I want to make a database program, how can I start for?

I'm not an Access user myself, but I'd suggest starting with the Microsoft site: https://support.office.com/en-gb/art...-862f470c1a9c#

Here are two links that should be required reading before starting to build a database.

http://sbuweb.tcu.edu/bjones/20263/a...sdb_design.pdf

after reading above, then look at this tutorial

Then post back with specific issues you encounter as you begin developing your database.

Should I download a Access software on the Internet?

No - It might be free in Heaven but Access is not a free application around here, it comes as part of Microsoft Office. Go buy it or make do with the functionality available in your (legal?) copy of Excel along with writing whatever VBA code you need.

If you have acquired the Access software, then I urge you to follow this step by step tutorial to build a database to understand the mechanics. Once you have built the DB from the tutorial, you should have enough basic knowledge to apply to building your own.

If you have followed the tutorials, then you should have enough basic knowledge to start to build your db. I do not know or understand what your specific issues are. If you are looking for someone to do the work for you, then you have arrived at the wrong place. We are here to help with specific problems to get you on the right track. If you have a specific issue with the db you are building then ask away. Otherwise, we have given you all the tools you need to start the build on your own.

If in further doubt, then design a schema on a piece of paper showing your tables and fields, forms and controls. Then design your queries to gain your output. I hope this is helpful.

Go back to Crystal's tutorial and build a table in the same fashion she has shown using the normalization structure detailed in the other tutorial. Once you have your table structure built, then build your forms binding the controls on the form to your fields on the table. I cannot offer any further advise on this issue. You have the tools to build.

Access is not a free program. You have to purchase the software and license to use it.

Here is a link to purchase Access 2016. https://www.microsoftstore.com/store...ctID.323017400

Here is a link for Access 2013. https://www.amazon.com/Microsoft-Acc.../dp/B00B63E37G

I believe that 2016 is renewable each year. Not sure exactly how that works.

Please do not ask here for links to get Access for free (see Rule 11 of the Forum Rules).

If you need a database program but can't afford Access/Office, then there are free alternatives available. OpenOffice (https://www.openoffice.org/product/base.html) and LibreOffice (https://www.libreoffice.org/discover/base/), for example. They don't work exactly the same as Access, but the principles of database design remain the same.
