Here are some weaknesses of HDF5 according to NASA who was going to use it. Matlab mentioned as wel

Here are some weaknesses of HDF5 according to NASA who was going to use it. Matlab mentioned as well

Weaknesses: HDF5 is undeniably complex, and requires a significant learning curve. However, users also applaud the quality of documentation and help-desk support available. Third-party tools with HDF5 support, such as IDL and Matlab, also help hide complexity from users. Users have expressed concern about the availability of long-term support for HDF5 and related tools, but this concern is somewhat alleviated by the availability of the source code.

Applicability: HDF5 is used for data archive and distribution. The strengths cited above, together with the availability of analysis tools, make the format suitable for data analysis as well. The new netCDF 4.0 will include the capability to use HDF5 as the data storage layer for the netCDF API, with the addition of many new features available in HDF5 such as user defined types, multiple unlimited dimensions, and per-variable data compression. This merger of the two formats will further extend the HDF5 user community.

Limitations: A major limitation for HDF5 is the loss of backward compatibility with HDF4 and earlier versions. Also, unlike less complex formats, users cannot read the HDF5 files directly without using the HDF5 software library. Of greater concern are recent postings on a mailing list discussing use of netCDF and HDF5 in high performance computing applications with thousands of processors using parallel I/O, which warn of the danger of file corruption during parallel I/O if a client dies at a particular time. The HDF Group is aware of this problem and is addressing it.

Overall, HDF5 is a widely used data format with a well-defined specification that provides a standard way of storing and working with science data. The ESDS-RFC-007 TWG thus recommends its endorsement by the SPG as an Earth Science Data Systems Standard.

Sadly, I would therefore not consider this an option for my infrastructure!!

The accidental merging of Marketcetera and Quantlib seem to complement each other’s weaknesses brilliantly

The accidental merging of Marketcetera and Quantlib seem to complement each other’s weaknesses brilliantly
Ok. I started thinking if I was going to start working on Java based strategies, would it not make sense to use ActiveQuant? I started researching to see where this framework was at. I always would have used Quantlib since it was developed in faster C++ but Java looks like it will be for the time being. Thus, we have ActiveQuant. It seems they have made some great strides at both sites of activequant.org and activestock.eu. Some nice features that will be very useful:
1. Download market history from both Open Tick, Yahoo and Interactive Brokers. I should be able to leverage Marketcetera’s features and technical trading strategies with this quite nicely.
2. Some very decent documentation and wiki support for this framework. I do like Quantlib but it lacks here. There is not much example stuff out there compared to JQuantlib or ActiveQuant. I do think Quantlib is still the ultimate in terms of functionality. It is just their Quantlib SWIG blows with scant documentation and assumptions they make the developer will be up and running fast. Bah humbag.
3. Tonnes of new upcoming features including the ability to integrate with Hibernate or Ibatis to connect to other commercial databases including Oracle or Microsoft SQL Server.
4. Also, but awesome idea of Forwardtesting on Interactive Brokers (Paper Account)
I am quite excited to integrate ActiveQuant and Marketcetera somehow. I do think there will be some efficiency limitations as I scale up. I shall work on that in the future. That is not a major limitation right now but could be.
I will let you know how this goes but I have no hold off on anything Quantlib for now. I just wish I could get up and running faster than before. We shall see and I will keep you up to date.
