OLAP
With
the advent of Data warehouses it became clear that the managing huge amounts
of data and attempting to analyze and comprehend it called for
different methods than the traditional ones.
OLAP stands for On Line Analytical Processing and refers to a category
of applications that focus on quick delivery of answers when faced with
a data warehouse. Since collections in this model are usually
multidimensional, OLAP applications must have the ability to filter data
as needed and deal with both large and small scale levels of
aggregation.
Therefore a common usage pattern is the visualization of requested data
into a cube structure. Each dimension of the cube is user-specified.
The user can rotate the cube, slice it, drill down and up in order to
achieve different views of the same dataset. This ability allows for
effective analysis of the data at hand even though the datasets
employed are far larger than those handled by traditional database
application.
Contrast this concept with OLTP (Online Transaction Processing) which
reflects the model used with traditional applications. Commonly employed
by databases OLTP focuses more on transactions, speed, reliability and
performance rather than aggregation and multidimensional data.
You can consult the wikipedia entry on OLAP for additional information.
Agilis has wide expertise in OLAP applications and one of its flagship
products implements the cube approach as explained. Traditional OLTP
solutions are also offered if requested.
