With z/TPF support for MongoDB, when accessing a document (or z/TPFDF subfile), either all the data within that subfile is exposed to the end user or none of it. There are mechanisms as part of z/TPF user security that can prevent an end user from seeing a MongoDB collection (or z/TPFDF file), however, there is no mechanism for an end user to see a subset of the data in a MongoDB collection. This becomes an important concept as some customers have z/TPFDF files that can contain a mix of end-user information. Opening this z/TPFDF file for... [More]
