I deleted a response when I saw that the base post was about 18 months old. However, I'll repeat my idea here since the thread is active.
It wasn't clear (to me anyway) that online access was necessary since the requirement was for read only data. And it's been years since I worked with Oracle, but I know there were utilities to import/export tables/views etc from Oracle. So if read only was required, such a file(s) could be made available for reading even though it would have some time delay from the online system.
I agree with DocMan that IT database/security can seem to be a world unto itself --but there are often good reasons. And, as he said, if the requirement to access online data originated with management, the powers to be will evaluate and make it happen.
From experience, I also worked in a federal government organization. After a multi department merger we developed online, integrated corporate database and applications. The subject matter of relevance here is the application and approval of grants and loans to various people/orgs distributed across the country. Previously, there were individual applications typically batch mode where officers could get reports on actual vs projected spending; and using their experience could revise projections based on take up. However, with the online and integrated systems, the actual spend numbers were available instantly - and changing by the minute or second from across the country. The data was or could change at anytime; there was no longer a wait time whereby officers could "adjust projections".
Some areas, based on their previous work practices, needed online access to the data.
This need was reviewed. The solution was to extract data from the online system at the month-end, quarter-end, year-end and fiscal year-end and make it available Read Only. The data in each of the "files" was consistent (not changing instantly as the online system did). Officers could run multiple reports, queries, what-if scenarios etc repeatedly and get the info needed for their work. This extracted data and the major associated processing was known as the Management Reporting Database.
All this to say that for read only access to data, there may be some extract options.
Good luck.
