Discusses how to define a dataset from an analysis services multidimensional database 介紹如何從analysisservices數(shù)據(jù)庫中檢索數(shù)據(jù)。
Use management studio to develop scripts for relational and multidimensional databases, and all types of queries 使用managementstudio可以為關(guān)系數(shù)據(jù)庫和多維數(shù)據(jù)庫以及所有查詢類型開發(fā)腳本。
An application that retrieves data from a server and performs local analysis and presentation of data from relational or multidimensional databases 一種sqlserver系統(tǒng)數(shù)據(jù)類型,存放從0到255之間的所有數(shù)值。其存儲大小為1個字節(jié)。
You can use a sql server relational database, an analysis service multidimensional database, an oracle database, or any of the other supported data sources 可以使用sqlserver關(guān)系數(shù)據(jù)庫、analysisservice多維數(shù)據(jù)庫、oracle數(shù)據(jù)庫或任何其他支持的數(shù)據(jù)源。
The way you specify data that you want depends on the data source itself : relational databases can use transact-sql queries or stored procedures, multidimensional databases can use multidimensional or data mining queries, xml documents or web services can specify queries with or without namespaces, report models can use report model metadata queries 在數(shù)據(jù)集中指定查詢時,所使用的查詢語法取決于數(shù)據(jù)源類型的查詢語言。例如,如果使用sqlserver關(guān)系數(shù)據(jù)庫中的數(shù)據(jù),則查詢將包括transact-sql語句。
So the concepts of multidimensional database and multidimensional analysis are put forward, viz . on-line analytical process, it gives analyst, manager, or executor the ability of information access which is rapid, accordant and interactive from multi point of view . the information comes from original data, and can be catch on by consumer and really reflects the character of enterprise dimension 因此提出了多維數(shù)據(jù)庫和多維分析的概念,即聯(lián)機(jī)分析處理(on-lineanalyticaiprocess),它是使分析人員、管理人員或執(zhí)行人員能夠從多種角度,對從原始數(shù)據(jù)中轉(zhuǎn)化出來的、能夠真正為用戶所理解的并真實(shí)反映企業(yè)維特性的信息進(jìn)行快速、一致、交互地存取,從而獲得對數(shù)據(jù)的更深入了解的一類軟件技術(shù)。
Confronted with the massivedatas in the multidimensional database, regressing analysis model is applied to forcast and to help decisions . as far as knowledge discovery is concerned, the association rulesmethods are choosed to complete the data mining . the useful knowledge is drawn out of the database to realize the decision support . the realization of dalian maritame university information decision support system will improve the decision quality effectively . direct and hamonize the development of science and research, accelerate science and technology boom, and make dalian maritame university to hold her advantage in sc ience and technology competition in the new surroundings and forms 在知識發(fā)現(xiàn)方面選擇了關(guān)聯(lián)規(guī)則方法完成數(shù)據(jù)挖掘,抽取數(shù)據(jù)庫中的有用知識,實(shí)現(xiàn)對決策的支持。海事大學(xué)科技管理與決策系統(tǒng)的實(shí)現(xiàn)將有效地提高決策的質(zhì)量,更好地指導(dǎo)和協(xié)調(diào)科研工作的發(fā)展,促進(jìn)科技繁榮。使海事大學(xué)在新環(huán)境、新形式下的科技競爭中處于優(yōu)勢地位。
