A Novel Query-Based Approach for Addressing Summarizability Issues in XOLAP

Fig. 6 shows the code for defining the class-to-table example in ETL. Inten- tionally, the code font size used is very small in the figure, since we will not discuss in detail each

In this paper, we provide our vision of a method using machine learning techniques to predict whether a QEP should be optimized or not during the query execution, so that the

Il s’agit de la description d’un cas observé par le docteur Joannes Actuarius (v. Baumes rappelle que Plancus avait déjà publié le même cas en 1756, soit onze ans auparavant. )

Nous avons opté pour des briques de type file d’attente car notre métho- dologie s’adresse à des systèmes dans lesquels les clients occasionnent des délais de service

Suppose that we run a model-checker and got a labelled transition system (LTS), a graph re- sulting of the exploration of Alice and Bob system with a modelling error and the

The lower bound is proved by examining the decision tree of the deterministic query scheme and exhibiting an input for which the number of queries asked is high.. More precisely,

If a join query node process receives construct_vars messages from inner and outer query nodes, it merges both variable lists and sends the merged list to its parent query node

The right outer join (or right join) will return rows that have data in the right table, even if there’s no matching rows in the left table enhanced by atteributes (with NULL values)
