Examples of com.sleepycat.db.Database

com.sleepycat.db.Database
A database handle.
Database attributes are specified in the {@link com.sleepycat.db.DatabaseConfig DatabaseConfig} class.
Database handles are free-threaded unless opened in an environment that is not free-threaded.
To open an existing database with default attributes:
```
 Environment env = new Environment(home, null); Database myDatabase = env.openDatabase(null, "mydatabase", null); 
```
To create a transactional database that supports duplicates:
```
 DatabaseConfig dbConfig = new DatabaseConfig(); dbConfig.setTransactional(true); dbConfig.setAllowCreate(true); dbConfig.setSortedDuplicates(true); Database newlyCreateDb = env.openDatabase(txn, "mydatabase", dbConfig); 
```

        dbConfig.setType(DatabaseType.BTREE);


        // Create the Serial class catalog.  This holds the serialized class
        // format for all database records of serial format.
        //
        Database catalogDb = env.openDatabase(null, CLASS_CATALOG, null,
                                              dbConfig);
        javaCatalog = new StoredClassCatalog(catalogDb);


        // Open the Berkeley DB database for the part, supplier and shipment
        // stores.  The stores are opened with no duplicate keys allowed.
