Peter McClintock. A short summary of this paper. The universe: order without design. Published in Contemp. Scope: monograph. ISBN Level: general reader. These questions are of course age-old. They arise naturally in the mind of every enquiring human but, in the last few decades, many of the answers have started to emerge at least in general terms.
Of course there are still many gaps in the story, e. But the overall picture seems compellingly clear to most scientists, and the general assumption is that the gaps will progressively be filled. It seems almost as though the Universe was explicitly designed in such a way that long-lived stars, planets, and life as we know it would eventually appear.
The author discusses several examples where the value of a physical constant is just right, and where even a tiny difference would have led to a totally different kind of Universe.
One of the seemingly least likely instances is the tuning of the fine-structure constant in just such a way that the energy of an excited state of the 12 C nucleus exactly matches the combined energies of a 8 Be and a 4 He, thus enabling the nucleosynthesis of carbon to occur in the interior of a star a coincidence predicted by Hoyle prior to its discovery on the grounds that, without it, nucleosynthesis of the higher elements would be impossible.
There are numerous other such coincidences, each one of which is separately essential for the present form of the Universe and without which we would not exist. It represents a category of objects. The name of a class should indicate the category of the objects that it contains. A class can be divided hierarchically into subclasses. Universe Designer Overview Objects An object is a named component that maps to data or a derivation of data in the database.
The name of an object should be drawn from the business vocabulary of the targeted user group Required skills and knowledge A universe designer should have the following skills and level of technical knowledge - Ability to analyze user needs - Database knowledge - Structured Query Language SQL. Tasks of the universe designer - Conducting user needs analysis - Designing and creating the universe - Distributing the universe - Maintaining the universe.
Building Universe Data Access drivers A Data Access driver is the software layer that connects a universe to your middleware.
Building Universe Design Schema - A graphical representation of database structure. Create Joins A join is a condition that links the data in separate but related tables. The tables usually have a parent-child relationship. If a query does not contain a join, the database returns a result set that contains all possible combinations of the rows in the query tables.
Such a result set is known as a Cartesian product and is rarely useful. Create Cardinalities Similarity between two tables Cardinality is a property of a join that describes how many rows in one table match rows in another table. This is core business intelligence BI technology that frees users from IT while ensuring correct results. An Info Provider can be:. BI Query: Subclass containing dimension and detail objects for each hierarchy level in the currently defined hierarchy.
Optimizing and Managing universes Optimizing universes - Using aggregate tables - Using Functions - Using external strategies to customize universe creation - Using analytic functions Managing universe - Deploying universes - Setting access restrictions on a universe - Linking universes - Managing users and logins.
Web Intelligence Overview Web Intelligence is a powerful analysis tool for creating ad-hoc reporting. It allows business user to analyze data from data warehouse. The reports created in WebI. It is a standalone Microsoft Windows Application to work with WebI documents off line without any InfoView connection and Application server installed.
So business user can now work with WebI on line and off line. You can work with following modes. Web Intelligence Report Design To create a new document in Web Intelligence Rich Client in Offline mode, you need to have a connection server installed on your computer. In the New Document dialog box, click Universe and then Next.
In the Universe dialog box, select a universe. The query panel opens to let you build your report. Using alerters to highlight results Merging dimensions from multiple data providers Ranking data in Web Intelligence reports Tracking changes in data Using sections, breaks and sorts Filtering reports Drilling on report data.
