an object-relational application is one in which a program written using an object-oriented language uses a relational database for storage and retrieval. A programmer must address one or more problems of an object-relational impedance mismatch during the production of an object-relational application...
Here impedance mismatch refers to clarity and performance difficulties that arise because of the nature of the embedding. Because of the central position in the information technology industry of object-oriented programs that access SQL-based relational database systems, reducing impedance mismatch is ...

Object relational mapping refers to the process of mapping your relational data model to your object model. Object Spaces is a highly publicized framework for doing just that. The mismatch I refer to is a result of the differences in structure between a normalized relational database and a typic...
In other words, the reflection coefficient S11 that is present at the directional coupler output may be the ratio of the vector amplitude, or electric field strength, of the reflected wave, which was caused by an impedance mismatch that is present on the transmission line, to the amplitude of...
functioning of the device 2 is the provision of a common mode rejection, since a large electromagnetic interference exists through the living being 6 being examined. Also, AC interference caused by the power supply network can cause large disturbances. Furthermore, there must be a mismatch of ...
It occurs in various aspects of database application programming. There are three concerns judged the most important: mismatching data models, mismatching binding times and mismatching object lifecycle. This paper focuses on the data model mismatch. We introduce the common state theory, i.e. a ...
The phrase "impedance mismatch" is often used to characterize the difficulties in sharing data between the relational and object-oriented models. By harnessing the power of modern Relational Database Management Systems (RDBMS), an easy-to-implement, easy-to-use, persistent storage solution for Java...
Eliminating the Impedance Mismatch Between Relational and Object-Oriented SystemsRelational database management systems (RDMSs) and their extensions have been widely used in industry for many years. Although there has been much research done for developing the object-oriented database systems recently, ...
