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.
Answer:
the subject of the message
the sender's name
the recipient's name
the date and time when the message was received
Explanation:
Various information is displayed in the header of the message of a received message. And they are the subject of the message, which briefs what is there inside the message. And it mentions the sender's name as well as the recipient's name, and finally, the date and the time as well are stated that explains exactly when the message was being received. And all this information is shown in the header of the message.
Well we just benefit from it like it just helps as I guess
Answer:
Single quotes; Double quotes
Explanation:
Character literals is a type of literal in Java programming used for denoting constant valued character. Examples are 'g', '6', 'A' '+' etc.
String literals is a type of literal in Java programming used for representing or displaying of a sequence of characters or string values. Examples are "Hello Brainly user"
In Java programming, Character literals are enclosed in single quotes, string literals are enclosed in double quotes.
The best way for an end user to visualize a highly complex 3D model using a Virtual Reality headset is to: A) use any headset and increase the bandwidth of the Wi-Fi connection.
<h3>What is Virtual Reality (VR)?</h3>
Virtual Reality (VR) can be defined as a computer technology through which virtual images of any physical environment (realities) and human-machine interactions are displayed, especially through the use of various computer technologies and wearables.
<h3>The elements of Virtual Reality (VR).</h3>
Some of the elements of Virtual Reality (VR) include the following:
In this context, we can infer and logically deduce that Virtual reality is a computer technology which is designed and developed to simulate a three-dimensional (3D) environment through which end users can explore and interact.
In conclusion, the best way for an end user to visualize a highly complex three-dimensional (3D) model using a Virtual Reality headset is to use any headset and increase the bandwidth of the Wi-Fi connection.
