Attributes can be data, user, session or tools based to deliver the greatest level of flexibility in dynamically granting/denying access to a specific data element. On big data , and distributed file systems such as Hadoop, ABAC applied at the data layer control access to folder, sub-folder, file, sub-file and other granular.
After a data submission is received and updated, a confirmation e-mail will be sent to the pharmacy contact which will confirm the date processed, the number of records received, the number of records with errors and the name of the submitted file.

A compiled version of an Access database (file extensions .MDE /ACCDE or .ADE; ACCDE only works with Access 2007 or later) can be created to prevent users from accessing the design surfaces to modify module code, forms, and reports. An MDE or ADE file is a Microsoft Access database file with all modules compiled and all editable source code ...

ALFA supports all the data types that are defined in the OASIS XACML Core Specification. Some datatypes e.g. numerical (integer, double) and boolean map directly from ALFA to XACML. Others need to be converted such as date or time attributes. To convert an attribute into the relevant data type, use the "value":datatype notation. See below for ...
In computer systems security, Relationship-based access control (ReBAC) defines an authorization paradigm where a subject's permission to access a resource is defined by the presence of relationships between those subjects and resources. In general, authorization in ReBAC is performed by traversing the directed graph of relationships.
This enables party-to-party sharing and fine-grained delegation of access authorization. A resource owner need not consent to token issuance at runtime (i.e. each time their data is requested), but can instead define a policy at the authorization server to allow requesting parties asynchronous access to specific limited authorization scopes.
A filesystem ACL is a data structure (usually a table) containing entries that specify individual user or group rights to specific system objects such as programs, processes, or files. These entries are known as access-control entries (ACEs) in the Microsoft Windows NT , [ 4 ] OpenVMS , and Unix-like operating systems such as Linux , macOS ...
