Moving and Accessing SAS Files across Operating Environments |
An alternative to traditional transport methods, CEDA eliminates the steps that have been required to move a SAS file between the native internal representations of incompatible hosts. This quick file-access feature of CEDA is one aspect of the Version 8 vision of the computing environment in which different computers share access to common files in a network system.
Supported Member Types |
CEDA supports these SAS member types:
¹ CEDA supports PROC SQL views and MDDBs for read-only access.
How CEDA Works |
If the file data representation and the accessing host data representation are the same (for example, the file is represented in Windows format and the accessing host is a Windows host), then the accessing host can read the file and write to the file.
If the file data representation and the accessing host representation are different, then the accessing host can dynamically translate the data file into the accessing host native format for read-only access. For example, an OpenVMS Alpha host can access an NFS-mounted file that is in Windows format. Using the universal header, the OpenVMS Alpha host can translate each observation that it reads into a format that it understands. The accessing host translates only the observation that it retrieves for reading.
