Database systems methodologies and technology can provide a significant support to data mining processes. In this chapter we explore approaches which address the integration between data mining activities and DBMSs from different perspectives. More specifically, we focus on (i) specialized query ...

DBMS_DATA_MININGパッケージは、Oracle Machine Learning for SQLモデルを作成、評価および問い合せるためのアプリケーション・プログラミング・インタフェースです。 Oracle Databaseリリース21cで、Oracle Data MiningはOracle Machine Learning for SQL (Oracle Machine Learning for SQL)にリブラ...
Data mining slowly evolves from simple discovery of frequent patterns and regularities in large data sets toward interactive, user-oriented, on-demand decision supporting. Since data to be mined is usually located in a database, there is a promising idea of integrating data mining methods into da...
Lastly, standardizing the interface among databases, data mining algorithms and applications can also facilitate the integration to certain extent.doi:10.1007/3-540-45357-1_3Lu, HongjunDBLPHongjun Lu.seamless Integration of Data Mining with DBMS and Applications. lecture note in Computer Scient . ...
一.DataMining 组件 说明 在说明之前,我们先用如下SQL查看一下DB中的组件: SQL> col comp_id for a15 SQL> col version for a15 SQL> col comp_name for a30 SQL> select comp_id,comp_name,versionfrom dba_registry ; COMP_ID COMP_NAME VERSION ...

11g, you may see this component indba_registry. This is because of the existence of DMSYS schema, which is notused in 11g and all the objects of DMSYS are shifted to SYS during the upgradeprocess. So once you drop DMSYS schema, 'Oracle Data Mining' willdisappear from the dba_registry...
预测查询生成的模型在此之后并不存在,也不可用于检查或调优模型。如果您需要检查模型、将评估结果与模型关联、指定特殊算法设置或使用同一模型执行多项评估查询,则必须使用 Oracle Data Miner Model Nodes 或使用一个名为 DBMS_DATA_MINING 的 Oracle Data Mining PL/SQL 程序包创建一个预定义模型。
function fn_mask_ssn (p_in varchar2) return varchar2 is begin return lpad ( round(dbms_random.value (001000000,999999999)), 9,0); end; end; / 该函数接受一个 varchar 参数,返回 9 个字符。我们将使用该函数来屏蔽 SSN。ACCOUNTS 表如下所示。
