whenever i'm on a project and see a mismatch in the names in the database, the back-end and the front-end i immediately get the urge to kill everyone. > The part before the $ is actually a company name and it turned out this database has the same tables for 23(!) companies, and some other (un?)related tables, giving the database a staggering 41,000+ tables! that's like creating 150+ tables a day for an entire year. part of those tables are created dynamically? abandon project

I think it's the product of years of development and dynamic table creation, possibly created by a user directly from the product. But I'm not sure.

Because I don't like a database I have to access once? Would be very bad for my finances :rolleyes:

I once got to look into the table and variable name structure of BPCS. It, too, was a nightmare, and I can't believe it was a successful commercial venture. It might not have been as bad as the one you looked at. I don't know, because I cussed and closed it as soon as I could! :laugh:

I always wonder about that too. Not because the database is a mess, because users can't care less about that, but because if the database is a mess then it's likely that everything else is a mess too. Maybe it's just this weird naming that's wrong with it, maybe the naming was generated by some tool, but the developers actually know what they're doing? :confused:

No challenges here. Another company owns the database, someone else sometimes works with it. That someone else asked me if I could do him a favor and write that query. Other than that the database is not used anymore and kept around for historical data. I've got other (fun) challenges coming my way :D

Had to write some query on a SQL Server database today. Opening the database took close to a minute. What I saw then will forever haunt me. Table names like [01 Some Company & Partner l.l.c.$Customer Ledger item], but also [01 Some Company & Partner llc$Cust something else], because sometimes you need Customer while other times you simply need Cust. Each table had columns with names like [Entry No_], [Customer report code 1] and [Amount (CNY)] (CNY apparently means "currency", but with column names like that why even bother to abbreviate?) :sigh: So we've got names with spaces, dots, numbers and symbols, complex enough to pass a password complexity validation! Now there's something particularly odd about the table name... The part before the $ is actually a company name and it turned out this database has the same tables for 23(!) companies, and some other (un?)related tables, giving the database a staggering 41,000+ tables! :wtf: So let me say this again so you can be sure you read it right and I spelled it correctly... OVER FORTY-ONE THOUSAND TABLES! :wtf: It was a bit over 1700 tables per company, which I already think is A LOT, combined in a single database. SQL Server allows for int.MaxValue objects in a single database and I have a feeling this application was pushing the limit (if not, not for lack of trying) :laugh: I'm assuming most of it is generated, but even then, WHY WOULD YOU GENERATE SUCH !G($#&#$(!#F:elephant:J!#(P!? :mad: Sometimes you think you've seen it all and then you run into something like this and realize there really is no limit to human stupidity :sigh:

Probably not intended, but this sounds like a great way to be GPDR compliant - each table can have different access controls so that someone who is allowed to view the data for $COMPANY_A will never be allowed to view the data for $COMPANY_B. Unintended consequences, and all that...

And I'll bet some company tables are unique so combining them will be a challenge. I made a tidy living in the 90's attempting to normalise such horrors, never quite that big and ugly though. I wonder if the original was converted from MS Access, it is definitely an end user built database. So quote a rate and don't offer a time frame (or even a guarantee) if you are going to try and clean it up. PS CNY is definitely the Chinese currency.

No doubt, luckily there's no need to combine them :D Hopefully I'll never see this database again :laugh:
Mycroft Holmes wrote:

Don't think so, end users here are typically as a-technical as they come. I think a lot of it was generated though. The database is owned by another supplier and kept around for historical purposes, I don't think it's actively being used anymore.
Mycroft Holmes wrote:

Nope, it's short for CurreNcY :laugh: The amount in the column is usually the same as that in the regular amount column, except when the customer is not a Euro country. This supplier doesn't do anything with China specifically.

Already did that years ago for another project, and both my customer and I are still reaping the benefits ;)

I'm afraid I have been there, just not with so many tables (maybe 20) nor companies (only 3), and using MySQL. I just made a "SQL template" script and separated the companies into separate databases. Any common change would be made to the template and would be inherited by all (when the script was run against each of the databases). But I guess they have to justify buying new hardware when their queries are not fast enough. Hey, at least those have their queries in the database, right? Right?! In my case they were doing all queries (even simple ones like "select * from tableA where userID=x") in a weird PHP backend because they claimed that "the database is not good enough to filter the tables the way we want it" :wtf: Anyway, I think some whipping is in order. Grab your whip and get the guy that wrote that database. Don't let him procreate more databases like that :mad: :-D

Yeah, it's probably to keep one company out of the other's data, but giving them separate databases may have been a better option... Also, I'm not sure if GDPR applies to businesses (it's all B2B) ;)

Because the unsupervised junior devs thought multi-tenant tables were too much work for the prototype, and when it needed to scale out management balked at paying for one database/customer or a major refactor of the tables to do multi-tenant the sane way so the juniors -still without any meaningful supervision - came up with a WTF pattern.

Why go deep, when you can go wide? If each company has its own set of tables dedicated to it, think of how much faster queries are gonna run than if all the data for all companies was combined... I'm sure that was the line of reasoning...
