Specification and Refinement of Databases and Transactions
1993The development process of data-intensive information systems passes through several stages from requirements modeling through conceptual design down to implementation. In DAIDA we used the language TDL for design specification and DBPL, a procedural database programming language with persistent values and transactions, for implementation.

The complexity of satisfying constraints on databases of transactions [PDF]
Acta Informatica, 2007 Computing frequent itemsets is one of the most prominent problems in data mining. Recently, a new related problem, called FREQSAT, was introduced and studied: given some itemset–interval pairs, does there exist a database such that for every pair, the frequency of the itemset falls in the interval?

Transaction management in design databases
2005Databases are being increasing applied to support design and engineering, implemented on a backend file server and supporting shared access. A fundamental difference between traditional database management and design database management is that for most of the design process, integrity is partial.

Transaction Processing in Broadcast Databases
2011Broadcasting is a popular way of disseminating data due to the scalability of its request performance with an increasing population, and its ability to “match” the unique characteristics of modern wireless communications. The necessary decoupling of the clients from the server in the broadcast architecture, however, complicates database-style ...

Transaction Management and Database Resources
1998Evidence has been provided in the preceding chapter that the best way to approach transaction management is to look at the dual challenge of dataflows and processes, each on its own merits. The careful transaction system designer will also examine the prevailing circumstances characterizing an implementation, and try to treat constraints and enabling ...

A model of concurrent database transactions
22nd Annual Symposium on Foundations of Computer Science (sfcs 1981), 1981When several transactions (processes) read and write items in a database, the question of consistency of the database arises. Consistency is maintained if transactions are serial: all actions of a transaction execute completely before the actions of the next transaction begin.

The deductive synthesis of database transactions
ACM Transactions on Database Systems, 1993Database programming requires knowledge of database semantics both to maintain database integrity and to explore more optimization opportunities. Automated programming of database transactions is desirable and feasible. In general, transactions use simple constructs and algorithms; specifications of database semantics are available; and transactions ...

An axiom system for database transactions
Information Processing Letters, 1990Abstract A class of transactions is defined that expresses exactly first-order definable database updates. A complete Hoare axiom system is developed for the reasoning of transactions. The system has applications in the verification, optimization, and synthesis of database programs.

Translating object-oriented database transactions into relational transactions
Information and Software Technology, 2002Abstract In this paper, we present methods of translating transactions from object-oriented database (OODB) to relational database (RDB). The process involves schema mapping in data definition language and transaction translation in data manipulation language. They include scheme definition, data query and transaction operation of insert, update, and

Transactional Support for Mobile Databases
2005With the widespread deployment of wireless communication infrastructure in the past decade, accessing information online while a client is on the move becomes a concrete possibility. Such a computing environment is often referred to as a mobile environment (Imielinski & Badrinath, 1994).
