However, the JDBC-ODBC bridge -- or JDBC Type 1 driver -- should be viewed as a transitional approach, as it creates performance overhead; API calls must pass through the JDBC bridge to the ODBC driver, then to the native database connectivity interface. In addition, it was removed in ...

In Oracle Database 12c, if histogram creation is requested or the database decides to create a histogram, Oracle Database first generates the top frequent values (TFVs) and then it decides which type of histogram should be created. It is obvious that if the number of distinct values (NDV)...
When safety is FULL, the principal first enters the SYNCHRONIZING state and as soon as it synchronizes with the mirror, both partners enter the SYNCHRONIZED state. When safety is OFF, the partner databases start with the SYNCHRONIZING state. Once the mirror has caught up, the state goes to ...
Cloud data warehouses.First developed to provide data warehousing capabilities for business intelligence and reporting applications, cloud data warehouse and DWaaS technologies typically now also supportdevelopment of data lakesthat contain large amounts of raw data, as well as machine learning and other...
Your application changes Nancy Buchanan's status to "Preferred." As a result of this change, the value of theRowStateproperty for that row changes fromDataRowStatetoDataRowState. The value of theRowStateproperty for the first row remainsDataRowState. The data table now looks like this: ...
