The four bases in a relationship, like in baseball, where the partners try to get home. First base is equivilent to french kissing, not just kissing. Knowledge Base from Wikipedia. Johannes concepts, semantic classes, and relationships like hyponymy (subclass-of) and meronymy. 1st Base - Is Kissing, french, open mouth or just a peck. Also any above the belt touching is included in this base 2nd Base - Hands below the belt. Fingering for.
This type of model looks similar to a star schemaa type of model used in data warehouses. When trying to calculate sums over aggregates using standard SQL over the master table, unexpected and incorrect results. The solution is to either adjust the model or the SQL. This issue occurs mostly in databases for decision support systems, and software that queries such systems sometimes includes specific methods for handling this issue.
The second issue is a 'chasm trap'. A chasm trap occurs when a model suggests the existence of a relationship between entity types, but the pathway does not exist between certain entity occurrences. For example, a Building has one-or-more Rooms, that hold zero-or-more Computers.
One would expect to be able to query the model to see all the Computers in the Building. However, Computers not currently assigned to a Room because they are under repair or somewhere else are not shown on the list. Another relation between Building and Computers is needed to capture all the computers in the building.
This last modelling issue is the result of a failure to capture all the relationships that exist in the real world in the model.

See Entity-Relationship Modelling 2 for details. Entity—relationships and semantic modeling[ edit ] Semantic model[ edit ] A semantic model is a model of concepts, it is sometimes called a "platform independent model".
It is an intensional model. At the latest since Carnapit is well known that: The first part comprises the embedding of a concept in the world of concepts as a whole, i.
The second part establishes the referential meaning of the concept, i. Extension model[ edit ] An extensional model is one that maps to the elements of a particular methodology or technology, and is thus a "platform specific model".What is BASE-RICHNESS? What does BASE-RICHNESS mean? BASE-RICHNESS meaning & explanation
The UML specification explicitly states that associations in class models are extensional and this is in fact self-evident by considering the extensive array of additional "adornments" provided by the specification over and above those provided by any of the prior candidate "semantic modelling languages". It incorporates some of the important semantic information about the real world.

Plato himself associates knowledge with the apprehension of unchanging Forms The forms, according to Socrates, are roughly speaking archetypes or abstract representations of the many types of things, and properties and their relationships to one another. Limitations[ edit ] ER assume information content that can readily be represented in a relational database. They describe only a relational structure for this information. At a certain stage of development, the material productive forces of society come into conflict with the existing relations of production or—this merely expresses the same thing in legal terms—with the property relations within the framework of which they have operated hitherto.
From forms of development of the productive forces, these relations turn into their fetters. Then begins an era of social revolution. The changes in the economic foundation lead, sooner or later, to the transformation of the whole, immense, superstructure.
In studying such transformations, it is always necessary to distinguish between the material transformation of the economic conditions of production, which can be determined with the precision of natural science, and the legal, political, religious, artistic, or philosophic—in short, ideological forms in which men become conscious of this conflict and fight it out. Just as one does not judge an individual by what he thinks about himself, so one cannot judge such a period of transformation by its consciousness, but, on the contrary, this consciousness must be explained from the contradictions of material life, from the conflict existing between the social forces of production and the relations of production.
Across these disciplines the base-superstructure relationship, and the contents of each, may take different forms. Max Weber[ edit ] Early sociologist Max Weber preferred a form of structuralism over a base and superstructure model of society in which he proposes that the base and superstructure are reciprocal in causality—neither economic rationality nor normative ideas rule the domain of society. In summarizing results from his East Elbia research he notes that, contrary to the base and superstructure model "we have become used to," there exists a reciprocal relationship between the two.

Political society consists of the organized force of society such as the police and military while civil society refers to the consensus-creating elements that contribute to hegemony. Both constituents of this superstructure are still informed by the values of the base, serving to establish and enforce these values in society.
Rodney states that while most countries follow a developmental structure that evolves from feudalism to capitalism, China is an exception to this rule and skipped the capitalism step. In China, religious, educational and bureaucratic qualifications were of utmost importance, and government was in the hands of state officials rather than being run by the landlords on their own feudal estates. Rather the role of the superstructure allows for adaptation of the development cycle, especially in a colonial context.
