Désolé, je ne peux pas aider avec ça.
I think that Access is probably good for individuals who want to create a small database without it being too complex. But having developed under Access many times, I am allergic to it now ;-). For me, a company that uses Access as a database is not a serious company. Besides, it's not free. Oracle is clearly not within everyone's reach and is complicated, but MySQL works well, it's not complicated and it's free ;-).
As for the limitations (but it always depends on how you use it, for me it's more for work, so I use Oracle), Access doesn't differentiate between the types of databases (Decision-making, etc...), no stored procedures, no triggers that you can create yourself, the SQL code for making queries is very limited... and that's not all

It's surely great for individuals who want to create a simple database without it being too complex.
Yes, and it allows for a "fun" and colorful interface without having to deal with ODBC and the like (which discourages more than one individual).
But having developed under Access many times, I'm allergic to it now ;-)
I understand, I was also in overdose for a long time, but in hindsight, it still has some advantages :-)
For me, a company that uses Access as a database is not a serious company.
It depends on what it's for; if it’s to store orders in the office, within the framework of an SME, it seems suitable to me. One doesn't necessarily have to use a bulldozer to kill a fly; you don’t use a high-end drill to make holes in your sheet :-D
Moreover, I wouldn't want to denounce, but a popular French car has long been produced in England with machines monitored by Access...
MySQL runs well, it's not complicated, and it's free ;-).
Yes, but you need to install it, configure it correctly, and to create an interface, you need either a server or an external connection, which is still more complicated than the automatic forms of Access.
Access doesn't differentiate types of databases (Decision-making, etc.), lacks stored procedures, doesn't allow triggers to be made by yourself, and the SQL code for making queries is very limited... and I could go on.
True, but not all databases necessarily need that... But for powerful databases, that’s definitely a choice I wouldn’t make :-D

Although in this range I would rather advise VFP, it must be acknowledged that Access is a remarkable product when you know how to talk to it (I am referring to Access <=97).
For small businesses or small applications, it's even a pure marvel, especially for companies that cannot afford to pay a developer and do things a bit manually.
However, it’s expensive for what it is.
Access has limitations, that's obvious. But many qualities as well. Not everything that comes from MS is necessarily bad, and even a non-programmer can quickly get into it and achieve their goals. It’s a pleasant and intuitive product.

Thank you FINALLY to HDU for simply answering the question, rather than spreading his "knowledge" like teebo who only criticizes the questions of others. Indeed, weena's question was not clear, but is that a reason to criticize the technical solutions he uses? Do you think you need to set up a SQL server to manage a DVD collection or a wine cellar?
=> What a bad spirit!

Hello.
You are right.
What a bad spirit. One of those young roosters without experience? I think so.
He will calm down with age.
In any case, thank you for the limitations, I was teaching a course to users on the different databases and their advantages and disadvantages, I got all the Access limits "in one shot."
Moreover, I agree with all the people who responded, you should not try to manage a small business the same way you would manage a multinational.

What are the most efficient servers?
Oracle on Apache in Linux
Mysql on Apache in Linux
Alright, I need to find the link to that study (I think it was on mysql.com before Microsoft requested to remove the statistics for servers on Windows that were not at the top of the list (I wonder why ...... lol
In that case, why bother using Access with a Windows server?
Linux, php, mysql is a solution that works very well and is used by many sites.
Personally, I use php, mysql, apache in my work and mysql is easy to use with the phpmyadmin tool.
And yes, I have used Access in the past. IF I were to use Windows (the if is important) I would probably look towards other solutions like mysql server or others ....

It's simple, Access next to MySQL or better ORACLE => Access isn't worth a penny ;-)
In short, Access is for beginners and even then, they will be traumatized by databases afterwards.
(PS: You will notice the use of uppercase letters on the database names which clearly defines my thoughts)

Well, I think you're hasty in your judgment... Access is the appropriate tool for a small local database, much more than Oracle...
I've even run a network application on Access when response time was a limitation, and it ran without any problems for years...
To answer the initial question as I understand it (size limitation of a database in Access), I can tell you that I've seen databases of several gigabytes (2 :-D) in Access97. To my knowledge, they didn't have any issues with it, but I wasn't there when my database reached that size...
