Central Data Validation

Real-time validation is the brand new method of data cleansing that, in a preventive way, monitors and corrects master data prior to entry and storage into the database. Quality Monitor is a proprietary tool based on step-by-step methodology that offers entry opportunities for companies situated on different levels from a data quality point of view. The solution puts an end to the idea that data cleansing activity needs to be performed again and again from time to time. As a unique tool on the market, it offers a solution to the creation of perfect quality data.

How it works

Comprehensive Data Quality Assessment

Comprehensive Data Quality Assessment

  • Assessing the company’s current data quality level
  • Identifying current data quality problems and defining tasks to be performed
  • The customer receives a data quality assessment report document about current data quality level and issues
  • Requires minimal time, usually only a few weeks

Data Cleansing and Deduplication

Data Cleansing and Deduplication

  • Combines automated (and manual) data cleansing methods, deduplication processes or data enrichment tasks to reach high level of data quality
  • Understanding unique customer needs, data quality expectations through consultations
  • Non-conformities (like data errors, data gaps, duplicates) are resolved
  • Clean data state is achieved

Ensuring continuous data quality

Ensuring continuous data quality

  • Implementing our iQualidator real-time data validation solution on the online data entry points and the offline batch interfaces
  • Data entry points and data channels are correctly configured, monitored and corrected all in the same way and with the same methodologies
  • Continuously correct and duplicate-free data quality is ensured prior to entry and storage into the database, in a preventive way
  • Regular reports to prove the success of the implementation


Data Cleansing

Detecting and correcting (or removing) corrupt or inaccurate records from a record set, table or database with algorithmic tests (where data is inferred using mathematical algorithms), as well as comparing data to a valid reference database and determining the correct value based on the comparison.

Name Cleansing

Fixing incorrectly entered names and consolidating incorrect formats helps to achieve even higher data quality.
In our solution, full names are divided into elements (prefix, first name, last name, etc.) and then each item is individually corrected according to its format rules.

Address Cleansing

During address cleaning, addresses are first converted to a uniform format, then various correcting processes are run: bugs and typing errors are corrected, defects are supplemented, abbreviations are resolved, old street names are replaced by the current one. With this service, the shortcuts and obsolescence of the address lists can be eliminated.

E-mail Cleansing

E-mail addresses stored in the database might be flawed due to recording or typing errors.
To repair e-mail addresses, both algorithmic processing and comparison with a reference database can be performed.

Verifying Identifiers

Currently our solution is optimised for Hungarian identifiers, such as personal identification documents (identity card number, passport number), other identifiers (tax identification number), business identifiers (tax number, company registration number) and bank account numbers, which can be partially verified algorithmically with the help of a reference dictionary.

Identifying and Resolving Duplicates

Using a dedicated algorithm, we find records that happen to describe the same entity: person, product, etc. We assign a duplicate identifier for each of these duplicate groups. We select the record to be retained in each duplicate group, and the rest will be eliminated. The selection of the record to be retained is made by identifying the record with highest overall data quality.
