what I mean is not really the same feature as SQL Server has, but all features regarding reading from a file. I've read your reply to hdf forum as follows:
True concurrent access to a file when it is being written to is not currently supported. We are working to add a single-writer/multiple-reader access mode for the next release (1.10.0), but it's not available yet. The current way to have pseudo-concurrent access to a file is found here: http://www.hdfgroup.org/hdf5-quest.html#grdwt Quincey therefore, this H5Fflush is able to handle concurrency for reading a file? thanks --- On Wed, 8/18/10, Quincey Koziol <[email protected]> wrote: From: Quincey Koziol <[email protected]> Subject: Re: [Hdf-forum] Handle concurrency, transaction (or any features provided) in HDF5 compare to SQL Server To: "HDF Users Discussion List" <[email protected]> Date: Wednesday, August 18, 2010, 9:47 AM Hi Elisa, On Aug 18, 2010, at 12:28 AM, elisa sibarani wrote: > Hi all, > > I want to ask is there anyone of you can shares information about HDF5 > features available until now?

How I can get such information about HDF5? HDF5 does not have transactions, concurrency or replication features. It is not a database. It is designed for storing and sharing large array-like datasets in a hierarchically structured file (see http://www.hdfgroup.org/HDF5/whatishdf5.html for some more details and documentation).
