Answer:
It is a process that extracts information from internal and external databases, transforms it using a common set of enterprise definitions, and loads it into a data warehouse.
Explanation:
Extraction, transformation, and loading can be defined as a process that extracts information from internal and external databases, transforms it using a common set of enterprise definitions, and loads it into a data warehouse.
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

1.Two robots start out at 426c cm. apart and drive towards each other. The first robot drives at 5 cm per second and the second robot drives at 7 cm. per second. How long will it take until the robots meet?
In your response below, please answer each of the following questions:
a. What is the question being asked?
b. What are the important numbers?
c. Are their any variables?
d. Write an equation.
e. Solve the equation.
f. Do you think your answer is reasonable? Explain.
Answer:
a. The time it will take for the two robots meet
b. The important numbers are;
426 (cm), 5 (cm/second) and 7 (cm/second)
c. Yes, there are variables
d. The equation is 5 cm/s × t + 7 cm/s × t = 426 cm
e. The solution of the equation is, t = 35.5 seconds
f. Yes, the answer is reasonable
Explanation:
a. The question being asked is the time duration that will elapse before the two robots meet
b. The important numbers are;
The distance apart from which the two robots start out, d = 426 cm
The speed of the first robot, v₁ = 5 cm/second
The speed of the second robot, v₂ = 7 cm/second
c. The variables are;
The distance apart of the two robots = d
The speed of the first robot = v₁
The speed of the second robot = v₂
The time it takes for the two robots to meet = t
d. The equation is;
v₁ × t + v₂ × t = d
Plugging in the known values of v₁, v₂, we have;
5 cm/s × t + 7 cm/s × t = 426 cm...(1)
e. Solving the equation (1) above gives;
5 cm/s × t + 7 cm/s × t = t × (5 cm/s + 7 cm/s) = t × 12 cm/s = 426 cm
∴ t = 426 cm/(12 cm/s) = 35.5 s
t = 35.5 seconds
f. The time it would take the two robots to meet, t = 35.5 seconds
The answer is reasonable, given that the distance moved by each robot in the given time are;
The distance moved by the first robot, d₁ = 35.5 s × 5 cm/s = 177.5 cm
The distance moved by the second robot, d₂ = 35.5 s × 7 cm/s = 248.5 cm
d₁ + d₂ = 177.5 cm + 248.5 cm = 426 cm.

name the statement which is used at end of each case from computer subject
(plz answer fast and correct i will mark as brainlist ......)
Answer:
In computer programming, a statement is a syntactic unit of an imperative programming language that expresses some action to be carried out.[1] A program written in such a language is formed by a sequence of one or more statements. A statement may have internal components (e.g., expressions).
Many programming languages (e.g. Ada, Algol 60, C, Java, Pascal) make a distinction between statements and definitions/declarations. A definition or declaration specifies the data on which a program is to operate, while a statement specifies the actions to be taken with that data.
Statements which cannot contain other statements are simple; those which can contain other statements are compound.[2]
The appearance of a statement (and indeed a program) is determined by its syntax or grammar. The meaning of a statement is determined by its semantics.

Using more than one array to store related data is called _____________ arrays.
Answer:
Using more than one array to store related data is called parallel arrays.
Explanation:
I just did it and got 100% on the quiz
Using more than one array to store related data is called parallel arrays.
What is array?An array is a type of data structure used in computer science that holds a set of elements that are all uniquely recognised by at least one array index or key.
An array is stored in a way that allows a mathematical formula to determine each element's position given its index tuple.
In parallel arrays, a collection of data is represented by two or more arrays, where each corresponding array index represents a field that matches a particular record.
For instance, the array items at names and ages would explain the name and age of the third person if there were two arrays, one for names and one for ages.
Thus, the answer is parallel array.
