`Huge advantages..' in associative model of data.... Bloor Research. (Database News).In a report, Bloor Research investigates the differences between the associative as·so·ci·a·tive adj. 1. Of, characterized by, resulting from, or causing association. 2. Mathematics Independent of the grouping of elements. and relational models See relational database. relational model - relational data model of data and stresses the power of the data and metadata are stored side-by-side. Bloor states: `The effect of this different approach to metadata is significant. In particular it means that you can write programs that read metadata directly as part of the program. If an application can do this, then it can run against any schema and you can change the database's metadata without affecting the suitability of the application. By contrast, with an application built against a relational database relational database Database in which all data are represented in tabular form. The description of a particular entity is provided by the set of its attribute values, stored as one row or record of the table, called a tuple. , you have to change the program Whenever the database changes. The associative model potentially offers huge advantages when it comes to both application reuse reuse - Using code developed for one application program in another application. Traditionally achieved using program libraries. Object-oriented programming offers reusability of code via its techniques of inheritance and genericity. and application maintenance.' www.lazysoft.com |
