Consistent structural updates for object database design [chapter]

P. Poncelet, L. Lakhal
1993 Lecture Notes in Computer Science  
This paper focuses on consistent structural updates for object database design and is included in a formal approach" for advanced database modeling and design.  ...  Furthermore, the definitions of consistent updates necessary to modify and perfect IFO2 schemas are formally specified through change functions.  ...  functions to offer an incremental specification of IFO2 schemas; C3) finally, in order to design object database schema, a set of transformation rules translates an IFO2 schema into an implementable one  ...

Automatic Generation of Update Rules to Enforce Consistency Constraints in Design Databases [chapter]

James Brawner, Bonnie MacKellar, Joan Peckham, James Vorbach
1998 Data Mining and Reverse Engineering  
The database designer is provided with the flexibility of alternative semantics as a result of the two update rule types.  ...  Database systems for computer-aided design (CAD) are characterised by structural complexity and nonstandard relationship types.  ...  Here we apply EFL to the problem of updating design databases.  ...

An Approach for Designing and Implementing Eager and lazy Data Replication

Mohamed OsmanAliHegazi
2015 International Journal of Computer Applications  
The proposed approach contains two phases: In the first phase, the database is designed to have indicator fields that can carry the update status, and to consider the replication concepts by classifying  ...  being a strong belief among database designers that most existing solutions are not feasible due to their complexity, poor performance and lack of scalability.  ...  This paper presents an approach that can help the designer to design and implement a consistent replication database and make the implementation of eager and lazy updating mechanisms easier and more reliable  ...

A simple and efficient implementation of a small database

A. Birrell, M. Jones, E. Wobber
1987 ACM SIGOPS Operating Systems Review  
We believe that this is the preferred design for the class of databases we have described: moderate size (up to 10 megabytes), moderate update traffic (bursts of up to 10 update transactions per second  ...  Our design is based on technology well known to the database community -a main memory database with checkpoints and a re-do log [10, 11] .  ...

Selection of oligonucleotides for whole-genome microarrays with semi-automatic update

G. Golfier, S. Lemoine, A. van Miltenberg, A. Bendjoudi, J. Rossier, S. Le Crom, M.-C. Potier
2008 Computer applications in the biosciences : CABIOS  
Oligonucleotide microarray probes are designed to match specific transcripts present in databases that are regularly updated. As a consequence probes should be checked every new database release.  ...  We thus developed an informatics tool allowing the semi-automatic update of probe collections of long oligonucleotides and applied it to the mouse RefSeq database.  ...  Dashed lines correspond to the update of RefSeq database and solid lines to the probe design and specificity calculations.  ...

A simple and efficient implementation of a small database

A. Birrell, M. Jones, E. Wobber
1987 Proceedings of the eleventh ACM Symposium on Operating systems principles - SOSP '87  
We maintain the database as a strongly typed data structure in virtual memory, record updates incrementally on disk in a log and occasionally make a checkpoint of the entire database.  ...  This paper describes a technique for implementing the sort of small databases that frequently occur in the design of operating systems and distributed systems.  ...  We believe that this is the preferred design for the class of databases we have described: moderate size (up to 10 megabytes), moderate update traffic (bursts of up to 10 update transactions per Second  ...

Formal Framework of XML Document Schema Design

Zurinahni Zainol, Bing Wang
2012 International Journal of Information Retrieval Research  
This type of update is called update anomalies Codd (1972) . This problem occurs because of the structure design of XML document is based on the DTD in Figure 2 .  ...  As with a relational database, if we would like to update the name of the lecturer to full name "Bing Wang" in the XML document, this name needs to be updated twice.  ...

Integrated Distributed/Mobile Logistics Management [chapter]

Lars Frank, Rasmus Ulslev Pedersen
2012 Lecture Notes in Computer Science  
The objective of designing relaxed ACID properties across different database locations is that the users can trust the data they use even if the distributed database is temporarily inconsistent.  ...  This is not possible if distributed and/or mobile databases are involved and the availability of data also has to be optimized.  ...  The 1-Safe Design with Commutative Updates The 1-safe design can transfer updates to the secondary copies in the same way as the 0-safe design.  ...
