What executes SQL commands submitted by an application program, if no DBMS is running?
问题 When you are writing a program which uses a database driver, from Why is programming interface to database called driver? There are databases that allow you to embed them within your process (like sqlite) , but if you're working with a database that has its own process[es] (like postgresql), then yes, it(they) must be up and running in order to work against that database. So some databases "allow you to embed them within your process (like sqlite)". If there is no DMBS running, to what does
Tutorials For Database-Driven Routing in Zend Framework?
问题 I am working on a project that needs to use a database driven MVC scheme where the route to the controllers and views are controlled through a single database table. However, I haven't been able to find any tutorials that demonstrate this with a current version of the framework (they all appear to have been written several versions ago) and I was wondering if anyone has done something like this with a more recent version of the framework or if anyone knows of blogs or tutorials that discuss
Why is programming interface to database called driver?
问题 When writing an application which updates or queries a database, we use something called a database driver (e.g. a JDBC driver). I wonder why it is called a driver instead of a library? Is libpq a driver too? 回答1: To quote the Wikipedia article you linked to: In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer. The analogy here is that a database is an external device that the client computer "controls", by
ASP.Net MVC Database-driven menu with caching
问题 I am trying to create a menu for my website. It needs to meet the following requirements it must be database driven, pulling data from DB to build up the menu structure the data being pulled from the DB needs to be cached - I do not want to hit the DB for each page request At the moment, I have a simplistic example running, but I don't know how to integrate caching. I think I might have to rework the entire way I do this. Here it is: I have a ProductMenuAttribute , which pulls the data from
Enum with constant and also dynamic values from database
问题 I have a current state where an enum MyType represent Type table with columns as: ID Name And it's used to identify type using ID parameter with byId method: public enum MyType { FIRST_TYPE("First Type", 10), SECOND_TYPE("Second Type", 20); public static class Holder { static Map<Integer, MyType > idMap = new HashMap<>(); private Holder() { } } private MyType(String name, Integer id) { this.name = name; this.id = id; Holder.idMap.put(id, this); } public String getName() { return name; }

Embedded PostgreSQL for Java JUnit tests
Is there an embedded PostgreSql so that we could unit test our PostgreSql driven application? Since PostgreSql has some dialects, it's better to use embedded PostgreSql itself than other embedded databases. Embedded does not necessarily mean it must be embedded in the JVM process. It also does not necessarily need to use in-memory persistence. It should be loaded automatically by the dependency management (Maven, Gradle), so that Unit tests can run on every machine without having to install and configure a local PostgreSQL server. No, there is no embedded PostgreSQL, in the sense of an in
