<h2>Answer:</h2>

A <u>pipeline</u> is several programs simultaneously processing the same input/output stream.

<h2>Explanation:</h2>

It is the data processing elements set (functions, processes, threads) in chain, series connection where output of one element is input of the other. Its analogy is similar to physical pipeline. Some buffering is allowed between consecutive elements. The information flowing through the pipeline is a stream of bits, bytes, records.

This can be one-directional and bi-directional. These are frequently implemented in multitasking Operating Systems, many processes are launched at same time.

Write the SQL statements that define the relational schema (tables)for this database. Assume that person_id, play_id, birth_year
Sunny_sXe [5.5K]

Answer:

  • SQL statement that defines table for Actor

CREATE TABLE Actor(

person_id integer primary key,

name varchar2(40) not null,

birth_year integer check ((birth_year) <= 2019)

);

  • SQL statement that defines table for Play

CREATE TABLE Play(

play_id integer primary key,

title varchar2(60) not null,

author varchar2(60) not null,

year_written integer check ((year_written) <= 2019)

);

  • SQL statement that defines table for Role

CREATE TABLE Role (

person_id integer,

character_name varchar2(60) not null,

play_id integer,

constraint fk_person foreign key (person_id) references actor(person_id),

constraint fk_play foreign key (play_id) references play(play_id),

primary key (person_id, character_name, play_id)

);

Explanation:

Other information that were not added to the question are as below:

The following database contains information about three tables i.e. actors, plays, and roles they performed.

Actor (person_id, name, birth_year)

Play (play_id, title, author, year_written)

Role (person_id, character_name, play_id)

Where: Actor is a table of actors, their names, and the year they were born. Each actor has a unique person_id, which is a key.

Play is a table of plays, giving the title, author, and year written for each play. Each play has a unique play_id, which is a key.

Role records which actors have performed which roles (characters) in which plays.

Attributes person_id and play_id are foreign keys to Actor and Play respectively.

All three attributes make up the key since it is possible for a single actor to play more than one character in the same play

Further Explanation:

In SQL, in order to define relational schema (Tables) for a database, we use CREATE TABLE statement to create a new table in a database.  The column parameters specify the names of the columns of the table.  The datatype parameter specifies the type of data the column can hold (varchar, integer, date)
