On Tuesday night, Oracle (Nasdaq: ORCL) treated investors to a massive shock. The rock-steady database giant doesn't miss earning estimates. It just doesn't. But this quarter, it did.

The shock spread far beyond Oracle itself. This event could only happen if enterprise software was suffering across the board, right? So, bellwether stocks IBM (NYSE: IBM) and Cisco Systems (Nasdaq: CSCO) fell about 3% while smaller, more volatile shares moved even further down. TIBCO Software (Nasdaq: TIBX), for example, lost as much as 13%.

And that's where TIBCO's own fourth-quarter report comes in. Whatever's ailing Oracle did not affect TIBCO at all.

Analysts wanted to see non-GAAP earnings of $0.35 per share on sales of about $281 million. The company delivered profits of $0.42 per share on $290 million in revenue. For the coming quarter, management laid out earnings guidance right in line with Street targets, but with an unexpectedly strong sales forecast.

CEO Vivek Ranadive underscored just how much Oracle's weakness really isn't affecting his company: "We're not seeing that softness that everyone is talking about, but in some ways that actually ends up helping us. Because again, people would rather put in our [information] bus and our [business process management] and our business eventing, against putting in a big iron, big database, big [enterprise resource planning] solution."

In short, TIBCO is winning in a weak economy thanks to innovative products that give customers a business advantage. Oracle is on the losing end of that equation.

The bigger picture may still be the same -- IBM and Microsoft (Nasdaq: MSFT) will either reinforce or debunk the idea of a soft enterprise software market in just a couple of weeks. But we have a couple of data points here from TIBCO and Linux vendor Red Hat (NYSE: RHT) that show how a sinking tide doesn't necessarily capsize all boats.
