DNA hybrid typing database comparison algorithm

Abstract

The invention discloses a DNA hybrid typing database comparison algorithm. The DNA hybrid typing database comparison algorithm comprises two steps of data acquisition and data comparison, wherein thedata acquisition comprises the steps of: S101: receiving various types of data sources, including case data, manual input data and CODIS file data of a laboratory management system are extracted in aninterface mode; and S102:designing a standard Oracle data model based on a DNA hybrid typing database in a data acquisition process, uniformly converting data of different data sources into the standard data model, and establishing a standard data basis for data comparison, wherein the data comparison process is started in a manner of combining a comparison queue with a thread pool. Through the functions of standardized storage, automatic splitting, intelligent analysis, rapid comparison and the like of DNA hybrid sample parting information, existing hybrid samples are fully utilized, experimenters can be reminded of successful comparison in time after successful comparison, more clues are provided for case detection, and rapid case detection is assisted.

Description

technical field [0001] The invention relates to the technical field of DNA databases, in particular to a comparison algorithm for DNA mixed typing databases. Background technique [0002] With the rapid development of criminal investigation technology, the accuracy of DNA detection technology is increasing day by day, and the role of DNA in court evidence is getting more and more attention. However, in daily work, it is not uncommon for physical evidence to detect mixed results. No separate database was established for mixed-type DNA typing, and such samples could not be used as evidence. [0003] The environment of the crime scene is complex, and it is not easy to extract a single DNA sample. At the same time, due to the pollution caused by the extraction personnel and the improvement of the sensitivity of the reagents, more and more mixed samples appear in the forensic inspection work. How can the existing The use of mixed samples and the splitting of mixed samples have b...

[0002] With the rapid development of criminal investigation technology, the accuracy of DNA detection technology is increasing day by day, and the role of DNA in court evidence is getting more and more attention. However, in daily work, it is not uncommon for physical evidence to detect mixed results. There is no separate database for pooled DNA typing and such samples cannot be used as evidence

[0003] The environment of the crime scene is complex, and it is not easy to extract a single DNA sample. At the same time, due to the pollution caused by the extraction personnel and the improvement of the sensitivity of the reagents, more and more mixed samples appear in the forensic inspection work. How can the existing The use of mixed samples and the splitting of mixed samples have become a major problem in forensic work

[0004] Therefore, a set of solutions for splitting and analyzing DNA mixed typing is needed to solve practical problems such as difficult analysis of mixed DNA samples, single information, and low utilization rate of clues, so as to achieve faster and more accurate analysis of cases

[0005] Disadvantages of the existing structural principle: the structural principle is relatively simple, single

[0006] The disadvantages of the existing technology: the existing technology still has the problems of unstable comparison, long comparison time, large amount of manual labor, and low efficiency
