The principle class for most eXtremeSQL C++ applications is McoSqlEngine or for multi-threaded applications McoMultithreadedSqlEngine. However, functionality for managing transactions and executing prepared statements is provided in the McoSqlSession class. The McoSqlEngine instance may use McoSqlOpenParameters to specify parameters for opening a database. The McoSqlEngine method
executeQuery()returns QueryResult instance which provides a number of method for processing query result sets.Access to remote SQL server is provided by class RemoteSqlEngine and an application can create a SQL server by instantiating SqlServer.

SqlEngine Implements functionality common to subclasses McoSqlEngine , McoMultithreadedSqlEngine, RemoteSqlEngine and SqlServer McoSqlEngine Implements eXtremeSQL database open(), close(), executeStatement(), etc.McoMultithreadedSqlEngine Implements eXtremeSQL database multi-threaded and distributed SQL access McoSqlOpenParameters Specifies parameters for opening an McoSqlEngine instance SqlOptimizerParameters Specifies options for tuning performance of the SQL engine. McoSqlSession Used to share a single database connection between multiple threads Implements eXtremeSQL database remote server access
DistributedSqlEngine Implements eXtremeSQL client interface for distributed execution of SQL queries
AsyncDistributedSqlEngine Implements eXtremeSQL client interface for distributed asynchronous execution of multiple SQL queries
SqlServer Executes client SQL requests. Transaction Provides the capability of interacting directly with a transaction that performs a number of database operations QueryResult Data set for SQL query results DataSource This is an abstract class and cannot be instantiated directly; it is instead typically instantiated though a QueryResult object Cursor Provides an iterator object for scrolling through the individual rows of a result set in a QueryResult Table Provides access to the tables in an eXtremeDB database Record A database record; typically a row of a result set Field Represents a field in a database Record String Provides methods for handling character stings Struct Provides methods for handling compound structure Values Array Provides methods for handling Arrays of Values NullableArray Provides methods for handling Arrays of Values with possible null values List Provides methods common to Strings and Arrays. Index Represents a database table index Key Represents a component in an Index Sequence The generic class for managing database fields of type sequence. Value A generic base class that implements the methods for classes List, Array, String, Struct and Record
