i want to carry out a project in crime forensics. this will help as a medium to my country adapting to the molecular method of dealing with crime cases
My opinion is that the database is the consequence of crime forensic activities, at least, at the beginning.
For each case to resolve, police officers will propose a list of suspects (based on evidence, agenda, alibis, etc), and their DNA will be analyzed = comparison with DNA found on evidences (weapons, sperm stains, ...). If there is a serious match, the suspect will be arrested.
The DNA collected during the case will be integrated in the database for later uses = to resolve a crime committed in the same time, or place, or with great similarities.
In France, we have an "Automated database for genetic prints" : every DNA sample collected on evidences, and DNA of every person suspected (not arrested) in a crime are collected in the database.

It may be prudent to consider the financial feasibility and responsibility of such a project. While many crimes are tragic, the cost of solving those crimes cannot be ignored. Any such genetic databasing and crime solving initiative would need to be publicly funded, which would likely be funded by taxes and other government revenue - which could also be spent on other priorities. If those other priorities would better improve the public good, then the decision to invest them in a genetic databasing and crime solving initiative would be poorly spent.
Do recall that many crimes cannot be solved by genetic evidence alone, or they can be solved regardless of the existence of genetic evidence.
There are additional civil rights concerns related to a government engaging in widespread and coerced collection of evidence for use against it's own civilian population. Unless you have the utmost faith that the governments that would control such a database and program will be forever benign, it may be prudent not to encourage the creation of such a system.
Rawanda beat you to it, Sulley, and the complaints are already getting started: https://www.independent.co.uk/news/world/africa/rwanda-dna-database-human-rights-privacy-a8832051.html
