Kunci Jawaban Oracle

The explanation below can be an example of which constraint type? 3. The explanation below can be an example of which constraint type? 5. Why would this table name NOT work in an Oracle database? Table names must start with an alphabetic character. It is too long. None of the above. 7. The conceptual model is changed into a physical model.

The physical implementation will be a relational database. 9. Two entities A and B come with an optional (A) to Mandatory (B) One-to-One relationship. Both furniture A and B get a new column and a Foreign Key. Nowhere, One-to-One romantic relationships are not changed. 10. Relationships on an ERD can only just be changed into UIDs in the physical model? 11. The Oracle Database can put into action a many to numerous relationship. You create two foreign secrets between your two tables simply.

  • Which of the following kinds of organization blends elements of partnerships and corporations
  • Platform deals to get application developers to develop for your platform
  • Look for grammatical errors and add links
  • 17 purchase goods in cash 10000
  • You or another admin recently changed your Page’s name (details below)

13. An “Arc Implementation” can be carried out just like every other Relationship – you merely add the required Foreign Keys. 14. Which of the next is a justification for considering a Subtype Implementation? Business functionality, business rules, gain access to paths, and rate of recurrence of access are all very different between the subtypes.

The resulting table shall reside in a single database and be used by just ONE user. The normal access paths for the supertypes will vary. Most of the relationships are in the supertype level. 15. When translating an arc relationship to a physical design, the arc must be converted by your relationships into foreign tips. What additional steps should you take with the created foreign keys to ensure the exclusivity principle of arc relationships? 1. When translating an arc romantic relationship to a physical design, you must change the arc associations into foreign tips. What additional steps should you take with the created international keys to ensure the exclusivity basic principle of arc associations?

The common gain access to pathways for the supertypes are different. The resulting table will reside in a single data source and be used by just ONE consumer. Business efficiency, business rules, gain access to paths, and rate of recurrence of access are very different between the subtypes. Most of the relationships are at the supertype level.

3. When mapping supertypes, human relationships at the supertype level transform as normal. Relationships at subtle level are implemented as foreign secrets, however the international key columns become obligatory. TABLE not work as a table name? The data source does not understand all capital characters. TABLE is a reserved phrase. There is absolutely no problem here.

Object names must not start with a number. They must begin with a notice. 5. In an Oracle data source, why would the next table name not be allowed ‘EMPLOYEE JOBS? 6. Why would this table name NOT work in an Oracle database? Table names must begin with an alphabetic personality.

It is too much time. None of the above mentioned. 9. When an Ark is transformed to the physical model every romantic relationship in the Arc becomes a required Foreign Key. 10. The Oracle Database can put into action a many to many relationship. You merely create two international keys between your two furniture. 13. The reason below is an example of which constraint type?

Only one column that must definitely be null. A single column that identifies each column in a table uniquely. A number of columns in a table that uniquely identifies each row in that table. A couple of columns in one table that uniquely identifies each row in another table. A single column that uniquely identifies each column in a table. A number of columns in a desk that uniquely identifies each row for the reason that table.

Only one column that must be null. A couple of columns in one table that distinctively recognizes each row in another desk. 5. When mapping supertypes, romantic relationships at the supertype level transform as usual. Relationships at subtle level are implemented as foreign keys, but the international key columns all become necessary. 6. When mapping supertypes, interactions at the supertype level transform as usual. Relationships at the subtype level are implemented as foreign keys, however the foreign key columns become optional.
