7. * * Use Case Models

8. Functional Requirements 1/2 Manager Web AppDriver Viewing user’s schema; Selecting RDF endpoints; Creating relations; Editing schema and particular relations. Client App - Server App connect through JDBC postgres driver; PostgreSQL for transfering the query and result; Query parsing.

9. Functional Requirements 2/2 DBMSSemantic layer Query validation; Simple SELECT statements; Inner join on multiple relations. Querying (SPARQL) remote and local data sources; Retrieve source meta- data; Extandable with heterogeneous, distributed sources.

18. First requirements, creating teams, separating jobs MILESTONE /DELIVERABLE 1 MILESTONE/DE LIVERABLE 2 Milestones

19. Milestone 1

20. Communication Client/Server Definition of interfaces Basic functionalities for administration Basic parsing functionality Application works with ad hoc data Slightly behind schedule

21. Milestone 2

22. Integration of all layers Data types support All parsing functionality All functional requirements are fully implemented Application works with real world data Milestone 2

27. Divergent project tracks Project feasibility Team members leave the project Communication issues Integration problems Lack of experience Team members miss meetings Language misunderstanding Project Risks

28. First iteration results ●Front-end, DBMS and semantic assignments finished as supposed ●Problems with the type 4 JDBC client- server connection. Progress

29. Actions after first iteration/Second iteration Redistribution of work to finish the server-client part on the second iteration. Connection of all parts. Test of functionality with mocked data. Progress
