Levels of the Database
DNA profiles are entered into CODIS from laboratories at the local (LDIS), state (SDIS), and national (NDIS) levels.
A local laboratory (e.g. Palm Beach Sheriff's Office Crime Laboratory) can maintain its own local database of forensic profiles and upload approved profiles to SDIS.
The state database (e.g. Florida Division of Law Enforcement-Tallahassee laboratory) will contain the forensic profiles from all the local laboratories in that state, plus the forensic profiles analyzed by the state laboratory itself. The state database will also contain the DNA profiles of convicted offenders. States may have their own regulations regarding which profile types can be maintained at SDIS. Analysts should familiarize themselves with their state requirements.
The FBI is responsible for the analysis of the convicted offender samples in the federal prison system, and entry of those profiles into CODIS. The FBI also enters DNA profiles from its forensic cases into CODIS. In this sense, it is functioning as an SDIS laboratory.
Profiles from the states (including the FBI) are uploaded into NDIS. There are specific rules that govern whether a profile can or cannot be uploaded to NDIS.03 Some categories of samples, as well as DNA profiles that do not meet minimum number of DNA loci, are not eligible for entry into NDIS. Approved analysts should familiarize themselves with the NDIS Board Procedures.
