Data Governance & Data Quality

Poor Data Quality Turns Reports Into Bad Decisions

Data governance is the set of rules and responsibilities that decides where each piece of data is held, who owns it, how it is defined and which quality rules it must meet. Data quality work puts that into practice: records are measured, duplicates and errors are cleaned up, and entry rules are added so the same mistakes do not return.

The same customer appears under three different names, one product carries different codes in the warehouse and in sales, and marketing and finance each have their own count of "active customers". A new reporting tool or ERP will not fix that; it simply shows the wrong answer faster and more attractively. Meanwhile invoices go to the wrong account, stock is counted twice and the same person receives a campaign three times.

Digital Bridge maps your data, measures its quality, cleans up the faulty records and gives every data set an owner. We are not here to sell you another piece of software. The goal is to make the data in the systems you already have reliable, and to put entry rules, regular measurement and clear responsibilities in place so it stays that way.

Data governance and data quality: data inventory, duplicate record cleansing and quality measurement

What Data Governance Work Covers

Data Inventory & Flow Map

Where each piece of data is created, where it is copied to and which reports it feeds is mapped end to end. Spreadsheets and side lists kept outside the official systems come to light as well.

Data Dictionary & Shared Definitions

Terms such as "active customer", "net sales" or "stock on hand" get a written, organisation-wide definition, so every department answers the same question with the same number.

Ownership & Accountability

Each data domain, such as customers, products or employees, gets an owner and a steward. Requests to create, correct or access records follow a defined approval flow.

Cleansing & Duplicate Merging

Spelling variants, missing fields and duplicate records are identified, and merge decisions are taken together with the business team. Company names, addresses and tax numbers are brought into one standard format.

Quality Measurement & Monitoring

Completeness, uniqueness, validity and consistency are measured and reported at regular intervals. When a field drops below the agreed level, the person responsible for that data is alerted.

Personal Data Inventory

Which system holds which personal data, for what purpose and for how long, documented in line with Turkey's data protection law (KVKK). For the full compliance programme, see data protection compliance.

When You Need a Data Quality Project

  • Before starting a BI or reporting project
  • Data cleansing ahead of an ERP migration
  • Bringing data together after a merger or acquisition
  • Deduplicating customer records in the CRM
  • Preparing data for AI projects
  • Data standardisation in public bodies
  • Aligning branch and dealer data to one set of rules
  • Preparing for audits and statutory reporting

How We Work

01
Current-State Review

We review your systems, data flows and the reports you rely on, and list the priority data domains and the problems your teams already know about.

02
Quality Measurement & Report

We measure the selected domains and put numbers on it: how many records are faulty and what that means for invoicing, stock or reporting.

03
Cleansing & Entry Rules

We clean the data, then add mandatory fields, format checks and duplicate warnings so the same errors do not creep back in.

04
Ownership & Handover

Data stewards are appointed, a regular quality report is set up and the process is handed over to your in-house team.

Clean First, Analyse Second

Before a BI, demand forecasting or AI integration project, we recommend measuring your data quality. A model trained on bad data automates bad decisions, and because the model gets the blame, the real cause can go unnoticed for a long time. Clean data is a solid starting point for a data warehouse and BI dashboards.

Questions we hear most often

Frequently Asked Questions

What is data governance?

Data governance is the set of rules and responsibilities that decides where each piece of data is held, who owns it, how it is defined and which quality rules it must meet. In practice it means a data inventory, a data dictionary with shared definitions, an owner and steward for each data domain, and a defined approval flow for creating, correcting or accessing records.

How is data quality measured?

Data quality is measured with indicators such as completeness, uniqueness, validity and consistency. For the selected data domains, we put numbers on how many records are faulty and what that means for invoicing, stock or reporting. Measurement is repeated at regular intervals, and when a field drops below the agreed level, the person responsible for that data is alerted.

How are duplicate customer records cleaned up?

Spelling variants, missing fields and duplicate records are identified, and merge decisions are taken together with the business team. Company names, addresses and tax numbers are brought into one standard format. After the clean-up, mandatory fields, format checks and duplicate warnings are added to the system so the same errors do not creep back into new records.

When does a business need a data quality project?

Typical triggers are starting a BI or reporting project, preparing for an ERP migration, bringing data together after a merger, and deduplicating customer records in the CRM. Preparing data for AI or demand forecasting, aligning branch and dealer data to one set of rules, and getting ready for audits or statutory reporting are also common starting points.

What are the steps of a data governance project?

We work in four steps: a review of your systems, data flows and reports; quality measurement and a report on the selected domains; cleansing plus entry rules added to the system; and finally appointing data stewards, setting up a regular quality report and handing the process over to your in-house team. The aim is reliable data in the systems you already have, not new software.

How does data governance relate to KVKK and personal data?

A personal data inventory is part of data governance. The work documents which system holds which personal data, for what purpose and for how long, in line with Turkey's data protection law (KVKK). For the rest of the compliance programme, such as privacy notices and retention policies, it can be combined with our data protection compliance service.
