## Classes

| Class | Description |
| --- | --- |
| [DbCommand](./dbcommand/) | Database command. Objects of this class should only be allocated using [System::MakeObject()](../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../system/smartptr/) pointer and use this pointer to pass it to functions as argument. |
| [DbConnection](./dbconnection/) | Database connection. Objects of this class should only be allocated using [System::MakeObject()](../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../system/smartptr/) pointer and use this pointer to pass it to functions as argument. |
| [DbConnectionStringBuilder](./dbconnectionstringbuilder/) | API to build connection string of named fields. Objects of this class should only be allocated using [System::MakeObject()](../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../system/smartptr/) pointer and use this pointer to pass it to functions as argument. |
| [DbDataReader](./dbdatareader/) | API to receive data from database. Objects of this class should only be allocated using [System::MakeObject()](../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../system/smartptr/) pointer and use this pointer to pass it to functions as argument. |
| [DbProviderFactories](./dbproviderfactories/) | API to get DB provider factories. Objects of this class should only be allocated using [System::MakeObject()](../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../system/smartptr/) pointer and use this pointer to pass it to functions as argument. |
| [DbProviderFactory](./dbproviderfactory/) | Provider to access database. Objects of this class should only be allocated using [System::MakeObject()](../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../system/smartptr/) pointer and use this pointer to pass it to functions as argument. |
