The com.slamd.db package contains the code for interacting with the embedded database. This database stores all configuration and job data. The embedded database used is the Berkeley DB Java Edition, which is not a relational database but rather a BTree database, so it is not accessed via JDBC and data is not stored in rows and columns, but rather each database operates very much like a java.util.TreeMap in which elements are sorted key-value pairs that may be get and put as necessary.
