How to define database structure and insert some initial objects from scratch

Hi from Spain! We're evaluating ObjectDB and we have some questions: - How can we create the initial database structure of our application? We know objectdb is all about objects and probably not need initial structure like tables, but how can we populate some "tables" with initial data from a script? In SQL world we have scripts like "insert into..." - Can we use main objectdb.jar library as jdbc driver for ETL software like Kettle? How about migrating data from another database system? #1 2012-02-23 19:18 Hi from Spain! We're evaluating ObjectDB and we have some questions: - How can we create the ...
