Database Schema Elicitation to Modernize Relational Databases
Legacy enterprise systems mainly consist of two kinds of artefacts: source code and databases. Typically, the maintenance of those artefacts is carried out through re-engineering processes in isolated manners. However, for a more effective maintenance of the whole system both should be analysed and evolved jointly according to ADM (Architecture-Driven Modernization) approach. Thus, the ROI and ...
متن کاملObject Database vs. Object-Relational Databases
When you don't know where you want to go, any road will take you there. Users need to understand the differences between object database management systems and the newer object relational database management systems (ORDBMSs). ORDBMSs will support some of the object extensions needed by today's more complex applications. Because of the relative size of the RDBMS vendors' marketing infrastructur...
متن کاملRelational Databases Query Optimization using Hybrid Evolutionary Algorithm
Optimizing the database queries is one of hard research problems. Exhaustive search techniques like dynamic programming is suitable for queries with a few relations, but by increasing the number of relations in query, much use of memory and processing is needed, and the use of these methods is not suitable, so we have to use random and evolutionary methods. The use of evolutionary methods, beca...
متن کاملMonitoring the Evolution of Databases in Federated Relational Database Systems
Federated Database Systems allow users to work with data stored in multiple databases by formulating queries over an integrated view. This kind of systems are of special interest for the emerging type of information systems. In this paper we present an active mechanism to keep consistency in Federated Database Systems. Event-Condition-Action rules are used as the knowledge model. First, we show...
متن کاملConverting Relational Databases into Object-relational Databases
ion (abs): A super-class is abstract (i.e., abs := true) when all of its objects are members of its sub-type objects. Instances of an abstract type cannot appear in the database extension, but are subsumed into instances of its sub-types. Attributes (Acdm): A class C has a set of attributes Acdm. Acdm := {a | a := 〈an, t, tag, l, n, d〉}, where each attribute a has a name an, data type t and a t...
