We provide mechanisms that facilitate database design based on a shrink wrap schema. A shrink wrap schema is a well-crafted, complete, global schema that represents an application. We develop the notion of concept schemas as a way to decompose shrink wrap schemas. A concept schema is a subset of an application schema that addresses one particular point of view in an application. To aid in shrin...

The aim of the present article is to probe the functions of the cultural schema of Ta’ne (sarcasm) in Persian. Results from 100 recorded instantiations of Ta’ne accumulated through ethnographic approach indicated that it served different functions including complaint, criticism, insult, contempt, humor, and compliment. The results were then discussed with reference to the cultural differences i...

Schema matching is the problem of finding relationships among concepts across heterogeneous data sources that are heterogeneous in format and in structure. Starting from the “hidden meaning” associated with schema labels (i.e. class/attribute names) it is possible to discover relationships among the elements of different schemata. Lexical annotation (i.e. annotation w.r.t. a thesaurus/lexical r...

You can create source models from your relational source schema data of your metadata to be required in order to convert datatypes or to interpret your metadata. As with Designer's JDBC, Salesforce and WSDL importers, the XML File. Editing and validation support for XML Schema, Relax NG, NVDL scripts, Browse, edit, or query using XQuery and SQL with native XML or relational oXygen includes a to...

Generating Web site schema is a core step for value-added services on the web such as comparative shopping and information integration systems. Several approaches have been developed to detect this schema. For a real web site, due to the complexity of the site schema, post process of this schema such as labeling the schema types, comparing among different schema types and generating an extracto...

Schema evolution is the process of applying changes to a schema in a consistent way and propagating these changes to the instances while the database is in operation. However, when a database is shared by many users, updates to the database schema are always difficult. To overcome this problem, in this paper we propose a version mechanism for schema evolution in ODMG databases that preserves ol...

Modern information systems may exploit numerous XML formats for communication. Each message may have its own XML format for data representation which causes problems with integration and evolution of their schemas. Manual integration and management of evolution of the XML formats may be very hard. We tackled this problem in our previous work, however, for simplicity reasons, we omitted the poss...
