Generally, a genealogical DNA test might use either autosomal STRs or autosomal SNPs. (STR's are Short Tandem Repeats; SNPs are single-nucleotide polymorphisms.) However, testing companies do not currently offer autosomal STRs tests that use enough STR markers for genealogy.
The schema is the Active Directory component that defines all the objects and attributes that the directory service uses to store data. The physical structure of the schema consists of the object definitions. The schema itself is stored in the directory.
Active Directory is a special-purpose database â it is not a registry replacement. The directory is designed to handle a large number of read and search operations and a significantly smaller number of changes and updates.Active Directory data is hierarchical, replicated, and extensible.Because it is replicated, you do not want to store dynamic data, such as corporate stock prices or CPU performance. If your data is machine-specific, store the data in the registry.ou may be wondering what objects are currently stored in Active Directory. Active Directory has three partitions. These are also known as naming contexts: domain, schema, and configuration. The domain partition contains users, groups, contacts, computers, organizational units, and many other object types.
