NHibernate – Generate classes from a database

nhibernateorm

I know that you can generate a database from classes and their mappings using nHibernate, but I can't find any good links to do this the other way around. We have a database that has already been designed, and we are looking at using nHibernate. It would be nice to use a tool to generate the mappings and classes from the database, and then we could tweak/manipulate them to suit our tastes.

R – ORMs that generate database structures from classes

This is something that NHibernate does.

And on the subject (that Draemon) started. My personal view is that unless performance is your absolute 1st priority and all other things must suffer to make that happen (e.g. when writing software for a manufacturing fab), you will be better off working on the domain model first.

My reasoning: you spend a lot more time coding against the domain than you do against the database itself -- especially when using an orm. So spend that time wisely.

MySQL – force not to use cache for testing speed of query

Try using the SQL_NO_CACHE (MySQL 5.7) option in your query. (MySQL 5.6 users click HERE )

eg.

SELECT SQL_NO_CACHE * FROM TABLE

This will stop MySQL caching the results, however be aware that other OS and disk caches may also impact performance. These are harder to get around.
