This sounds like it easily could be done with something like an Arduino (or raspberry pi) to read the barcode and open the gate, and it would just send a POST request to some endpoint that would log in a database. That way the reader is decoupled from your database through a REST API, and you can use whatever language you like for the API interface.

IT have no problem understanding the need for patching an OS, migrating to a new OS, upgrading old hardware etc, etc. But often fail to understand the need to do the same with everything custom built they manage.
So getting a bespoke solution is not a one-time project or a one-time expense. Software needs to be taken care of from the cradle to the grave. As the OS is updated, packages deprecated, frameworks have become obsolete, etc - the software needs to be updated as well. Even if no new functionally is added or removed.
This is also come of the consideration that goes in to selecting what technology to use.
Really? This is not an IT issue, but likely generally more a company/business issue. The chances that IT is what is preventing a rewrite are damned near zero - why do I say this - because it's not an IT spend, or at least shouldn't be viewed as an IT spend. This is a production spend - This solution is specific for something in production - no different than a million dollar printer is in a printing shop. They don't want to replace those printers anymore than they want to replace solutions like this OP is asking because production doesn't want to spend money on it.
It's likely that IT would LOVE to see this shit upgraded to modern solutions, making them possibly more reliable, or at least modernly fixable. -

It's IT that is responsible for making their internal customer understand that there needs to be yearly maintenance costs on their custom software. Just as you would have with any software licensing or service agreement. There is no technical difference between software that the company themselves have commissioned and software that is stock from Microsoft, Oracle, vmWare or whoever.
It's because IT fails at this, they end up with a mess after X number of years. Because each year the software will get more and more out of date. Eventually it will prevent IT from running the latest OS, or updating the database or similar.
And I'm not talking about big upgrades or complete changes to the functionality. I'm talking about maintenance - keeping it working the same while the OS is updated, the database is updated, the software library/APIs/frameworks/whatever are changed.
I'm sure that there are companies that have this figured out and understands that they of course are responsible for keeping their own software current. I just haven't seen it much except in situations where it happens naturally. For instance when new functions are added.

Oh yes there is - there's nothing in the law requiring it. At lease with the licensing model, if they want to continue getting support/updates, they pay.
Granted same is true here - but as you said, I'm sure that the business was aware of this when they commissioned the project. Don't simply blame IT for this not happening - again, they likely don't control the purse strings in either of the above cases. -
@pete-s I'm not sure why you're blaming IT here.
It's bespoke software - IT didn't create it - some dev team, internal or not did (at least that's what we assume). If it's an internal team, then it's fully on them for not maintaining their software - i.e. providing updates to IT to install.
If it's an external team, then it's on the company for not listening when IT told them they need to hire someone to maintain it coding wise.You're what - assuming IT just didn't mention to management that it needs yearly updates/etc? Well, if that's true, then some of the blame belongs to IT, but some is still on the manager/owner because they aren't considering their business holistically.

Yes, I'm assuming IT didn't mention it because they didn't think of it - as it's not immediately obvious to everyone.
If they did mention it and management decided against it, then it is what it is.

A full life cycle of the device/solution should be undestood when implementing.. if not, you've already failed.
Granted, nothign says you have to stick to that.. but at least there's an understanding up front.

This is where the lay person (and myself included at times) gets totally wallooped. The lay person has no idea what's needed - they only know they have a problem and want it fixed...
Exactly, even pretty seasoned IT departments may have little to no knowledge of what is needed here. IT should know that software engineering is needed. But beyond that, there is nothing in the IT realm that should help.
Sure, IT should know something about database options and that SQLite is likely their preferred solution for lots of reasons (I know IT should know this because it's in the book I just wrote last week, lol.) But will SQLite handle the data best for the application? IT can't know that, because IT doesn't know how the software is written, what drivers are used by the framework, and so forth. IT can't know enough to be useful. Not doesn't, but can't.
None of the decisions, like language, database, framework, hardware, etc. can be talked about individually, it's one large decision that has a lot of factors. So talking about them before the engineering team is engaged might be interesting, but pointless.
I agree with everything you say.
Wearing my software engineering hat, there is another dimension to this as well. IT should understand, but for some odd reason seldom do, that custom software has a life cycle too.

Totally agree. But I've never personally seen IT fail at this. I've seen companies fail at this constantly, but never their IT people. I'm sure IT does miss this boat sometimes.
But my experience is that IT gets bypassed, the unsupported "ghost ship" software is handed to them and IT gets stuck with already abandoned software to deploy.

This is why I'm confused a little I guess...Both yourself and Scott reference having software engineering knowledge/background, and you even said up above in your response to the original post that you've done many similar custom projects (probably close to 100), but then then you give no info such as we tend to use MariaDB and python, or we find that this combination has worked really well for us in our similar projects, etc. Instead you give him the info that he should talk to a software engineer, but here two software engineers are telling him to talk to a software engineer.
Right. Until we have ALL the details, giving any details would be worse than useless, because they might be misleading. Saying that Python and MySQL work for this often isn't useful beyond just a point of interest. To actually know what is needed, a software team needs to look at all of the requirements and the full scope of the picture (deployment needs, lifecycle needs, support needs, IT capabilities, political aspects, and on and on) and determine what is right. Nothing we suggest could be useful here.
This is different from an IT project where you, and IT pro, might say "Hey SAM, I have a project and was just wondering what you thought a good starting point for research might be." Because in our case, doing this with IT, you and I both have a full scope understanding of how to research the need, and that my advice should be thrown away the instant a new variable is discovered.
Doing the same with software to a non-software person just introduces the risk that the advice will be used in some way and there is no way to use it. Knowing that Python is perfect 99% of the time is terrible knowledge unless you are prepared to evaluate when you are the 1%. No matter what we say, the engineering team that will actually do the work as to do a full evaluation. A partial evaluation has no utility at all.
So it is basically all or nothing and we are opting for nothing, because pretending we can give advice based on what is here is misleading and wrong.
That said, example technology would be super simple and I can list lots of options. There are many potential ways to go with the project.
What is much easier, though, is ruling out (or nearly ruling out) technologies that would essentially never make sense like Java, VB, COBOL, Fortran, ADA, Forth, SmallTalk, LISP, MS SQL Server, Access, Oracle DB, IBM DB2, etc. Products that have no real possibility of fitting any bill regardless of the requirements unless the requirement is 100% political like "screw any and all evaluation and use X because I said so", at which point, no engineering advice is useful.

The end user has no place to turn other than us-- without embarking on a search they have already decided would be better for their IT company to tackle.
Nothing wrong with that, IT overseeing software engineering is generally better than any other department doing it unless the CEO takes it on directly (which is where it should go, engineering should report at the same level as infrastructure typically.) Chances are no other department has the ability to oversee outsourcing something complex. That it is software is not really relevant. Could be any complex activity that is outside of the norm for some other department. IT tends to be the most well rounded.

Continuing this topic appears to be more wasteful of my time than looking to the other sources we have available to us.
There are software engineering resources here, but we'd have to get into all details in order to provide additional guidance. I think from the 10K foot view, you have what there is to have. It's enough to engage a software firm at this point, for sure. There's really no step between this and that.

This is something the company I work for could possibly do. But I have no way to make any kind of intelligent conversation in forums posts without asking all of the questions I asked, then having you answer, then me asking more questions.
You did answer my questions, so now it is on me again.I just looked, for kicks...... The whole packages was written in 2006 with one modification in 2009 (running untouched since) and is 498 lines of VBA code plus one canned serial comms module.
We're talking super simple. I kinda wish I had 5 hours to dump into it. Heck REXX and a flat file read into an array would be perfect.
Often, if you have the dev resources, this kind of stuff is a weekend project to "do it right." Without digging into it, can't know that for sure. But there is a good chance that that is all that it is to write it in something modern in a good way that can be supported and isn't a high risk. It's often surprising how easy it is to do this stuff well, but it's "just too much" for many companies and so they skimp even on a weekend level project and end up with some real messes.

There is. In one case, you are explaining vendor requirements to the customer. In the other, you are trying to tell the vendor the requirements. Remember with bespoke software, your company IS the vendor.
When I explain Windows patching to a customer, I'm passing on Microsoft's information along with my industry knowledge of how Microsoft behaves historically and some knowledge as to impact to us (how much effort patching takes, time, etc.)
But when the company has bespoke software, it is the company that has to tell this to IT. Technically you could say that we could have the company tell us and then us repeat it right back to them, but that would be awkward. The need for patching the software doesn't come from IT. IT knows that we need to apply patches that get released.
That's very different than overseeing the actual writing of patches. None of the information about how software development works should come from IT, that's not IT's job to know nor anything in the IT skillset. Knowing that software vendors turn out updates and patches for some products (not all) and knowing what patches and updates will be required or desired from bespoke software are radically different things.
So if you are my CEO and you tell me that I'm going to run your bespoke software... it's 100% on you to inform me of what the patch releases are going to be like. I might tell you how much effort I suspect applying those patches will take me, and I might decide when I apply them. But I have no input whatsoever in telling you what to patch, why or when.

That, as well, is not ITs job. Think of IT like a chauffer here. I drive you around, I'm your IT guy. I might clean the car, I might change the oil, but I don't build the car.
Then you go and decide that you are going to design and build a car yourself and tell me to drive it. Nothing you do, no portion of that design, is my responsibility.
As IT, none of those things fall to us. Sure, a company might ask us to step out of IT and do some software oversight because we are "smart people" and that's the best that they have, or maybe we have experience in another arena. But we have to take off our IT hat to it. You might as well be asking the janitor or the receptionist - we all equally have nothing to do with it in our job title, but any of us might be generally smart and well organized or just use common sense.
JasGot was a good person to his company/customer to turn to to get general "where do we start on this" advice. But not because he has some IT knowledge, but because as an IT person he's likely better exposed and has more common sense than other areas of the business because IT has to just handle more things in more areas. He's just a "well read" worker, that he is IT is neither here nor there to the discussion.
That's important to understand in these cases. None of this can be blamed on IT as none of it is an IT function in any way. But IT tends to accept blame for any number of non-IT items and everyone is always thrilled to have a willing scape goat.

But we can say the same about any department. Why didn't operations, accounting, legal, maintenance, janitorial, etc. say something about it? Because 1) it has nothing to do with them even though all of those departments probably depend on it to some degree and 2) because anyone who would think of it would think that it is so obvious that mentioning it to the C-suite would be beyond insulting.

Right, this is something anyone in any management, owner, investor, or just generally an adult, should already know. If you commission something, you are responsible for ensuring the ongoing support.
Imagine deciding to start your own car company but assuming you don't have to worry about parts or support after you make them.
You can't blame IT for not thinking about the basics. It's not ITs job to figure out all the common sense being missed everywhere in a company and jump into other peoples' jobs and tell them what they are doing wrong. That's what AJ would have done, and you know how that works. IT is great to ask questions of when you want some general advice and you just need smart people, but no company wants IT acting like they are in charge of even the CEO and trying to run the company. There's a natural power grab that seems to happen in IT, it's some weird counterpart to the tendency to accept responsibility for absolutely anything and everything.
It's fine for IT to help wherever needed. But we have to keep track of when we are doing IT duties and when we are filling in the gaps of other departments (often a gap in the CEO, CFO, lawyers, etc.) because they are failing and know that IT will do expensive jobs for "free" if you ask nicely.
