RDBMSs are stable and mature products. While there is nothing radically new
on horizon that would challenge Codd's relational theory and related advances
in data processing there are some developments that force established vendors
like Oracle to come up with new features and products.
Column Stores and Oracle
Column store concept has been around for quite a while. Vendors like HP
Vertica grabbed some market share in data warehousing segment with their
column store, MPP databases. Oracle Exadata is offering Hybrid Columnar
Compression - solution that modifies Oracle standard row based storage
(NSM, or row-major) into proprietary format that is probably closer to PAX
(as opposed to DSM) classification. Rows of data are reo... (more)
Big shift towards Cloud environment has started. It is now clear that this
change is similar in magnitude to the shift from mainframe to client-server
computing two decades ago.
Amazon Web Services is the pioneer and market leader in Cloud computing
space. Other vendors are playing catch up and do not come close to the
breadth and scale of AWS offerings. Services and features Amazon provides are
quite extensive and cover many of the enterprise-class computing needs. APIs
and command line interfaces are available for each service, which makes
scripting and automation achievable. ... (more)
Ever wondered how it is possible that Google searches through so much data
with such speed and precision ?
Part of the answer is MapReduce, Google technology for processing and
generating large data sets.
Apache Hadoop is open source software that can process petabytes of data in
parallel on hundreds and thousands of commodity hardware nodes. It was
inspired by Google MapReduce. Oracle corporation is acknowledging the power
of Oracle/Hadoop combination by announcing Big Data Appliance - essentially
Hadoop/Oracle database software/Oracle hardware bundle, to be available next
Oracle Forms and Reports are Fusion Middleware components needed for OFA
installation. Forms is a GUI tool used to develop, generate and run database
front end applications. Reports is a GUI tool used to develop, generate and
run database reports. For the purposes of Oracle Fusion Applications
installation we will secure Forms and Reports with Identity Management.
Once you download and unzip Oracle Forms and Reports software and run
installer you will be presented with the welcome screen:
Forms installer will recognize WebLogic software we deployed in one of the
previous steps ... (more)
Machine Learning is a critical part of extracting value from Big Data.
Choosing proper model, preparing data and getting usable results on large
scale data is non-trivial exercise. Typically process consists of model
prototyping using higher level, (mostly) single machine based tool like R,
Matlab, Weka, then coding in Java or some other language for large scale
deployment. This process is fairly involved, error prone, slow and
Existing tools aiming at automating and improving this process are still
somewhat immature and wide scale Machine Learning enterprise adopti... (more)
