procedures, ETL jobs, and reports. Score complexity objectively and forecast automation rate.
End-to-End Lineage
Reconstruct column-level lineage across legacy data warehouse, ETL scripts, and BI report universes.
Legacy Object Retirement
Identify and retire unused tables, redundant ETL jobs, and duplicate reports before paying to convert them.
Medallion Model Derivation
Derive medallion lakehouse model (Bronze/Silver/Gold) from evidence and real query usage — not workshops.
Automated Conversion
Perform agentic process conversion for ETL jobs, SQL, stored procedures with syntax validation and reconciliation.
Certified Metric Catalog
Publish certified metric definitions, KPI business logic, and semantic layer schemas for single source of truth.
Data Product Self-Service
Enable governed self-service, real-time analytics, and data product API publishing for AI & BI consumers.
Legacy-to-Medallion Transformation
Each legacy layer is re-expressed agentically as the medallion layer that now performs its job.
| LEGACY LAYER | WHAT SRISHTI DOES | TARGET MEDALLION LAYER |
|---|---|---|
| Source Systems | Connect directly; extraction logic regenerated rather than simply repointed. | SOURCES |
| Staging / Landing Area | Convert into an immutable, partitioned, replayable landing layer. Nothing overwritten in place. | BRONZE |
| ODS / Integration Layer | Lift cleansing, deduplication, and conformance logic out of legacy ETL and express as governed transformations. | BRONZE → SILVER |
| EDW Core / 3NF | Re-derive the normalised core as conformed domain entities, business keys, and SCD strategy. | SILVER |
| Data Marts / Star Schemas | Rebuild marts as domain data products attached with contract, owner, quality SLA, and lineage. | GOLD |
| BI Semantic / Universes | Convert universe and report logic into a single certified semantic and KPI layer. | SEMANTIC |
Target Medallion Lakehouse
Sources → Bronze → Silver → Gold → Semantic / Consumption. Open table formats throughout; every layer governed.
BRONZE
raw · immutable · replayable
- ✓Data landed exactly as received from source systems
- ✓Partitioned by source system and load date
- ✓Full replay possible without re-extraction from sources
- ✓Schema drift logged automatically; changes never silently dropped
SILVER
cleansed · conformed · governed
"Silver is where the enterprise model actually lives."
- ✓Deduplicated and standardized domain entities
- ✓Conformed business keys across enterprise domains
- ✓Slowly Changing Dimensions (SCD Type 1/2) handling
- ✓Automated survivorship and conflict resolution rules
GOLD
data products · business-ready
"Gold outputs are treated as managed, versioned data products."
- ✓Domain-specific marts and aggregated analytical models
- ✓Published semantic contracts and versioned interfaces
- ✓Enforced quality SLAs (Freshness, Completeness, Accuracy)
- ✓Registered in catalog with business glossary and lineage
Governed Data Products
"A table is something you query. A data product is something you can depend on."
Named Owner
Accountable steward and domain owner for every product
Schema Contract
Published, versioned interface; breaking changes visible before consumer impact
Quality SLA
Automated freshness, completeness, and accuracy checks on every load
Full Lineage
Source table → field → transformation → product tracing for engineers & auditors
One Definition
Single certified KPI meaning across dashboards, ML models, and AI agents
Discoverability
Catalog registration with glossary terms for self-service discovery without requests
Comprehensive Platform Coverage
DS Srishti supports virtually every major legacy data warehouse, ETL engine, modern cloud platform, and reporting tool.
The reporting layer is converted too — OBIEE, Cognos, BusinessObjects, SSRS and MicroStrategy logic migrated alongside the data, so the whole estate lands together.
Deterministic, syntax-validated generation of targets
Successfully delivered across global enterprise estates
Across legacy warehouse, ETL, and procedure environments
Evidence-Gated Engagement Model
You see proof before committing to the next phase. Nothing is taken on trust.
ASSESSMENT
Full estate inventory, column-level lineage, usage profiling, and objective complexity scoring.
MODEL & PILOT
Derive medallion model, review with customer architects, convert a representative slice end-to-end, and reconcile results.
INDUSTRIALIZE
Full conversion in waves organized by domain, validation on every load, reconciliation, and publishing Gold data products.
TRANSITION
Runbooks, enablement, train-the-trainer, platform operations handover, and hypercare through stabilization.
