Data mining has become a tool that allows companies to predict or describe your current events based on operational data base, all of which has revolutionized the software industry by the growth in storage and speed ...

One of the most important elements of an information system is the database, since it is the essential part which will safeguard all transactions that a company makes. For this reason it is important to know the types ...

The construction of a data warehouse involve determining the dimensions that must have, as well as the attributes that each will have, all within multidimensional architecture

This presentation shows all the service life to us that is due to realize for the design of a basic application of data.

When the program the student will understand the use of spreadsheet Intermediate - Advanced, you will have used this package for all types of graphics, applications databases.

We consider the Minimum Coverage Kernel problem: given a set B of d-dimensional boxes, find a subset of B of minimum size covering the same region as B. This problem is NP -hard, but as for many NP -hard problems on graphs, ...

Motivated by the analysis of range queries in databases, we introduce the computation of the Depth Distribution of a set mathcal {B} of axis aligned boxes, whose computation generalizes that of the Klee’s Measure and of ...

It is an open problem whether the 3-coloring problem can be solved in polynomial time in the class of graphs that do not contain an induced path on t vertices, for fixed t. We propose an algorithm that, given a 3-colorable ...

Both static and dynamic program verification approaches have significant disadvantages when considered in isolation. Inspired by research on gradual typing, we propose gradual verification to seamlessly and flexibly combine ...

We present a new compressed representation of free trajectories of moving objects. It combines a partial-sums-based structure that retrieves in constant time the position of the object at any instant, with a hierarchical ...
