الملخص الإنجليزي

In real life, there are lots of relational database systems which the user, when using them, faces problems related to missing values, whether these values are unknown to the user or are non-existentwhich lead to statistics and reports retrieved from these systems not being representative of the original stored data.

For these reasons many researchers tried to do the relational database estimation of missing values with a high estimated accuracy rate.

The present treatment is through estimating and replacing the missing values with approximate values obtained from the development of an algorithm that combines the two algorithms of data mining for estimations and predictions.

The treatment also checks and validates the stored and estimated values through comparing them with the business rules.

The two algorithms used in the treatment are: • Decision Trees algorithm.

• K-nearest neighbor algorithm after amendment through this research work.

Theimplementation of thepresent treatment shows treatment validity with a success rate of up to 80%.
