Maslowich

Answer:

We can use CREATE command to create tables with columns having descriptive names

Explanation:

Firstly, create a table using CREATE  command in SQL. The syntax is as follows:

CREATE TABLE [table_name]

(

 [col_name] [datatype]),

[col_name] [datatype]),

[col_name] [datatype]),

[col_name] [datatype])

)

Once the table is created, we can insert the data into table using INSERT command. It's syntax is as follows:

INSERT INTO table_name VALUES('', '', '')

if datatype is string, values must be entered within single quotes. If datatype is int, values are entered directly without using  quotes.

Now, you can select the data from  the table using SELECT command. It's syntax is as follows:

SELECT column-list FROM table_name

If you want to filter rows according to conditions, you can use WHERE command.

I have created  sample table and inserted some data into it. Now, I applied some queries on it to select data from the table.

I have written in a text file and attached the same. Please find. Thank you!

What is workflow? how do you create your own workflow?
lana66690 [7]
A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, provide services, or process information.


Create a detailed outline of what you want to achieve and sketch a workflow diagram before using workflow chart software or templates. This will help to ensure your chart is accurate and complete. Always consider your process and workflow manageability when inserting logic in your workflow chart. You can use decision symbols, connectors and text boxes. Always confirm the accuracy of your workflow chart with other stakeholders.


(If you need to know what the workflow diagrams layout is just look it up. GL.)

3. Polymorphism

4. Data hiding/ encapsulation

Classes and objects depict the major component of the OOP (object oriented programming). It explains the object like a ball in a soccer game development.

The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.

In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.
