Data model

Basic Implementation

Server

TBD

Client

TBD

DataSetImpl

Stores Item objects in "protected Map<Long,Item> items" - i.e. indexed by the id of the item - ids are Long values!

• getItems()
• getItemsByType(String type)
• getItemById(Long id)
• add(Item item) - add the item to the DataSet - after checking for duplicates (equal) items - return new item or merged item
• addForce(Item item) - add the item to the DataSet without looking for duplicates or merging

For creating new Item objects, the class DataFactory should be used:

• createItem(String type)
• createItem(String type, DataSet dataSet) - just set DataSet in Item - do NOT add to DataSet yet

DateSetImplDB (extends DataSetImpl)

Stores Item objects additionally in relational database - TBD tables

Item

Relevant functions for merging in DataSet

• getTypeString()
• getAttributeTNames()
• getRelationshipTypes()
• isEqualItem(Item item) - check if items are equal (should be merged)
• update(Item item) - merge item to the current one
