A Referential Integrity Browser for Distributed Databases
We demonstrate a program that can inspect a distributed relational database on the Internet to discover and quantify referential integrity issues for integration purposes. The program computes data quality metrics for referential integrity at four granularity levels: database, table, column and value, going from a global to a detailed view, exhibiting specific evidence about referential errors....
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 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...
متن کاملMetaprogramming for Relational Databases
For systems that share enough structural and functional commonalities, reuse in schema development and data manipulation can be achieved by defining problem-oriented languages. Such languages are often called domainspecific, because they introduce powerful abstractions meaningful only within the domain of observed systems. In order to use domain-specific languages for database applications, a m...
متن کاملA Relational Algebra for Negative Databases
A negative database is a representation of all elements not contained in a given database. A negative database can enhance the privacy of sensitive information without resorting to encryption. This can be useful in settings where encryption is too expensive, e.g., some sensor networks, or for applications where searches or other operations on stored data are desired. The original negative datab...
