It is because DNA can be found in almost all crimes, like a bank robbery. It's left in many forms, like a hair falling off or handprints. The investigators simply run the sample through the machines, and the computer will try to find DNA matches. This way, they don't arrest the wrong person. The machine does fail, sometimes.

DNA has been called the fingerprints of today. DNA records are kept of people arrested today in most areas in the US. A Federal database is used to maintain this. In combination with DNA obtained at a crime scene, the DNA database or DNA testing of a suspect provides proof of a connection as a part of the investigation.

No, a database is a structured collection of data organized in a way that allows for efficient storage, retrieval, and manipulation of information. Data is typically stored in tables with rows and columns, making it easier to search for specific information and perform operations on the data.
No, everybody's DNA is not in the DNA database. CODIS (which is the U.S.A.'s DNA database) only contains DNA samples from individuals who have been convicted of certain crimes, individuals who have been arrested on felony charges, missing persons, and unidentified bodies. Different states have different rules for deciding who's DNA goes into the database. All fifty states take DNA samples from people convicted of major felonies, such as sexual assault and homicide. Forty-seven of the fifty states take DNA samples from everyone who has been convicted of a felony. Some states, such as California, take DNA from everyone who is arrested. Some states take DNA from everyone who has been convicted of a crime, even a misdemeanor crime.
