Rational data base standards: An examination of the 1978 CODASYL DDLC report

Eric K. Clemons
1979 Information Systems  
Unfortunately, the major design limitations associated with these earlier specifications, in particular a schema facility too closely related to machine rather than enterprise requirements and an extremely  ...  After examination of these limitations, we suggest that the recent CODASYL specifications remain inappropriate as either an instance of an ANSI/SPARC three-schema architecture or as a candidate for a national  ...  The CODASYL system is not appropriate as an instance of the ANSI/SPARC three-schema architecture. It pre-dates the *ANSI/SPARC proposal and does not successfully capture its philosophy.  ...

They are seen as being closer to the more widely accepted ANSI/X3/SPARC and co-existence data base architecture at the broad level.  ...  According to an IBM spokesman, the machine has a virtual address of 6 bytes in length. At 8 bits per byte, that equals a 48-bit address — or enough for 280 trillion bytes of virtual storage.  ... 

Simple garbage-collector-safety

Hans-J. Boehm
1996 SIGPLAN notices  
We discuss an implementation based on a preprocessor for the GNU C compiler (gcc), and give some measurements of program slowdown.  ...  We present an algorithm for annotating source or intermediate code to either check the validity of pointer arithmetic in the source, or to guarantee that under minimal, clearly defined assumptions about  ...  Rhonda Reese made an earlier version of gcc GC-safe, based on a much earlier approach. That effort convinced me that a source-level approach was interesting, at least in the short-term.  ...

A retargetable framework for instruction-set architecture simulation

Mehrdad Reshadi, Nikil Dutt, Prabhat Mishra
2006 ACM Transactions on Embedded Computing Systems  
Hence, we can incorporate any fast simulation technique in our retargetable framework without loosing performance.  ...  We illustrate the retargetability of our approach using two popular, yet different realistic architectures: the Sparc and the ARM.  ...  SimC [9] is based on a machine description in ANSI C. It uses compiled simulation and has limited retargetability.  ...

Data Structures in Natural Computing: Databases as Weak or Strong Anticipatory Systems

B. N. Rossiter
2004 AIP Conference Proceedings  
This is because of the reductionism and normalisation needed to map the structuralism of natural data on to idealised machines with von Neumann architectures consisting of fixed instructions.  ...  Classical databases store, organise and search collections of data of that real world but only as weak anticipatory information systems.  ...  Naturalised ANSI/SPARC The classical ANSI/SPARC architecture of Figure 1 has the disadvantage that the levels are not independent of each other.  ...
