Sequel uses the concept of datasets to retrieve data. ...

sequel by Jeremy Evans uses the concept of datasets to retrieve data.
A dataset object encapsulates an SQL query, letting the query fetch all the data by using a Ruby DSL.
Most important functions of Sequel 3.14.0:
• Sequel [sequel3.14.0.exe] provides thread safety, connection pooling and a concise DSL for constructing database queries and table schemas.
• Sequel - 0MB also includes a lightweight but comprehensive ORM layer for mapping records to Ruby objects and handling associated records.
• Sequel 3.14.0 supports advanced database features such as prepared statements, bound variables, stored procedures, master/slave configurations, and database sharding.
• Sequel makes it easy to deal with multiple records.
• Sequel currently has adapters for ADO, Amalgalite, DataObjects, DB2, DBI, Firebird, Informix, JDBC, MySQL, ODBC, OpenBase, Oracle, postgresql and SQLite3.
News in the current Sequel version:
• Add Dataset #set_defaults and #set_overrides, used for scoping the values used in insert/update statements
• Allow Models to use the RETURNING clause when inserting records on PostgreSQL
• Raise Sequel::DatabaseError instead of generic Sequel::Error for database errors, don't swallow tracebacks
• Use INSERT . . . RETURNING . . . with PostgreSQL 8. 2 and higher
• Make insert_sql, delete_sql, and update_sql respect the :sql option
• Default to converting 2 digit years, use Sequel. convert_two_digit_years = false to get back the old behavior
• Make the PostgreSQL adapter with the pg driver use async_exec, so it doesn't block the entire interpreter
• Make the schema generators support composite primary and foreign keys and unique constraints
• Work with the 2008. 08. 17 version of the pg gem
• Disallow abuse of SQL function syntax for types (use :type=> :varchar, :size=> 255 instead of :type=> :varchar[255])
• Quote index names when creating or dropping indexes
• Don't have column accessor methods override plugin instance methods
• Allow validation of multiple attributes at once, with built in support for uniqueness checking of multiple columns
• In PostgreSQL adapter, fix inserting a row with a primary key value inside a transaction
• Allow before_save and before_update to affect the columns saved by save_changes
• Make Dataset#single_value work when graphing, which fixes count and paginate on graphed datasets
