What type of information do commercial databases typically provide?

Commercial databases primarily provide access to public records and court information. This includes a wide array of documents such as property records, marriage and divorce records, criminal records, and other public filings that can be useful for various purposes, including background checks, legal research, and verifying identities. These databases compile information from government sources and make it accessible to individuals and organizations for legitimate uses, often with the aim of providing transparency and aiding in decision-making processes.

The other types of information listed, such as military service records, medical records, and psychological evaluations, are typically protected by laws and regulations that restrict access to personal and sensitive information. Such records are not available in commercial databases due to privacy concerns and the need to maintain confidentiality for individuals. Therefore, those alternatives do not fit within the standard types of information you would expect to find in commercial databases.
