This file contains :
1/ Class for expressing a session with the storage server
CMDBSession
This class contains functions to create and close a session, to set the dataset version and to request database actions such as locking for a transaction.
2/ Generic database functionality interface
MMetaDatabase
This class uses a CMDBSession object
3/ General base class that inherits from MMetaDatabase to express any database element
CMDBElement
This class contains the ElementId for each MetaDatabase object An element id locates stored data in the comms database.
4/ Data classes that each inherit from CMDBElement
a) Fields
CMDBField<T>
where T is a basic type value of the field (TInt, TDes, TBool etc)
This class derives from
CMDBElement
to implement the thin template idiom
CMDBRecordLink<T>
where T is a record of a particular type. This class expresses a soft-link from a field in one record to a record of a different type (i.e. in another table). The TMDBElementId value stored in this field in the repository is the id of an instance of the record of type T
This class derives from
CMDBRecordLinkBase
to implement the thin template idiom
b) Field Containers
CCDRecord
base class for record containing specific list of fields - see CommsDatTypesv1_1.h
CMDBRecordSet<T>
an array of records where T is the record type. This can represent a Table in a database.
5/ Other support classes and type definitions
TMDBElementId
The TMDBElementId locates a data object or set of data objects in the database.
A TMDBElementId expresses
A TMDBElementId has a different format depending on the data type it expresses
Table <0><0> Column <0>
Record <0> Field
TMDBAttributeFlags
Attribute settings for any storable element. Attributes express access control for data in the database

typedef struct CommsDat::SGenericRecordTypeInfoTag CommsDat::SGenericRecordTypeInfo;
To express type information for all MetaDatabase fields
const TMDBElementId KCDTIdRecordTag=0x00010000;
Field will contain a user-defined numeric tag for a record. Useful for user searches and cheaper to search on a numeric tag than a string name. Can be null. This tag is not automatically connected with the record id itself, which is contained within the ElementId for the record and not in any field.
const TMDBElementId KCDTIdRecordName=0x00020000;
Field will contain a user-defined string tag for a record. This is used to uniquely identify business level information within a record.
This field is useful for user searches, however it should be noted that it would be more efficient to use the KCDTIdRecordTag field instead as it is quicker and cheaper to search for a number than for a string.
