NexusGreenDataA data governance platform built around the National Data Index (Nudee) issued by the Saudi Data and AI Authority (SDAIA). It covers all three components of the index, from data management maturity to NDMO compliance and data quality, and gives the entity a clear view of where it stands in every domain and what to do next. The result is a guided path from the «Establishing» level to «Pioneer».
NexusGreenDataIndex components
The Nudee index measures an entity from three angles: data management maturity, compliance with the NDMO controls, and data quality. The platform addresses all three in one place, on a single data catalog.
The platform tracks the 42 maturity questions across the 14 data management domains and shows an estimated score per domain on the five maturity levels. The entity sees where it stands today and what separates it from the next level.
Each of the 191 specifications under the 77 controls is linked to a compliance status, an owner and evidence. Unmet specifications automatically become owned tasks through the gap-to-action recommendations.
The data quality module runs on the same data catalog, so rules are measured against real data assets rather than descriptions. Results feed the score board alongside the maturity and compliance indicators.
NDMO controls
The National Data Management controls are the requirements issued by the National Data Management Office (NDMO) that define how entities govern, manage and protect their data, organised into 15 knowledge domains, 77 controls and 191 specifications. The platform ships with these specifications preloaded and ties each one to a named owner and to the evidence that proves it is met, whether a document, a register or a data asset in the catalog. The compliance status of every control is therefore known and auditable at any time.

Raising the score
Four capabilities turn the index requirements into organised, day-to-day work inside the entity.
The board shows estimated maturity and compliance scores for every domain and every one of the five levels. It helps the entity set priorities and track progress from one review to the next, while the official score remains SDAIA’s.
Every unmet specification becomes a task with an owner, a due date and an expected effect on the score. The entity moves from a list of findings to a plan it can execute and follow up.
The platform provides 380 ready evidence templates linked to real data assets in the built-in data catalog. Documents and registers are kept beside the specification they support, which makes audits faster and less disruptive.
The platform is deployed on the entity’s own infrastructure, so data never leaves its boundary. The bilingual Arabic and English interface serves data teams and compliance teams alike.

The challenge
Saudi entities are measured against the NDMO standards, the National Data Index and PDPL, while the evidence lives in spreadsheets, folders and inboxes that are out of date the day they are finished.
The platform
The journey starts with the National Data Index: the official domains, controls and specifications, each tied to its maturity question and the evidence required at every level, from Establishing to Pioneer.
A complete self-assessment of SDAIA's National Data Index: NDMO domains, 191 specifications and 42 maturity questions, each linked to evidence and an owner.
The public interactive chart presents every domain, control, specification and maturity question of the index and can be explored without signing in.
Duplicates are resolved into golden records, reference sets stay consistent across systems, and the PDPL registers run on the same catalog.
Duplicated records are resolved into one golden version of each entity through matching, survivorship rules and stewardship.
Code sets and controlled lists stay consistent across systems, with versions, hierarchies and governed change.
The Personal Data Protection Law registers run where the data lives: classification, RoPA, DSAR and breach records.
Data is scored against the NDMO quality dimensions, sensitive data is classified, and assessor-ready packs are exported in both languages.
Data is measured against the NDMO quality dimensions with rule-based tests, and every failure becomes a tracked issue.
Data Classification and BI and Analytics governance ship today as backend modules: classification schemes, coverage reports, use-case register and certification.
Catalog foundation
The governance modules run on an enterprise data catalog with the capabilities a modern data office expects. Every module reads and writes the same assets, so evidence, golden records and quality results stay connected.

How it works
NexusGreenData connects to the entity's data catalog and sources and reads assets, columns, lineage, glossary terms and policies through documented interfaces.
Assets are mapped to NDMO domains, controls and specifications; reference and master data, classification, protection policies and quality rules are defined.
National Data Index maturity and compliance are estimated, quality checks run and PDPL registers tracked. Every number is labelled Estimated with a data-freshness indicator.
Evidence, scorecards and assessor-ready exports are generated in Arabic and English, and golden records and lineage are written back to the catalog.

FAQ
Nudee is an index issued by SDAIA that measures data management maturity, compliance with the NDMO controls and data quality in government entities. It places each entity on five levels from Establishing to Pioneer and highlights its strengths and improvement areas.
It tracks all 191 compliance specifications, manages evidence and documents, and turns gaps into owned recommendations backed by a score board. Each specification is tied to an owner and evidence, so the entity always knows what is met, what remains and who is responsible.
The index consists of data management maturity, compliance with the NDMO controls, and data quality. The platform covers all three on a single data catalog, so their results appear together on one score board.
The controls are 77 high-level requirements spread across 15 knowledge domains, while the specifications are 191 detailed items that define what must be in place to satisfy each control. The platform works at specification level, tying each item to its evidence and owner.
Yes, the platform is deployed on the entity’s own infrastructure, so data, evidence and documents stay within its boundary. The interface works in both Arabic and English with no dependency on any external service.
No, the platform’s scores are estimates that help the entity prepare and prioritise ahead of the assessment. The official National Data Index score is issued by SDAIA alone, according to its own assessment process.
NexusGreenData is a data governance platform for Saudi public and private entities. It brings the National Data Index self-assessment, master and reference data management, PDPL privacy and data quality onto one data catalog, and takes an entity from Establishing to Pioneer on the index.
Yes. The index's data-management domains, their controls and all 191 specifications, the 42 maturity questions with the evidence required at each of the five levels, 380 ready evidence templates, the required KPIs and the operational-excellence indicators are all built in, so an entity can plan and track its progress from Establishing to Pioneer.
Shipped modules: NDI Maturity Index, Master Data Management, Reference Data Management, Privacy and PDPL, and Data Quality. Data Classification and BI and Analytics governance ship as backend modules today.
No. Every maturity, compliance and operational-excellence number is an estimate for internal planning, labelled Estimated with a data-freshness indicator. SDAIA's NDI platform remains the official system of record.
On-premises or in the entity's own cloud. The platform reads the data catalog through documented interfaces; no data leaves the environment and no connection to a national platform is required.
Yes. The platform is fully Arabic and English with right-to-left support. Arabic terminology follows the national standards rather than machine translation.
