Example - Select individual fields from one table

You can also use the SQL Server SELECT statement to select individual fields from the table, as opposed to all fields from the table.

The way we demo QlikView at this stage usually involves creating a targeted QlikView document that uses the customer's actual data in a limited amount of time.

Question
What is a Data Model?
Answer
The heart of a QlikView application is its data model. It is composed of the different source tables that contain the information and data used to measure a company's performance. The data model is constructed by using QlikView's scripting language. A correctly-built data model will associate all of its tables in a way which allows us to manipulate the data however we like. This means that the creation of analysis objects (charts) across different dimensions depends mainly on how the data model is built and how its tables are associated (how they are linked to each other).

The outline of the algorithm is 1. Fix the number of clusters at some integer greater than or equal to 2 2. Start with the “centroids” of each cluster; initially you might just pick a random set of points as the centroids 3. Assign points to their closest centroid; cluster membership corresponds to the centroid assignment 4. Reclaculate centroid positions and repeat.

Segundo a doutrina, trata-se de uma retroatividade média.

Art. 105. A legislação tributária aplica-se imediatamente aos fatos geradores futuros e aos pendentes, assim entendidos aqueles cuja ocorrência tenha tido início mas não esteja completa nos termos do artigo 116. (situação de fato ou de direito).

"Ocorre a retroatividade máxima (também chamada restitutória) quando a lei nova retroage para atingir os atos ou fatos já consumados (direito adquirido, ato jurídico perfeito ou coisa julgada).
A retroatividade média, por outro lado, se opera quando a nova lei, sem alcançar os atos ou fatos anteriores, atinge os seus efeitos ainda não ocorridos (efeitospendentes) . É o que ocorre, por exemplo, quando uma nova lei, que dispõe sobre a redução da taxa de juros, aplica-se às prestações vencidas de um contrato, mas ainda não pagas.
Já a retroatividade mínima (também chamada temperada ou mitigada) se verifica quando a novel lei incide imediatamente sobre os efeitos futuros dos atos ou fatos pretéritos, não atingindo, entretanto, nem os atos ou fatos pretéritos nem os seus efeitos pendentes . Dá-se essa retroatividade mínima, quando, por exemplo, a nova lei que reduziu a taxa de juros somente se aplicar às prestações que irão vencer após a sua vigência (prestações vincendas). A aplicação imediata de uma lei, que atinge os efeitos futuros de atos ou fatos pretéritos, corresponde a uma retroatividade, ainda que mínima ou mitigada, pois essa lei retroage para interferir na causa, que é o próprio ato ou fato ocorrido no passado."
