3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)

4. DELETE FROM planes WHERE Tailnum = 'N15501'

Explanation:

1. SELECT * FROM planes

To select all from a table, use select * from [table-name]. In this case, the table name is planes

2. UPDATE $planes\ SET$ YEAR = 2013 WHERE year IS NULL

To do this, we use the update query which is as follows:

UPDATE [table-name] SET [column-name]= [value] WHERE [column] IS NULL

So: the above query will update all YEAR column whose value is NULL to 2014

3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)

To insert is very straight foward.

The syntax is:

INSERT INTO [table-name] (column names) VALUES (values)

4. DELETE FROM planes WHERE Tailnum = 'N15501'

To do this, we use the update query which is as follows:

DELETE FROM [table-name] WHERE [column] = [value]

So: The above query will delete the entry in (3) above

Nookie1986 [14]

Answer:

c. Service oriented architecture (SOA)

Explanation:

In a service oriented architecture (SOA), a component of an application provides services to other components of the application or other applications majorly via a communications protocol over a network. In other words, SOA is a programming or software development technique in which services communicate with each other across different platforms.

One key principle of SOA is to design an application (which in itself is a piece of software with multiple features) that is independent of any product, service, vendor or technology but can be integrated into other applications. SOA makes use of loose coupling - a technique in which a client service remains independent of another service that requires it.

In contrast, a monolithic architecture aims at developing a software that is self-contained, independent and not to be integrated into other applications.

On another hand, Software as a service (SaaS), though a bit similar to SOA, is a model in which an application is made available to customers basically through a network. Users basically access the application via a browser.

Therefore, the best option is

C. Service oriented architecture.
