Appeal No. 2000-0240
Application No. 08/285,534
We agree with appellants that the address mapping of Weinreb would not, in our opinion,
have a grouping of a plurality of physical databases into a logical database. The examiner
assertion at page 2 of the final rejection states:
i. In response to Applicant's repeated assertions in the Appeal Brief
that "logical addressing has nothing whatsoever to do with grouping a
plurality of physical databases to form a logical database defined by logical
database information," Examiner notes that Weinreb et al. clearly provide for
"virtual memory mapping ... in an object-oriented database system having
permanent storage for storing data in at least one database, ... and a
processing unit which runs application programs which request data using
virtual addresses (see the abstract). As further defined by Weinreb et al.,
such virtual addresses are translated into a physical address of the plurality
of databases, by using tables that correlate each virtual addresses to a
respective database, and segments, offsets and lengths of data objects
within that database (see Figs. 5-8 and 15-19). Weinreb et al. further clearly
assert such use of virtual addressing as a manner to "name objects using
the format of the computer hardware. More particularly, it is an object to
provide virtual addresses as pointers to objects in the database" (see col. 2,
lines 5-11).
ii. Applicant's assertion in the Appeal Brief that "In Weinreb, address
mapping depends on pointers, while the present invention as recited in claim
39 does not depend on pointers" (page 15 of the Appeal Brief) is not
persuasive, since the claims do not distinguish from the use of pointers. The
instant claim language, "table location searching means ... for searching for
a table stored in at least one of said physical databases based on said
logical database information, ..." (claim 39) "reads-on" the use of the
persistent relocation map and virtual address relocation map of Weinreb et
al. to locate data in one of the plurality of physical databases, in response to
an application program's request for data, using a virtual address as the
logical identifier of the data.
