Berkeley DB is really difficult to use, there are [sophisticated Wrapper](https://github.com/rpm-software-management/rpm/tree/master/lib/backend) and [Controller Interface](https://github.com/rpm-software-management/rpm/blob/master/lib/rpmdb.c) for rpm usage.

I prefer to use SQLite3, so I totally rewrote the pkgcache generation [APT-RPM](http://apt-rpm.org/scm/?p=apt.git;a=summary), it is quite simple to use SQLite table to store Package information about ***Requires*** and ***Provides*** for Building Dependency Tree ;-)

```
CREATE TABLE `Package` (
	`Name`	TEXT NOT NULL UNIQUE,
	`Version`	TEXT NOT NULL,
	`Release`	TEXT NOT NULL,
	`Arch`	TEXT NOT NULL,
	`IGroup`	TEXT NOT NULL,
	`Uri`	TEXT NOT NULL,
	`Requires`	TEXT,
	`Provides`	TEXT,
	`Md5`	TEXT,
	`Status`	INTEGER NOT NULL DEFAULT 0
);
```
