Oracle Database API for MongoDB The new Oracle Database API for MongoDB enables developers to use MongoDB APIs with Oracle Autonomous Database, including Autonomous JSON Database. The API allows you to develop and run MongoDB based applications using MongoDB tools, drivers, and frameworks directly with Autonomous Database. You can run SQL and PL/SQL that you know and love over your JSON data. You can also integrate machine learning, graph or spatial analytics, among others, into their applications—all within the Autonomous Database. Existing MongoDB applications can be migrated and run on OCI unchanged, giving you an easy way to finally get your applications running on Autonomous Database. |

Let’s check your knowledge with a sample question You execute these statements:
|
|
|
|
create table qz_bricks (brick_id integer not null primary key, colour varchar2(10) not null, shape varchar2(10) not null);
insert into qz_bricks values ( 1, 'red', 'cylinder' ); insert into qz_bricks values ( 2, 'blue', 'cube' ); commit;
create view qz_bricks_v as select * from qz_bricks where shape = 'cylinder' with check option; |
|
|
|
Which choices run a DML statement against the view that complete successfully (without error)?
1) insert into qz_bricks_v values ( 3, 'green', 'cylinder' ); 2) insert into qz_bricks_v values ( 4, 'yellow', 'cube' ); 3) update qz_bricks_v set colour = 'blue' where brick_id = 1; 4) update qz_bricks_v set shape = 'cube' where brick_id = 1; 5) delete qz_bricks_v where shape = 'cube';
