|

|
|
<div><p>The functions performed automatically ensure that objects are processed
|
||
|
|
in a consistent, secure, and correct way. </p>
|
||
|
|
<p> These functions are: </p>
|
||
|
|
<ul><li>Object type verification. The system checks the type of object and the
|
||
|
|
type of function being performed on the object to verify that function can
|
||
|
|
be performed on that type of object. For example, if the object specified
|
||
|
|
in a CALL command is not a program, the call function cannot be performed.</li>
|
||
|
|
<li>Object authority verification. The system checks the object, the function,
|
||
|
|
and the user to verify that user can perform that function on that object.
|
||
|
|
For example, if USERA is not authorized to use OBJB in any way, he cannot
|
||
|
|
request that any functions be performed on it.</li>
|
||
|
|
<li>Object lock enforcement. The system ensures that the integrity of objects
|
||
|
|
is preserved when two or more users try to use an object at the same time.
|
||
|
|
Simultaneous changes to an object are locked out; users cannot use an object
|
||
|
|
while it is being changed.</li>
|
||
|
|
<li>Object damage detection and notification. The system monitors for errors
|
||
|
|
during the processing of objects and communicates to you unplanned failures
|
||
|
|
that result from the unrecognizable contents of objects. These failures are
|
||
|
|
communicated to you through standard messages that indicate object damage.
|
||
|
|
The system is designed so that these failures are rare, and monitoring and
|
||
|
|
communicating these failures provide integrity.</li>
