Concurrency Control for Transactional Drago

Jörg Kienzle

The granularity of concurrency control has a big impact on the performance of transactional systems. Concurrency control granu- larity and data granularity (data size) are usually the same. The e ect of this coupling is that if a coarse granularity is used ...

Group communications and database replication

Matthias Wiesmann

Databases are an important part of today's IT infrastructure: both companies and state institutions rely on database systems to store most of their important data. As we are more and more dependent on database systems, securing this key facility is now a p ...

Database Integration: the Key to Data Interoperability

Stefano Spaccapietra, Christine Parent

Most of new databases are no more built from scratch, but re-use existing data from several autonomous data stores. To facilitate application development, the data to be re-used should preferably be redefined as a virtual database, providing for the logica ...

The database state machine and group communication issues

Fernando Pedone

Distributed computing is reshaping the way people think about and do daily life activities. On-line ticket reservation, electronic commerce, and telebanking are examples of services that would be hardly imaginable without distributed computing. Nevertheles ...

The Database State Machine Approach

Rachid Guerraoui, André Schiper, Fernando Pedone

Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distributed transactional mechanisms, such as atomic commitment. We present the database state mac ...

Database Integration: an Overview of Issues and Approaches

Stefano Spaccapietra, Christine Parent

In many large companies the widespread usage of computers has led a number of different application-specific databases to be installed. As company structures evolve, boundaries between departments move, creating new business units. Their new applications w ...

Conceptual Modeling for Federated Geographical Information Systems over the Web

Stefano Spaccapietra, Christine Parent

A conceptual model provides the best support for federating heterogeneous datastores into a unified framework and elaborating a global consistent description of all available data. It therefore plays a central role for exchange of information within the co ...

Transaction Reordering in Replicated Databases

Rachid Guerraoui, André Schiper, Fernando Pedone

Transaction Reordering in Replicated Databases F.Pedone, R.Guerraoui and A.Schiper This paper presents a fault-tolerant lazy replication protocol that ensures 1-copy serializability at a relatively low cost. Unlike eager replication approaches, our protoco ...

The Decentralized Non-Blocking Atomic Commitment Protocol

Rachid Guerraoui, André Schiper

In a transactional system, an atomic commitment protocol ensures that for any transaction, all data managers agree on the same outcome: commit or abort. A non-blocking atomic commitment protocol enables an outcome to be decided at every correct data manage ...
