1. 1. Visualiser and SMACK Mediator

   Master-uppsats,

   Författare :Bohua Li; [2009]
   Nyckelord :;

   Sammanfattning : With the stupendous rate of the development in network fields, more and more network based software comes into our eyesight. This thesis mainly focuses on how to build a data integration and synchronization system in order to support a distributed Web OS (Operation System) working properly with huge database on different servers.

3. 2. Zohmg—A Large Scale Data Store for Aggregated Time-series-based Data

   Master-uppsats, Chalmers tekniska högskola/Institutionen för data- och informationsteknik

   Författare :Per Andersson; Fredrik Möllerstrand; [2009]
   Nyckelord :;

   Sammanfattning : Analyzing data at a massive scale is one of the biggest challenges that Last.fmis facing. Interpreting patterns in user behaviour becomes a challenge whenmillions of users interact in billions of combinations; the data sets must beanalyzed, summarized and presented visually. LÄS MER

4. 3. Partition Aware Database Replication : A state-update transfer strategy based on PRiDe

   Magister-uppsats, Högskolan i Skövde/Institutionen för kommunikation och information

   Författare :Johan Olby; [2007]
   Nyckelord :Data Replication; Distributed Databases; PRiDe; MANET; Optimistic Replication; Real-Time Systems;

   Sammanfattning : Distributed real-time databases can be used to support data sharingfor applications in wireless ad-hoc networks. In such networks, topology changes frequently and partitions may be unpredictable and last for an unbounded period. In this thesis, the existing database replication protocol PRiDe is extended to handle such long-lasting partitions. LÄS MER

5. 4. How to Implement Multi-Master Replication in Polyhedra : Using Full Replication and Eventual Consistency

   Magister-uppsats, Högskolan i Skövde/Institutionen för kommunikation och information

   Författare :Sebastian Holmgren; [2006]
   Nyckelord :Real-Time Databases; Multi-Master Replication; Full Replication; Eventual Consistency; DeeDS; PRiDe; Polyhedra; TimesTen;

   Sammanfattning : A distributed, real-time database could be used to implement a shared whiteboard architecture used for communication between mobile nodes, in an ad-hoc network. This kind of application implies specific requirements on how the database handles replication and consistency between replicas (global consistency). LÄS MER

7. 5. Conflict Detection in DeeDS

   Magister-uppsats, Högskolan i Skövde/Institutionen för kommunikation och information

   Författare :Markus Hoffman; [2005]
   Nyckelord :optimistic replication; conflict detection; dynamic version vector; DeeDS;

   Sammanfattning : In distributed database systems, immediate global consistency of replicated data can be achieved by distributed commit protocols that are typically unpredictable. If real-time characteristics are necessary, such unpredictability has to be avoided. LÄS MER
