Use semaphore(s) to solve the following problem. There are three processes: P1, P2, and P3. Each process Pi has a segment of cod

Lisa [10]

Answer:

See explaination

Explanation:

Here we will use two semaphore variables to satisfy our goal

We will initialize s1=1 and s2=1 globally and they are accessed by all 3 processes and use up and down operations in following way

Code:-

s1,s2=1

P1 P2 P3

P(s1)

P(s2)

V(s2) .

P(s2). .

. C2

V(s1) .

P(s1)

. . C3

V(s2)

Explanation:-

The P(s1) stands for down operation for semaphore s1 and V(s1) stands for Up operation for semaphore s1.

The Down operation on s1=1 will make it s1=0 and our process will execute ,and down on s1=0 will block the process

The Up operation on s1=0 will unblock the process and on s1=1 will be normal execution of process

Now in the above code:

1)If C1 is executed first then it means down on s1,s2 will make it zero and up on s2 will make it 1, so in that case C3 cannot execute because P3 has down operation on s1 before C3 ,so C2 will execute by performing down on s2 and after that Up on s1 will be done by P2 and then C3 can execute

So our first condition gets satisfied

2)If C1 is not executed earlier means:-

a)If C2 is executed by performing down on S2 then s2=0,so definitely C3 will be executed because down(s2) in case of C1 will block the process P1 and after C3 execute Up operation on s2 ,C1 can execute because P1 gets unblocked .

b)If C3 is executed by performing down on s1 then s1=0 ,so definitely C2 will be executed now ,because down on s1 will block the process P1 and after that P2 will perform up on s1 ,so P1 gets unblocked

So C1 will be executed after C2 and C3 ,hence our 2nd condition satisfied.

Define the following terms: data model, database schema, database state, internal schema, conceptual schema, external schema, da

PolarNik [594]

Answer:

Following are the solution to the given terms:

Explanation:

Data Model: A set of concepts that are ideal for describing the layout, computational tools, relations, semantics, constraints on accuracy.

Database Scheme: It is also known as the overall design of the database.

Database State: It is the data in the database at a particular moment in time.

Internal Schema: The physical structure of the database is defined.

Conceptual Schema: It hides the details of physical storage.

External Schema: It describes the part of the database the user group sees. In other words, we can say that it is a view of the database.

Data Independence: The ability to modify the schema at a single level while modifying the schema at a higher level is often recognized.

DDL: It stands for the Data Definition Language, which is used by DBA and dev use for creating With particular scheme.

DML: It refers to the Data Manipulation Language, which is used to manipulate, add, recover, insert, remove, and alter data.

SDL: It stands for the storage definition language, in which the internal schema of the database is applied for storage description.

VDL: The view definition language specifies the user to view and mapping their conceptual schema.

Query Language: It is just an independent, dynamic, high-level dialect used during manipulation.

Host Language: It is also the machine language, that would be incorporated into the general programming language by low-level data handling commands.

Data sublanguage: It uses for embedding in the last language.

Database Utility: It is a program, which helps to handle the database with DBA's modules.

Catalog: The entire structure and constraints of the database is defined.

client/server architecture: The design of the database server system that device usability: model user, model server (landless storage) software Government computer design in which many users (remote processors) demand a central server to receive service (host computer).

Three-tier architecture: It is the application, data, user interface.

n-tier architecture: multiple levels. The nth level must only be able to handle the n+1 application and transmit it to the n-1 point.
