This  dissertation deals with the formal design of three- dimensional spatial database systems and with  the need for abstraction in the design.  Use of  abstraction in the formal design of data models  allows a database system developer to consider the  comprehensive needs of users at an ideal level  unencumbered by implementation details.  The dissertation also presents a set of robust three- dimensional geometric primitives that could form the core of a discrete data model.  Although a  discrete data model is more concrete than SPAL3D, it has some abstraction.  The dissertation offers a  precise and conceptually clean specification and  foundation for implementing a Database Management  System (DBMS) extension for three-dimensional data. Assuming the existence of an implementation of this  type system, it demonstrates the embedding of the  spatial data types as attribute data types in  database schemas as well as the incorporation of the operations and predicates into queries  formulated in a possible extension of SQL.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838335445\"\u003e\u003ch3\u003eA Spatial Data Model\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838335445","offer_id":39499085447261,"sku":"9783838335445","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5704822f-a033-489c-b95a-8415cb9adee9.jpg?v=1755405553","url":"https:\/\/shop.autorenwelt.de\/products\/a-formal-design-for-three-dimensional-spatial-data-in-database-systems-von-brian-e-weinrich","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
