Hello、munejyuka。

I sometimes see and hear、

database

the term。

What exactly is this database?

Even if you ask me to explain, I can't...

 

that's why、I thought it would be good to know at least the minimum, so I looked into it.。

 

 

What is a database?

What is a database?、

 

extract data、edit、Collected for easy sharing

 

apparently。

It says that something that simply collects data cannot be called a database.。

 

For example、

 

・I want to extract only products with sales above a certain level from a product list.

・From address book、I want to list only people living in Osaka Prefecture.

・From the contract list、I want to extract only Mr. Yamada's customers.

 

Databases are useful in situations like this.。

 

 

Database type

There seem to be different types of databases.、There are three main types。

I'll summarize it briefly.。

 

・Hierarchical database：Associate and save data like a tree

・Network database：Connect and store related data

・Relational database：Save data in a table format like Excel

 

If I start looking into it, it will probably last forever.、I'll just give you a quick overview。

Creating a database that suits your purpose、I think this will affect the feeling of use afterward.、I feel that we need to deal with it on a case-by-case basis.。

 

 

Summary

・A database is not just a collection of data.

・Databases store data in a fixed format.、Made easy to use

・Hierarchical type、network type、There are three types of relational types

 

If the database is in order、Now you can quickly find the data you want、You can improve work efficiency and reduce burden in various situations.。

 

What really matters is、Rather than collecting data、It's about making good use of the database and getting good results.、We need to keep this in mind and take action!

 

To everyone、I hope you can understand a little bit more about databases!

 

Please read to the end、Thank you!
