Right now, in my internship, I'm assigned to create a system that holds employee information such as personal info, education, salary, etc.
All these stuff is kept in a few spreadsheets right now. I need a basic program, but I feel like I should be using MySQL or another database solution to hold the data. I used MySQL before, but it was a PHP/MySQL assignment which I used Wampserver to create the whole system.
Edit: The system will be used by a few computers across the network. When someone makes a change to the system, it will become visible to other computers aswell. (obviously) (Before the edit, I thought that it's gonna be used by a single computer.)
I'm confused right now. Should I create a PHP/MySQL webpage with wampserver (or similar) to hold the information, or not?
Would it be easier or better to combine MySQL with some other programming language (such as Java/C++) and build a GUI? (I doubt it)
Should I come up with a different solution? Without database usage?
Database usage would be the best option. In the end it will come down to what you are more comfortable using, Java/C++ or php, for what you want to do either can work, but remember the database will need to be live at all times and using wamp server wont cut it. You need to learn how to tun a mysql server without wamp, which is easy(Google is awesome). And personally I would have used Java because Java is also easy to link with mysql, just google it a bit, and java doesn't need to run on a server so no wamp needed as you would have needed for php.
EDIT:
Ok if I understand you correctly what you want to do is the following:
1. Identify a pc to be used as a server and assign it a static IP.
2. This must also be the pc that is turned on first every day and turned of last.
3. Create a front end client application that connects to your sql server that you will be running on the server machine.
Now I am assuming this network is rather small, so you wont need a specific computer to just act as server. The server can also be one of the client machines.
The best approach would be to create a mysql server and make sure the firewall is not blocking your sql server. Then create a client application that can access the database over the network using Java, I find this easier than creating a php server for the users because of port forwarding for an apache server is time consuming, I did it once and never again. Java will be easiest to make the application work over the network. Use Netbeans for the development, it's an awesome IDE and it makes life easier when setting up the database connection.
If you have anymore questions please ask in comment, and I will elaborate, since this might be a bit vague lol.
Of course you should use a database for this type of work. That is the best way to organize, search, sort and filter your data without having to reinvent the wheel.
As to the other questions, the choice of language and environment is up to you to decide after evaluating the needs of your application.
Your solution should use a database to store the data and an front-end application to manage the data.
The database and front-end should be seen as two separate layers. In other words create the database using whatever database your are familiar with eg: MySQL and likewise create the front-end using whatever technology youre familiar with eg: PHP.
Personally for this type of requirement i would typically use MySQL / SQLExpress and ASP.Net / MVC3 front-end.
Hope this is helpful.

I'm creating a mobile app for an existing website and trying to connect to a local instance I have running on a MySQL workbench. I've seen others recommend against the use of MySQL but I'm stuck with it, since that's the current database. I'm using expo to run my React Native code. Do I need to use a server, like "MAMP?"
Let me know if there is any more info that is needed.
You cannot connect your app directly to your database.
You will need a server/API that acts as an intermediate between the app and the DB. You can code it in most programming languages and if you know PHP, having MAMP on your system will allow you to build your API with PHP.
I've seen others recommend against the use of mySQL
You should definitely question their reasoning. I've been using MySQL for many years now in small and big projects and it has never been an issue. If they're comparing it to non-relational DBs like Mongo, I can understand, it's easier to setup and maintain a NoSQL database than a relational one.
I assume you're not that experienced but I still purposefully used some terms that may be new to a beginner. Since I don't know your skills, I will refrain from pointing you to specific tutorials/articles.
I recommend you to Google anything you don't understand from this answer.
I am trying to understand the trade-offs between going with MySQL or PostgreSQL on AWS.
Some considerations for me are that I am an amateur database user, so I need to be sure resources are available which allow me to overcome problems quickly. Along these lines, I bought the book 'PostgreSQL on the Cloud' and was all set to go with PostgreSQL since the book laid out a great use case.
One thing held me back though is that it is important for my work to be able to to easily use Excel as a front end for importing and exporting data into and out of the Database on AWS.
It looks like MySQL has an open extension which is fully integrated with Excel and is also well documented. My research into PostgreSQL uncovered a much more uneven integration with Excel and a lot of long painful group frustration a closer integration has not already occurred.
Right now, I am leaning to MySQL, but want to make sure I am not missing something.
Thanks!
Microsoft touts a PostgreSQL plugin as well: https://support.office.com/en-us/article/connect-to-a-postgresql-database-power-query-bf941e52-066f-4911-a41f-2493c39e69e4. Never used it, so can't comment on it.
You mention you are a beginner, so I'll add... be careful about security with either of these options. There are options to encrypt the channel between the client and server, which you indicate is running on AWS. If not secure, anyone would be able to effectively monitor the connections, extract credentials, and do whatever to your AWS-hosted DB. Generally, cloud-hosted DBs should be behind an authentication/authorization login process.
So I'm trying to figure out how to connect to an access database that is on my desktop through html. Everything I've found so far involves the DB being server side and people mentioning ASP.net or just using SQL or mySQL instead. I just need to know how to get the connection up and running. Any help would be appreciated.
You need some kind of web programming language. That can be PHP or ASP.NET or Java or whatever, but you need something else -- HTML can't connect to a database on its own.
I'd highly advise that you take this opportunity to switch to another database server (like SQL Server or MySQL, like you mentioned). Microsoft Access is not well suited to use in web applications.
You're just going to get the same answers here. If you want to stay with Access, ASP.Net is the way to go. Access isn't webbased, most other databases are, so it's a bad fit.
If you want a professional solution, you could get yourself a Sharepoint server and put an Access WebApp on there. But note that this is intended for larger businesses, and priced accordingly, and your database will be limited in features (no VBA for example).
You cannot read or modify files from your (or anyone else) computer with frontend/html/javascript. Yes, you need some backend to connect to your database on your computer/server.
There are databases that work on client side/frontend, like IndexedDB, but it's not ms access and I don't think it's what you want.
I am trying to synchronize 2 different type of database together. Here is a better explanation of what I am trying to do:
I have the MySQL database on a server with the main database. I have an application installed on multiple computers.
I need the main database to be updated with the modification inside the computers and I need the computer version to get the updates from the main database.
I have seen the replication option in MySQL but it's not exactly what I want to do. I have seen other stuff like REPLACE INTO but I still don't see a clear solution.
I'm not asking for a full solution but maybe a good pseudocode or some cool functionality so I can try to implement it. This will be used on my end of school project.
I obviously have a timestamps on each row so I can detect changes.
This is how I would do this if I had an app that will run in different SQL environments.
It will be cleaner if you do the communication between yourApp & DB through some php class. This class instance will be created based on user's SQL version. Then, it is for your code in the class to decide how to connect to your DB.
How could I connect to Embedded MySQL server (libmysqld.dll library) from Delphi XE3? For now I know only one way – use DevArt MyDAC components (specific TMyEmbConnection), but it is paid what is unacceptable for my task now. Try to use dbExpress, but not successful.
So, I have two questions:
1. Can I use dbExpress or any other components from Delphi XE3?
2. Any third-party components (prefer free)?
Thanks
I've used ZeosLib for that in the past.
Worked quite well actually, although really soon it turned out that it was easier to have a central database.
Several people wanted to use the application, and then they wanted to share their changes, and keep things in sync, etc. Luckily, switching to a mysql server was not much more work than copying the data, and changing the connection component parameters.
