With the recent (April 2010) SOA Suite 11g R1 Patch Set 2 (11.1.1.3.0), several new capabilities have been added to the SOA Suite.

Publish SOA Composite application as EJB to be invoked from Java applications using EJB Binding
Donderdag as. is de AMIS Query van Doug Burns over SQL Tuning, gebruikmakend van de Oracle Enterprise Manager (Tuning en Diagnostics pack). Misschien verwachten velen een hoog “DBA” gehalte, maar niets is minder waar… Deze presentatie bevat bijna geen enkele slides en is echt een aanrader om bij te wonen.

In a recent post I described how we can use the EJB Binding in SOA Suite 11g PS2 to invoke a SOA Composite application through RMI as a remote EJB. This interaction can be fully based on Java interfaces – no WSDL or XML required

‘Oracle Team Productivity Center (TPC) is an Application Lifecycle Management (ALM) tool that enables software development teams to collaborate and work productively together when developing applications using JDeveloper.’ (OTN TPC page) TPC provides unified access to different ALM repositories from within JDeveloper and it allows to define relations between the so-called work-items in these (separate) repositories.

See EMC’s press release on the deal here . First, some takeaways from the press release and related coverage: All cash transaction, valuation undisclosed. See below for some fun and math, trying to guestimate it from standard ratios. Greenplum had raised $61M in venture capital. EMC intends to create a new “data computing” product division and to have Greenplum CEO Bill Cook run it, reporting to Pat Gelsinger .

Long-term database guy and MarkLogic VP of Engineering Ron Avnur said that at our last user conference that MarkLogic was “ NoSQL before NoSQL was cool.” He even made up about 500 t-shirts with that slogan on them and handed them out. See Ron if you want a t-shirt. See this post if you want my analysis of his statement. Let’s look first at what MarkLogic is about: Unstructured data. This means not only dealing with data in odd structures (e.g., sparse and/or semi-structured data), but also handling words and all the challenges that go with them

Visualization tools startup Palantir announced a follow-on financing round yesterday, raising $90M at a claimed $735M valuation . Since most people aren’t familiar with either finance or VC math , this can generate confusion so I thought I’d do a post explaining a few things. The first is simple: do not confuse valuation with revenue . Valuation (or for public companies, market capitalization) is an implied metric based on per-share price and number of shares outstanding. For example, a public company with 50M shares and a $20 share price has a valuation of $1B. That alone says nothing about its revenue. TechCrunch makes this mistake three times in the story, calling Palantir “the next billion-dollar company” in the headline, saying they’re a “near-billion dollar company” in the middle, and at the end, saying they are close: It’s hard to imagine a billion-dollar company without a sales team, but then again Palantir is getting pretty darn close
