instalação de script php em servidor

Boa tarde, seguindo a dica de um usuário do fórum, criei um plano free de hospedagem com a hostinger.com.br,

baixei o filezilla, conectei ao domínio com sucesso, e estou fazendo a transferência de um script php (são apenas 36 MB, e já se passaram 40 minutos e apenas 10 MB foram transferidos, a velocidade da minha internet é de 100 Mbps),

gostaria de saber se será necessário a criação de um banco de dados, e qual a finalidade de se criar um banco de dados para um script?

de acordo com o guia de instalação do script não será necessário a criação de um bd (o 12all referido são as 12 pastas do script):

Installation Guide
__________________

1) Unzip the .zip file.

2) Upload the main directory (the 12all folder in the zip file)
to your web server where you want to install the product. You may
change the directory name to whatever you would like on the server.

3) Adjust the file permissions on the following files:
If installing on a linux server you should
CHMOD the following files/folders to 777. Which is full read/write permissions.

If installing on a Windows server you should
ensure IIS has full control / full permissions for the following files/folders.

/12all/admin/default.authentication_db.inc.php
/12all/admin/default_engine.inc.php
/12all/cache/
/12all/cache/public/
/12all/cache/admin/
/12all/images/
/12all/images/admin/

NOTE: If you find that some of the folders listed above are missing,
this may have been caused by your compression program. All that you
need to do is add the folders to their respected directories and your
copy of 1-2-All will work correctly.

4) Run / open the install.php file located in
/12all/admin/install.php

via your web browser. Complete on-screen instructions.

That will complete your setup.

To login to your admin control panel point your browser to your
12all/admin directory.
