About Solitec
Vienna-based SOLITEC Software Solutions GmbH was founded in 1997 as a spin-off by former employees of Cap Gemini Austria. As an independent software company SOLITEC focuses on delivering high quality turnkey IT solutions and services based on state-of-the-art OracleÒ Technology from the very beginning. Since 1998 SOLITEC is one of the first Certified Solution Partners of OracleÒ in Austria. They carry out even the most complex IT projects by using reliable methods and tools and by permanent education of their employees and co-operation with external Business Consultants. Within the scope of our successfully delivered large-scale projects we have gained valuable domain expertise in aviation, insurance/finance, government/public authority and transportation/logistics. Our company's policy reads as follows: "Keep your customers AND your employees for life".

Subsystem SDO
The subsystem SDO is a new development within the scope of EAD and serves as the "Data Backbone" for other subsystems like AIP (Aeronautical Information Publication), Charting (Aeronautical Chart Production) and INO (International NOTAM Operations). All static data as defined in the AIXM (Aeronautical Information Exchange Model) data model is contained in the SDO database and is accessed and/or maintained via functionalities provided by SDO.

SDO Slot Management
Slot Management provides a publishing mechanism to co-ordinate and check static data updates for which multiple Data Providers are responsible. A set of related static data updates for one Data Provider is called a private slot. A set of private slots with the same effective date is called a public slot that can only be maintained by EAD staff. Private slot validation checks static data within a private slot against published data and includes category B checks. Public slot validation checks static data against published data and also against all private slots within the same public slot and includes category C checks.

SDO Static Data Maintenance
Static Data Maintenance is fully based on Slot Management. Static Data Maintenance provides an AIXM-based comfortable access layer to update the SDO database, which prevents clients from directly accessing the SDO objects in the SDO database. It also makes the implementation details of temporality and traceability transparent to clients. It maintains the integrity of the database by performing category A data checking on all data input. Static Data Maintenance maintains spatial attributes to make spatial queries possible (e.g. all VORs within a region).

SDO Reporting
In order to have read access to static data contained in the SDO database, report functionalities (queries against the SDO database) are provided by SDO for Data Users and Data Providers. A set of predefined reports (useful reports of common interest) is provided by SDO. Furthermore, SDO provides facilities to allow the creation of user-defined reports. For Public Users accessing EAD via the Internet only predefined reports are foreseen.

SDO Bulk Upload / Download
AIXM Upload: The AIXM Upload is responsible for processing a file containing aeronautical data in AIXM (XML syntax) exchange format. The data is checked, and stored in the database, using the Static Data Maintenance and Slot Management software. The data is accompanied by identification of the Responsible Authority. AIXM Upload is fully under control of EAD staff.

AIXM / ARINC Download and Data Distribution: The AIXM/ARINC Download and Data Distribution is responsible for extracting static data from the SDO database, using Parameter Sets specifying the selection criteria, such as region, entities, and format. The data is formatted in accordance with either the ARINC 424 or AIXM (XML syntax) exchange format. The resulting data file is passed on to the EAD Office for on-line or off-line transport to the authority who requested the download. The delivery of data files through on-line transport is not part of SWU SDO but of the ESI. Parameter Sets can only be updated by EAD staff. Because AIXM/ARINC Download and Data Distribution are only triggered by Parameter Sets, it is fully under control of EAD staff.

SDO Parameter Set Management
Parameter Set Management provides services for EAD staff for managing the Parameter Sets for User Profiles, as well as the contents of Parameter Sets, which are used for AIXM / ARINC Download and Data Distribution. Parameter Sets contain, among others, a description of the type and frequency of the delivery and format of the output file.
