FIELD: information technology.
SUBSTANCE: invention relates to the field of information technology, namely, methods of organizing and / or finding data in database systems, and can be used in data processing systems. In the data integrity assurance method, the data from the raw data fields in the raw data record is converted to a vector from numerical values. Specify a formal description of the components of the generated vector and the vector components from the cleaned database, while in the formalized description indicate the logical consistency conditions that determine the correctness of the contents of the components of these vectors. After that check the feasibility of the specified logical conditions, if the above logical conditions are satisfied, the vector is compared with the remaining vectors from the cleaned database and, if there is a mismatch, the vector representation of the raw data record is added to the cleared database.
EFFECT: increasing the integrity of data stored in database systems by identifying and eliminating erroneous, distorted, inaccurate data, as well as data that contradict themselves or previously entered data.
