System Goal

* * Use Case Models

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.

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.

Agile Software Development Week iterations(7) Steps: 1.Detailed week plan 2.Identify problems 3.Design 4.Implementation 5.Testing 6.Integration Development methodology

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

Milestone 1

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

Milestone 2

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

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

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

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
