Data cleansing and validation

Clean, reliable data — for the long term.

We systematically identify and resolve issues in existing datasets — duplicates, missing and conflicting values, outdated records — and implement built-in rules to ensure data remains clean over time.

measured data quality · careful review · maintained quality

Not a one-time clean-up where the data becomes messy again six months later. Built-in validation ensures the data is not only clean today, but stays clean in the future as well.

THE PROBLEM

Poor data becomes accepted and worked around

Everyone knows about the problem of “duplicate items” or “outdated records”, but nobody owns it and there is no metric attached to it.

“the same item appears under multiple names and item codes” — duplicates distort reporting

“many fields are empty or outdated” — incomplete data leads to poor decisions

“everyone records data in a different format” — data becomes difficult to compare and search

Does this sound familiar?

If you recognise any of these situations, it is worth spending 30 minutes reviewing whether Data cleansing and validation is the right solution for your organisation.

WHAT IT DOES IN PRACTICE

A family of capabilities, assembled as needed

Data quality audit

We first show the problem with numbers — not assumptions.

Duplicate management

Identifying and merging records that represent the same entity.

Missing and incorrect data

Completion, flagging and correction of clearly incorrect values.

Normalisation and standardisation

Dates, addresses, phone numbers and names — converted into a consistent format.

Validation rules

Errors can be detected at the point of entry — helping data remain clean over time.

Continuous monitoring

Recurring checks ensure deterioration is identified early.

You know there are issues in the data — you just do not know how serious they really are.

The most common situation is that everyone senses there is a data quality problem, but nobody can clearly see its scale. Through a data quality audit, we quantify the issues and show where to start improving.

THE PRINCIPLE

Duplicate detection is not deletion

“Remove the duplicates” sounds simple, but deciding what truly represents the same entity requires experience and a careful, controlled approach.

We start with auditing and measurement

We quantify the issues first — without this, cleansing becomes guesswork.

No deletion without review

Anything that cannot be determined with certainty is flagged and reviewed rather than deleted — helping prevent data loss.

WHY OMNIT

What makes us different

Measurable data quality

We begin with an audit, show the issues with numbers and measure the improvement as well — making the results visible.

Maintained, not one-time

Most cleansing projects become messy again within six months. We implement rules to keep the data clean.

15+ years of data engineering and data quality experience

We know the most common data quality issues and how to handle them carefully without causing data loss.

FREQUENTLY ASKED QUESTIONS

Before you start

It might be — which is why we start with an audit that shows the actual condition through numbers. We do not assume; we measure.

That is valuable — but without validation rules, data quality deteriorates again as new records arrive.

A fair question — which is why every uncertain case is reviewed and discussed separately.
