Do you have an impedance mismatch problem? Users speak up!

I have started a new series of interviews with users of technologies for storing and handling persistent objects, around the globe.

Here I define “users” in a very broad sense, including: CTOs, Technical Directors, Software Architects, Consultants, Developers, Researchers.

I have asked 5 questions:

Q1. Please explain briefly what are your application domains and your role in the enterprise.

Q2. When the data models used to persistently store data (whether file systems or database management systems) and the data models used to write programs against the data (C++, Smalltalk, Visual Basic, Java, C#) are different, this is referred to as the “impedance mismatch” problem. Do you have an “impedance mismatch” problem?

Q3. What solution(s) do you use for storing and managing persistence objects? What experience do you have in using the various options available for persistence for new projects? What are the lessons learned in using such solution(s)?

Q4. Do you believe that Object Database systems are a suitable solution to the “object persistence” problem? If yes why? If not, why?

Q5. What would you wish as new research/development in the area of Object Persistence in the next 12-24 months?

The first series of interviews I published in ODBMS.ORG include:
