The objective of this paper is to present a method to insert, edit, and delete database records without affecting the sequence of existing data. Typically, databases comprise integer data fields, in this paper named sequence number, meant to determine the user-defined sequence of data records. Inserting new data records or editing the sequence number of data records might cause a resequencing of the existing data records. This resequencing can be avoided by using a numbering system that decreases the value of a number when a digit is added to its end. Such a numbering system allows to insert an infinite quantity of additional sequence numbers between two sequence numbers even if their difference is 1.
