One day, he was sitting on the plane, and the plane was sailing in a sleepy distance. His eyes looked out the window.
Scattered clouds cast mottled shadows in the field. When he looked down, he seemed to think that his life was as far away as a small house below, as the road network was leading to the Quartet wi
Playbook modules are somewhat different from the modules used under the Ansible command line. This is mainly because some facts variables and some variables obtained from the remote host through the Setup module are used in playbook. Some modules are not able to run under the command line, because they require these variables. And even those modules that can work at the command line can get some more advanced functionality through the Playbook module.
A factless fact table is a fact table this does not has any measures. It is essentially an intersection of dimensions. On the surface, a factless fact table does do sense, since a fact table was, after all, about facts. However, there is situations where has this kind of relationship makes sense in data warehousing.For example, think on a record of student attendance in classes. In this case, the fact table would consist of 3 dimensions:the student di

I wonder if you have noticed that you often say, "I like this idea, but should we do it in different ways ?"
Once you say the word "but", others will immediately forget the sentence th
What is Orm?Object-Role Modeling (ORM) provides a conceptual and easy-to-understand Method for modeling data. The ORM methodology is based on three core principles:
Simple:Data is modeled in the most basic form.
Communication:The database structure is documented in a language that anyone can understand.
Accuracy:Create a correctly standardized structure based on the data model.
Typically, modelers collect data from familiar applicationsProgramHowever, people who are not skill

Extract a few fields from a common large dimension to form a small field dimension that can be used in a query with a field in a mini dimension
This design significantly improves query efficiency

Induction and deduction
Inductive inference: Inductive reasoning,looking for the pattern or trend, and then generalizing, is a generalization, not necessarily the trend of the future, but suppose so.
Deductive inference: Deductive reasoning:taking Some set of data or facts, and using that to come up with other, or deducing some other F Acts that know is true. Deduction is true, is a p
