Efficient Schemes To Evaluate Transaction Performance In Distributed Database Systems, R. Mukkamala, S. C. Bruell
Efficient Schemes To Evaluate Transaction Performance In Distributed Database Systems, R. Mukkamala, S. C. Bruell
Computer Science Faculty Publications
Database designers and researchers often need efficient schemes to evaluate transaction performance. In this paper, we chose two important performance measures: the average number of nodes accessed and the average number of data items accessed per node by a transaction in a distributed database system. We derive analytical expressions to evaluate these metrics. For general applicability, we consider partially replicated distributed database systems. Our first set of analytic results are closed-form expressions for these two measures. These are based on some fairly restrictive simplifying assumptions. When these assumptions are relaxed, no closed-form expressions exist for these averages. Hence, we develop …
Performance Analysis Of A Distributed File System, Meenakshi Mukhopadhyay
Performance Analysis Of A Distributed File System, Meenakshi Mukhopadhyay
Dissertations and Theses
An important design goal of a distributed file system, a component of many distributed systems, is to provide UNIX file access semantics, e.g., the result of any write system call is visible by all processes as soon as the call completes. In a distributed environment, these semantics are difficult to implement because processes on different machines do not share kernel cache and data structures. Strong data consistency guarantees may be provided only at the expense of performance.
This work investigates the time costs paid by AFS 3.0, which uses a callback mechanism to provide consistency guarantees, and those paid by …
Attribute Relationships: An Impediment In Automating Schema Integration, Amit P. Sheth, Sunit K. Gala
Attribute Relationships: An Impediment In Automating Schema Integration, Amit P. Sheth, Sunit K. Gala
Kno.e.sis Publications
Success in schema integration depends on understanding the semantics of schema components (e.g., entity sets, relationship sets, attributes), and the ability to capture and reason about these semantics. An important objective of our work on schema integration is to automate the reasoning as much as possible, and when not possible, depend on the human input and guidance. A key results of comparing the semantics associated with schema objects is that of determining attribute relationship. Once attribute relationships are determined, the task of object class(e.g., entity sets and relationship sets) integration becomes simpler and can e automated to a great extent. …
Data Base Design For Research In Comparative Zapotec, Anita C. Bickford
Data Base Design For Research In Comparative Zapotec, Anita C. Bickford
Theses and Dissertations
This thesis explores the nature and content of a comparative data base for the Zapotec languages of Mexico that may be produced. Many questions are discussed: how to sub-divide and list the Zapotec languages and dialects; what data format will be most accessible to researchers as well as to field workers with data to add; computer software considerations (designing computational tools); how to handle non-cognates with shared meanings, non-overlap of glosses (i.e., one Zapotec gloss covers several Spanish words, or vice versa), semantic shifts and secondary meanings, and other problems such as special characters, free variation, elisions, etc.; whether to …

Fault Tolerance In A Very Large Database System: A Strawman Analysis, Amit P. Sheth
Fault Tolerance In A Very Large Database System: A Strawman Analysis, Amit P. Sheth
Kno.e.sis Publications
A simple model is used to study the effect of fault-tolerance techniques and system design on system availability. A generic multiprocessor architecture is used that can be configured in different ways to study the effect of system architectures. Important parameters studied are different system architectures and hardware fault-tolerance techniques, mean time to failure of basic components, database size and distribution, interconnect capacity, etc. Quantitative analysis compares the relative effect of different parameter values. Results show that the effect of different parameter values on system availability can be very significant. System architecture, use of hardware fault tolerance (particularly mirroring), and data …
Enhancing Manufacturing Planning And Control Systems Through Artificial Intelligence Techniques, Ronald S. Dattero, John J. Kanet, Edna M. White
Enhancing Manufacturing Planning And Control Systems Through Artificial Intelligence Techniques, Ronald S. Dattero, John J. Kanet, Edna M. White
MIS/OM/DS Faculty Publications
Manufacturing planning and control systems are currently dominated by systems based upon Material Requirements Planning (MRP). MRP systems have a number of fundamental flaws. A potential alternative to MRP systems is suggested after research into the economic batch scheduling problem.
Based on the ideas of economic batch scheduling, and enhanced through artificial intelligence techniques, an alternative approach to manufacturing planning and control is developed. A framework for future research on this alternative to MRP is presented.

The Computer As A Collection Management Tool, Suzanne B. Mclaren, Hugh H. Genoways, Duane A. Schlitter
The Computer As A Collection Management Tool, Suzanne B. Mclaren, Hugh H. Genoways, Duane A. Schlitter
University of Nebraska State Museum: Mammalogy Papers
Since the mid-1960s, discussion of computer use for information retrieval in museum collections has usually focused on research potential. Much attention has been given to the idea of networking and the ability to access data across great distances. However, the potential for collection management usage has also proven to be a legitimate rationale for computerization. Numerous aspects of collection management are discussed for which the computer may be employed. Topics include creating cross-reference files, updating taxonomic and geographic information, pinpointing mismatched specimens, locating lost and uncataloged material, controlling loan procedures, producing accession files for insurance purposes, curating all or part …

An Analysis Of The Effect Of Network Load And Topology On The Performance Of Concurrency Control Algorithm In Distributed Database Systems, Anoop Singhal, Amit P. Sheth, Ming T. Liu
An Analysis Of The Effect Of Network Load And Topology On The Performance Of Concurrency Control Algorithm In Distributed Database Systems, Anoop Singhal, Amit P. Sheth, Ming T. Liu
Kno.e.sis Publications
Earlier studies in the performance analysis of concurrency control algorithms in distributed database systems (DDBS) have assumed that the message transmission time between any two nodes of a network is constant. Hence they disregard the effect of communication subnet related parameters such as network traffic, network topology, the capacity of transmission channels and the size of messages transmitted. In this paper an analytical model is used to estimate the delays in transmission channels for a DDBS in a long haul network. The analysis shows that the constant transmission time assumption cannot be justified in many cases and that response time …

Decide : How Much Superphosphate, G A. Robertson, J. W. Bowden, N. J. Halse
Journal of the Department of Agriculture, Western Australia, Series 4
* A 400 per cent increase in ihe price of superphosphate has reduced the economic optimum rates of super for crops and pastures in 1975.
* Many factors, both biological and economic, must be taken into account in determining the rate of superphosphate to apply.
• DECIDE, a model developed by CSIRO and the Department of Agriculture, provides a formal system in which all these factors can be considered.
• DECIDE is based on the results of all research on superphosphate carried out in Western Australia. However, each farmer's own knowledge of his farm, the soils, crops and animals is …
A Geo-Marine Informational System For Coastal Zone Management, Stella Maris A. Vallejo
A Geo-Marine Informational System For Coastal Zone Management, Stella Maris A. Vallejo
Marine Affairs Theses and Major Papers
The purpose of this paper is to present a system analysis for the evaluation and interpretation of information on coastal zone management. We understand by system analysis the consideration of a complex made by related parts, and not merely a totally of parts, where the significance of one thing depends on its relationship with the others. Based on this criteria of interconnections between phenomena, we assume, we are going to give the coastal zone a treatment of a system and in this way impose a correlative statement to the information related to this area. This system approach for the information …

Grade Herd Recording, 1963-64, Maurice C. Cullity
Grade Herd Recording, 1963-64, Maurice C. Cullity
Journal of the Department of Agriculture, Western Australia, Series 4
A review of Grade Herd Recording during the 1963-64 season.
THERE was a substantial increase in the number of cows which were recorded in 1963-64 compared with 1962-63 (23,520 and 22,635 respectively).
This season's figure represents 20.4 per cent, of all cows in the dairying districts.
The number of cows which completed lactation and therefore whose yields were included in the averages, rose from 17,258 to 19,011.
