+  - name: "Group Project - AirVia ATS (AirTicket Sales)"
+    content: >
+      <p>
+      This group project was creating a Ticket Sales system for the fictional company AirVia LTD, for this the group had to both design the implementation and then write the code for it.
+      Unfortunately, the project was not finished to a state where all the required features were added in and while all of the backend functionality except for the reports existed,
+      the GUIs to view and control those backends was not available.
+      Examples of this include: Sales, Transactions, Discounts and Reports where no GUIs were created or finished for any of these components.
+      The design of the program was followed with a lot of adaptations (Rather than not being followed at all) and it architecturally made sense with the use of facade implementations;
+      The use of facade allowed for other people to code against an interface while waiting for a controller to be finished which extended the interface.
+      </p>
+      <p>
+      The database system was handled via an abstraction layer I designed and wrote myself which supports 'locking' a record for keeping consistency when multiple instances of the program are running.
+      This system uses an auxiliary table that has only the primary key column, a record is locked if it does not exist in the auxiliary table (Cannot delete) and is not locked if it does (Cannot insert);
+      This allows for atomic locking and unlocking of the record.
+      The implementation requires the record locked for safe access (Loading, Storing).
+      The abstraction layer makes use of two base classes, one for a single record and one for a table; with tha table one allowing the creation and deletion of the extending table via a schema and name being provided (As seen in the source code).
+      I also developed a backup system for the database that supports any table with the specifically supported data types used in the tables defined in the schema - removing the need to use third-party programs like SQLDump.
+      </p>
+      <p>
+      In the end, the following features were implemented: Login, Help / Error / Status Bar, Account System + GUI, Blank Types + GUI, Blanks + GUI, Customers + GUI, Discounts, Flexible Discounts, Sales, Transactions, Refunds, Dashboard + Notifications, Database Interfacing + Backup and Rates + GUI.
