- Which of these statements is true about relation partitioning? It places different rows from the same table on different machines, allowing for the computing of different query predicates in parallel on different machines. It places different columns from the same table on different machines, which allows for computing different query predicates in parallel on different machines. It places certain tables on one machine and others on a different machine, allowing different query subexpressions in the same plan to be computed in parallel on different machines. It replicates and indexes data, which generally improves query performance.arrow_forwardTask 1: The InstantRide Management team founded a new team for car maintenance. The new team is responsible for the small maintenance operations for the cars in the InstantRide system. The main idea is to take actions faster and minimize the time spent for the maintenance. Therefore, the Car Maintenance team wants to store MAINTENACE_TYPE_ID (char(5)) and a MAINTENANCE_TYPE_DESCRIPTION (varchar(30)) in the database. Using MAINTENANCE_TYPE_ID as the PRIMARY KEY, create a new table, MAINTENANCE_TYPES, and send the table description with the column names and types to the Car Maintenance team.arrow_forwardUsing the World database, two updates are needed for one row in the City table. The city of Giumri in Armenia (country code ‘ARM’) is spelled incorrectly in the table. It should be spelled ‘Gyumri’. Also, the district is currently ‘irak’ in the table and should be ‘Irak’. Make these changes in one construct.arrow_forward
