GLOBAL FINANCIAL SERVICES FIRM

Automated Hyperion SQR to Oracle Analytics Server Migration for a Global Financial Firm

Customer Background

A Financial Firm Modernizing
Legacy SQR Reporting

A large international financial firm relied on a substantial portfolio of Hyperion SQR reports across investment banking, commercial lending, private equity, and compliance. As Hyperion SQR aged, became increasingly unsupported, and grew costly to maintain, the firm needed to modernize to a supported, scalable BI platform without disrupting daily reporting.

The firm engaged DataTerrain for an Automated Hyperion SQR-to-Oracle Analytics Server (OAS) migration, a fixed-cost, automation-driven approach that replicates each report's original layout, structure, and business logic in OAS. The scope covered 200 reports, each of which had to be generated in both CSV and PDF.

The Challenge

Preserving Exact Reporting While Solving Output
and Logic Gaps

Migrating 200 business-critical reports from Hyperion SQR to Oracle Analytics Server meant preserving exact functionality while solving several platform-specific problems, particularly around output generation and where business logic lived:

Dynamic CSV output

OAS has no straightforward way to produce CSV built at runtime from the specific columns a user selects, yet the reports required exactly that.

Dual CSV and PDF delivery

Each of the 200 reports had to be generated in both CSV and formatted PDF formats.

Database-level business logic

Complex business logic and functions were implemented at the database level, invoked from the report data model, and had to remain unchanged.

User-based data formatting

Output formatting had to vary according to the user logged into the server.

Accuracy and continuity

The report structure, filters, and business logic had to be preserved so users could continue working without disruption or retraining.

Our Approach

Automation-Driven Conversion with Targeted Engineering

DataTerrain's automation tool handled the bulk of the Automated Hyperion SQR to OAS migration, with targeted engineering for the platform-specific challenges:

1

Dynamic, column-driven CSV

With no native OAS mechanism for runtime CSV, DataTerrain used an XSL template to generate a dynamic text file based on the columns selected at runtime, then had the application rename the .txt output to .csv, delivering accurate, column-specific CSV for every report.

2

Dual CSV and PDF output

Each of the 200 reports was configured to generate in both CSV and PDF, so the same report can be consumed as formatted output or as raw data.

3

Database-level logic reused in the data model

The complex business logic and functions already proven at the database level were retained and called directly from the OAS data model, preserving results and performance while avoiding risky re-implementation.

4

User-aware data formatting

Formatting was driven by the user logged into the server, so each user sees output formatted for their profile and entitlements.

5

Automation-driven conversion and validation

DataTerrain's automation tool replicated each report's original layout, structure, and logic in OAS, with testing and stakeholder validation confirming accuracy before rollout.
