MemberDescription
DBMS Database user authentication (a database user name and password required).
OSA Operating system authentication (No user name or password need be provided, they are taken from the OS).
Example
Opening an Enterprise Geodatabase using connection properties
public async Task OpenEnterpriseGeodatabase()
{
    await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
    {
        // Opening a Non-Versioned SQL Server instance.
        DatabaseConnectionProperties connectionProperties = new DatabaseConnectionProperties(EnterpriseDatabaseType.SQLServer)
        {
            AuthenticationMode = AuthenticationMode.DBMS,

            // Where testMachine is the machine where the instance is running and testInstance is the name of the SqlServer instance.
            Instance = @"testMachine\testInstance",

            // Provided that a database called LocalGovernment has been created on the testInstance and geodatabase has been enabled on the database.
            Database = "LocalGovernment",

            // Provided that a login called gdb has been created and corresponding schema has been created with the required permissions.
            User = "gdb",
            Password = "password",
            Version = "dbo.DEFAULT"
        };

        using (Geodatabase geodatabase = new Geodatabase(connectionProperties))
        {
            // Use the geodatabase
        }
    });
}
Create Default QueryDescription for a Database table and obtain the ArcGIS.Core.Data.Table for the QueryDescription
public async Task DefaultQueryDescription()
{
    await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
    {
        DatabaseConnectionProperties databaseConnectionProperties = new DatabaseConnectionProperties(EnterpriseDatabaseType.SQLServer)
        {
            AuthenticationMode = AuthenticationMode.DBMS,
            Instance = "instance",
            Database = "database",
            User = "user",
            Password = "password"
        };

        using (Database database = new Database(databaseConnectionProperties))
        {
            QueryDescription queryDescription = database.GetQueryDescription("CUSTOMERS");

            using (Table table = database.OpenTable(queryDescription))
            {
                //use table
            }
        }
    });
