Answer:

columns, rows

Explanation:

In Computer programming, a atabase schema refers to the logical design of the database while the database instance refers to a snapshot of the data found in a database at a given instant in time.

Basically, in database management, the term "schema" is used to denote a representation of data while the term "instance" is used to denote an instance of time.

A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.

Also, a database instance is a snapshot of the data in the database at a given instant in time and as such represents an operational database by following the conditions, validation and constraints set for a database management system.

These data can be stored or organized in a database management system through the use of multiple-column record formats.

In a multiple-column record of a data file, columns represent different variables and rows represent different cases (respondents) such as experimental data, independent observations etc.

Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

Cloud computing comprises of three (3) service models and these are;

1. Platform as a Service (PaaS).

2. Infrastructure as a Service (IaaS).

3. Software as a Service (SaaS).

Software as a Service (SaaS) can be defined as a cloud computing delivery model which involves the process of making licensed softwares available over the internet for end users on a subscription basis through a third-party or by centrally hosting it.

Hence, Software as a Service (SaaS) is an example of a cloud computing environment that provides users with a web based email service. Therefore, if you pay a subscription fee to use an application via the internet rather than purchasing the software outright, the app is called a Software as a Service (SaaS) application.

Some examples of SaaS applications are Salesforce, Google apps, Bigcommerce, Dropbox, Slack etc.

Marta_Voda [28]

Answer:

a) Global

Explanation:

The scope of a variable declared outside of any function is Global.

Let us consider an example:

int g;

int add(int a,int b){

return a+b;

}

int subtract(int a,int b){

return a-b;

}

Here the variable g is defined outside any function and is accessible anywhere within the program. This is a global variable.

Variables defined within each function - a,b on the other hand have a local scope are are visible only within their respective function bodies.
