Connected information
Bring relevant operational sources into a consistent destination for reporting, applications, or analysis.
CONNECTED ENTERPRISE DATA
ETL as a Service
Bring your systems together. Keep the logic clear.
Integrate fragmented data sources through maintainable extraction, transformation, and loading workflows tailored to your business rules and operating environment.
THE OPPORTUNITY
Create a dependable path from source to destination.
As organizations add applications, data often becomes scattered across databases, SaaS platforms, files, and external feeds. Reporting teams compensate with manual exports and one-off transformations that are difficult to trace or maintain. GKAICORE helps replace those disconnected processes with clear integration workflows that move data consistently and preserve its business meaning.
Our ETL service covers discovery, source mapping, transformation, validation, and deployment, with ongoing operation available through an agreed engagement scope. We support both ETL and ELT patterns, choosing where transformations run based on your platform capabilities, governance requirements, and workload. Your team receives documented logic and an understandable integration model rather than an opaque collection of connectors.
Traceable transformations
Make data mappings and business rules understandable to the people who own and consume the results.
Maintainable integration
Create a repeatable approach to onboarding new sources and managing change over time.
SERVICE CAPABILITIES
Built around the complete operating requirement.
A focused set of capabilities, tailored to your sources, systems, and business priorities.
Source discovery & integration
Inventory applications, interfaces, ownership, and access requirements. Plan extraction around API limits, source availability, schema behavior, and the effect of additional load on operational systems.
Source-to-target mapping
Define how source fields become target entities, attributes, and measures. Make keys, reference data, type conversions, defaults, and business exceptions explicit before implementing transformations.
Transformation & standardization
Clean and normalize records, apply business rules, and integrate data across sources. Structure transformations for review and reuse, with a clear distinction between source correction and business interpretation.
Incremental loading & history
Choose incremental strategies and historical retention patterns that fit the available source data. Handle updates, deletions, and late corrections without silently losing changes or rebuilding everything unnecessarily.
Validation & exception handling
Check input and output expectations, reconcile control totals, and route rejected records for investigation. Define how errors are corrected, reprocessed, and communicated to data owners.
Monitoring & change management
Track freshness, failures, and extraction health. Establish how connector updates, schema changes, credentials, and business-rule revisions are tested and introduced into ongoing workflows.
WHERE IT FITS
Practical applications for your business.
CRM, billing & ERP integration
Unify customer, account, order, and payment data while preserving source ownership and reconciliation requirements.
Warehouse or lake modernization
Rebuild legacy integration flows for a new destination with explicit mappings, parallel validation, and a controlled cutover.
External data onboarding
Ingest partner feeds and third-party datasets with validation, exception handling, and a repeatable source onboarding process.
OUR DELIVERY APPROACH
A clear path from requirements to operation.
Discover sources
Review source access, volumes, ownership, interface constraints, and downstream information needs.
Map & agree rules
Document target structures, transformation logic, acceptance checks, and exception-handling responsibilities.
Implement & validate
Build integrations in stages and reconcile outputs using representative source data and business scenarios.
Deploy & support
Release with monitoring, documented recovery, and an agreed process for ongoing changes and support.

COMMON QUESTIONS
Before we get started.
What is the difference between ETL and ELT?
ETL transforms data before loading it into the main analytical destination. ELT loads data first and uses the destination platform to perform transformations. We select the approach around governance, source sensitivity, platform capabilities, and workload rather than treating one pattern as universally preferable.
Can you preserve our existing business logic?
Yes. We document current rules, identify ambiguous behavior, and agree reference outputs with business owners. During migration, we compare the new results with those references and investigate differences before cutover.
How are changes in source systems handled?
We identify the changes that can be detected automatically and those that require coordination with source owners. Schema checks, interface monitoring, version control, and controlled deployment help manage the effect of source or business-rule changes.
Is ongoing operation included?
Ongoing monitoring, maintenance, and support can be included in an agreed service scope. Coverage hours, incident responsibilities, change requests, and third-party dependencies are defined explicitly so your team knows what to expect.
