Normalizationis a process of organizing the data in database to avoid data redundancy, insertion anomaly, update anomaly & deletion anomaly. Let’s discuss about anomalies first then we will discuss normal forms with examples. Anomalies in DBMS There are three types ofanomalies that occur when the...
Monitor across a variety of DBMS. Database Performance Analyzer monitors all these databases from a single installation: SQL Server, Oracle, MySQL, MariaDB, Aurora, DB2, and SAP ASE, spanning on-premises and cloud. Quickly find the root cause of your complex database problems. Anomaly detection...

Database Intrusion Detection Systems (DIDs): Insider Threat Detection viaBehaviour-Based Anomaly Detection Systems - ABrief Survey ofConcepts andApproachesdoi:10.1007/978-3-030-93956-4_11One of the data security and privacy concerns is of insider threats, where legitimate users of the system abuse...
Efficient processing of complex streaming data presents multiple challenges, especially when combined with intelligent detection of hidden anomalies in real time. We label such systems Stream Anomaly Monitoring Systems (SAMS), and describe the CMU/Dynami
If you’ve found a performance anomaly and further investigation has led to the discovery that the query optimizer is choosing an incorrect execution path, then and only then should you assign a hint to a query. Even in this situation, we recommend that you keep an eye on the hinted query...
Explain: Use DBMS_PREDICTIVE_ANALYTICS.EXPLAIN() to rank attributes in order of influence when explaining a target column. Predict: Use DBMS_PREDICTIVE_ANALYTICS.PREDICT() to predict the value of a target column based on values in the input data. Prediction Anomaly Function: Use the anomaly dete...
