The paper issues a technique for constructing effective data insertion procedures in structure-independent databases that uses the activity approach. The essence of this technique is to present the procedure in the form of an action mechanism that allows its semantics to be opened, thereby minimizing the number of identical same meaning characteristics. The use of the technique for data insertion procedures constructing into structure-independent databases, as well as the use of a NoSQL DBMS that is homogeneous in structure to structure-independent databases made it possible to significantly improve performance. You can judge it from the computational experiment which is performed in the work.
