The properties of relational database management systems (DBMSs) are discussed. It is shown how they can be used as an effective tool for performing the function of primary-key-coding schemes for classifying product families in the application of group technology. The attributes of the relational...
In fact, in most DSS a commercial DBMS or RDBMS package is used to perform this task. The Query Control – this is a tailored element to handle the query requirements of DSS. It may connect the database, directly to the user interface or to the model base or both. Meta Data – this...
In the call toCTX_CLS.TRAIN,use theSVM_CLASSIFIERpreference instead of theRULE_CLASSIFIERpreference. (If you do not want to modify any attributes, use the predefinedCTXSYS.SVM_CLASSIFIERpreference.) Use theNOPOPULATEkeyword if you do not want to populate theCONTEXTindex on the table. The class...
4.2 Query Skew (QS) This term denotes the bias in query predicates, which normally tend to select certain relations, attributes, or values more frequently than others. Like intrinsic skew, query skew derives from the logical view of the data independent of the storage or processing approach, ...

This paper proposes an approach to software classification in fine-grain based on SLIQ algorithm,uses testing tools and writes API’s to get both inner and outer attributes of software,cleans these data and abstract classification rules of software,and builds a classifying model applied in DBMS cl...
