National DNA Database has attracted a good deal of public attention in the last eight years. The practical application of DNA technology to identify biologically criminals has also draw controversy for human privacy among the antagonists of the system. However, DNA database had a significant impact on forensic biology, because it enables much stronger conclusions of identity or non-identity to be established. Databases of DNA profiles are being compiled as an aid to criminal intelligence using powerful incriminating evidence. Some defendants in court are often persuaded to change their plea or else mount a tough legal challenge to the DNA evidence that will be presented during court trial. DNA profiling is a technique by which an individual can be identified at molecular level. The use of DNA evidence in criminal investigation has grown in recent years. DNA databases in many countries have helped law enforcement units identify criminals and solve difficult crime such as rape, robberies, mysterious murders and etc. The  DNA database has potentials to safeguarding national security improvements especially in the immigration system, home affairs too and general access control systems. National DNA Database has a power for rapid identification for the postmortem and those who involved in a mass-disaster (naturally or man- made such as explosions).  Using DNA typing is one of good advantages possible to identify human remains that decomposed or burned beyond recognition. A computerized Biometric database that designed special for the population identification and ear-marking of serious criminal offenders have already riping huge benefits in the countries that possessing them. Short Brief How DNA Match Works A DNA database allows swift analysis for a criminal investigations and encouraging highly sophisticated scientific equipment deployment: In order to establish a match, the first step is to create genetic profiles in the database center that then link evidence from multiple crime scenes or to an offender who has donated a DNA sample to a database.  The profile is generated from genetic material taken from the suspect or scene of crime and loaded into a lab sequencing machines after it disassembled into segments to isolate loci, size-height and measuring them. Then the suspect's DNA profile is compared with sample of physical evidence to see whether they will produce an exactly match. If a conclusive non-match occurs, the suspect may be eliminated from consideration. If a match occurs, a further statistical analysis is performed to determine the probability that the sample of physical evidence came from another person with the same DNA profile as the suspect's. Juries use this statistical result in determining whether a suspect is guilty or innocent Interpreting Results of DNA Analysis in Criminal Investigation 1. Inclusion:  When the DNA profile of a known individual (A victim or suspect) matches the DNA profile from the crime scene evidence, the individual is “included” as a potential source of that evidence. 2. Exclusion:  When the DNA profile from an individual (A victim or suspect) does not match the DNA profile generated from the crime scene evidence, the referenced individual is “excluded” as the donor of the evidence. 3. Inconclusive:  Inconclusive results indicate that DNA testing did not produce information that would allow an individual to be either included or excluded contrast to source of the biological evidence.
National DNA database is a system that regulated and maintained by the government for storing DNA profiles of its population.  This particular database can be used in medical analysis of genetic based diseases,therapies, forensic criminology, human identification or genealogical studies that soon or later this special sector can be utilized by Ministry of Home Affairs to tap into a vast repository that contains biological IDs of every citizens. DNA databases can be public or private, but normally the largest ones are national DNA databases owned by the states. There are various databases like forensic databases,medical databases,veterinary databases (RhODIS)  and genomic databases. If you link them together they will create an unique entity that have branches,laboratories,nodules and single interface distributed at regional,local,national and as well as forging official ties with other international groups, e.g World Genbank, Interpol and other various nations who signed a bilateral ratifications to combat cross borders crimes and curb human trafficking syndicates,mafia and  terrorism networks. 
Today, over 60 countries worldwide operating national DNA databases, includes some African nations example Botswana, South Africa and plus Tanzania that planing to  establish their own center. The DNA database at Interpol is commonly used in helping criminal investigations throughout the world. Interpol maintains an automated submit-search-portal called DNA Gateway that contains DNA profiles submitted by member countries from crime scenes, missing persons,unidentified bodies, fugitives and so forth. This DNA Gateway portal was established in 2002, and at the end of 2013, it had more than 140,000 DNA profiles from 69 member countries of which Namibia is included on the list. Unlike other DNA databases, DNA Gateway at  Interpol is only used for information sharing and comparison, it does not link a DNA profile to any crime free person or by tagging physical or psychological conditions of an individual.             Kuwait The Kuwaiti government passed a law in July 2015 requiring all citizens and permanent residents to be enrolled into the system. The population of Kuwait is (about 4.2 million people) whom all their DNA samples are taken for a national database. The system is also fed with genetic information from visiting tourists who surrender DNA samples before entering Kuwaiti. The reason for this comprehensive law was drafted after the serious security concerns posed by the suicide bombing  of the Imam Sadiq mosque. The first phase of the campaign has now finished generating enough DNA profiles in September 2016, which other nations recommended that it was an optimistic move in securing influx of immigrations, combat global terrorism and fraud identity.

In 2012, Brazil approved a national law establishing DNA databases at state and national levels for DNA profiles of individuals convicted of violent crimes. Following the decree of the Presidency of the Republic of Brazil in 2013, which regulates the 2012’ forensic  law, Brazil began using CODIS in addition to the DNA database’s evidence for solve crimes. [ more ]             South Africa The new DNA Act # 37 of 2013 in Republic of South African has made a provision for all prisoners to give DNA samples to the national database in regardless what types of offenses they primarily committed. This is a decisive measure taken from new DNA law, to compel every inmates for sample testing for the purpose to mitigate repeatedly offenses and identify people who may turn to be crime habitiviors and mark those serious serial offenders.[ more ]
