-# = Introduction
-#
-# A typical sequence of events is as follows:
-# Create a database instance (handle), invoke query using the database handle to send the statement to the server and get back a result set object.
-#
-# A result set object  has methods for fetching rows, moving around in the result set, obtaining column metadata, and releasing the result set.
-# A result set object is an instance of the MonetDBData class.
-#
-# Records can be returned as arrays and iterators over the set.
-#
-# A database handler (dbh) is and instance of the MonetDB class.
-#
-# = Connection management
-#
-#  connect    -  establish a new connection
-#                * user: username (default is monetdb)
-#                * passwd: password (default is monetdb)
-#                * lang: language (default is sql)
-#                * host: server hostname or ip  (default is localhost)
-#                * port: server port (default is 50000)
-#                * db_name: name of the database to connect to
-#                * auth_type: hashing function to use during authentication (default is SHA1)
-#
-#  is_connected? - returns true if there is an active connection to a server, false otherwise
-#  reconnect     - reconnect to a server
-#  close         - terminate a connection
-#  auto_commit?  - returns true if the session is running in auto commit mode, false otherwise
-#  auto_commit   - enable/disable auto commit mode.
-#
-#  query         - fire a query
-#
-# Currently MAPI protocols 8 and 9 are supported.
-#
-# = Managing record sets
-#
-#
-# A record set is represented as an instance of the MonetDBData class; the class provides methods to manage retrieved data.
-#
-#
-# The following methods allow to iterate over data:
-#
-# fetch          - iterates over the record set and retrieves one row at a time. Each row is returned as an array.
-# each_record    - works as ruby each method. The method takes a block as parameter and yields each record to this block.
-# fetch_hash     - iterates over the record set and retrieves one row at a time. Each row is returned as a hash.
-# each_record_as_hash - works as ruby each method. The method takes a block as parameter and yields each record, as hash, to this block
-# fetch_all      - returns all rows as a two dimensional array
-# fetch_all_as_column_hash - returns all records as a hash with the column name as the keys and an array with all column values as values
-#
-# Information about the retrieved record set can be obtained via the following methods:
-#
-# num_rows       - returns the number of rows present in the record set
-# num_fields     - returns the number of fields (columns) that compose the schema
-# name_fields    - returns the (ordered) name of the schema's columns
-# type_fields    - returns the (ordered) types list of the schema's columns
-#
-# To release a record set MonetDBData#free can be used.
-#
-# = Type conversion
-#
-# All values from the database are converted to the closest ruby type, i.e: INTEGER to int, TIME to time, CLOB to string
-# Some of the more complex datatypes are not recognized, such as INTERVAL, these are converted to strings
-#
-# = Transactions
-#
-# By default monetdb works in auto_commit mode. To turn this feature off MonetDB#auto_commit(flag=false) can be used.
-#
-# Once auto_commit has been disable it is possible to start transactions, create/delete savepoints, rollback and commit with
-# the usual SQL statements.
-#
-# Savepoints IDs can be generated using the MonetDB#save method. To release a savepoint ID use MonetDB#release.
-#
-# Savepoints can be accessed (as a stack) with the MonetDB#transactions method.
-#
-# demo.rb contains usage example of the above mentioned methods.
