Is there a way to communicate these Platforms effieciently?
I'm saying, something like exporting (SQL Server)and load (Matlab) but in an efficient way?
I've found adodb_tools on File Exchange to work the best so far. It's much faster than the database toolbox or any prior wrapping solutions.
Doesn't require additional toolboxes but in all likelihood will require you're on Windows for the ADO OLEDB ActiveX support.
Use MATLAB's capability to run Java code in order to access any database that provides a JDBC driver. If you mind using Java, buy the Database Toolbox as mentioned by #b3.
As mentioned use Java and the JDBC driver for your chosen database.
If you look through Stackoverflow there are a few posting about connecting MATLAB and MySQL.
MySQL and Matlab
and
How can i remotely connect ODBC using Java in Windows XP?
These solutions should work with a little tweaking for your database driver.

I am trying to connect to AWS Athena via my Windows as well as Mac system. My goal is to have a SQL Editor that I can use to perform quick research about the data. I was trying to find tools and tutorials for connecting to Athena. So far I have only found some tutorials around SQL Workbench. What are some other tools that you guys leverage and is there something particular that you like about that tool and how easy was it to setup either on Windows/Mac.
I use SQuirreL SQL for connecting to Athena. It has served the purpose so far. Once you import the JDBC drivers(you can download them from AWS's site) the tool itself is pretty straight forward to setup. The URL that you can use to connect can be seen here -
jdbc:awsathena://AwsRegion=<AWS Region>;User=<AWS Access Key>;Password=<AWS Secret Key>;S3OutputLocation=<S3 folder>
I'm pasting the "Overview" of SQuirreL below:
SQuirreL SQL Client is a graphical Java program that will allow you to
view the structure of a JDBC compliant database, browse the data in
tables, issue SQL commands etc, see Introduction. The minimum version
of Java supported is 1.6.x as of SQuirreL version 3.0. See the Old
Versions page for versions of SQuirreL that will work with older
versions of Java.
SQuirreL's functionality can be extended through the use of plugins.
A short introduction can be found here. To see the change history
(including changes not yet released) click here.
For a more detailed introduction see the English or German of our
paper on SQuirreL.
Susan Cline graciously took the time to document the steps she
followed to setup an Apache Derby database from scratch and use the
SQuirreL SQL Client to explore it.
Quite some time ago Kulvir Singh Bhogal wrote a great tutorial on
SQuirreL and published it at the IBM developerWorks site. He has
kindly allowed us to mirror it locally. The tutorial is not really up
to date but especially for doing the first steps it is still of help.
SQuirrel was originally released under the GNU General Public License.
Since version 1.1beta2 it has been released under the GNU Lesser
General Public License.
Another tool that I have used pretty extensively is SQL Workbench. This is also sort of recommended on the AWS site. The is good, but I found that it would hang up sometimes and I would loose my work.
Both of these can be easily downloaded from the links provided or if you like to use CLI then Homebrew can be used on MacBook or Chocolatey on windows
Some other tools that you can use are DataGrip by JetBrains. Guide to setup the tool can be seen here. The functionality of DataGrip is also built into IntelliJ Ultimate Edition.
DB Visualizer is another tool that can be used to connect to AWS Athena the guide to connect can be found here
TeamSQL and Razor SQL are some other tools that you can leverage.
One of the strengths of JDBC drivers is that as long as a tool supports JDBC, you can use it for any data source which has a JDBC driver. First, get the JAR file for the JDBC driver for Athena here: Amazon Athena Connect with JDBC. Java works across platforms, so as long as you have Java in your Windows/Mac environment, you should have no problem using any of these tools.
The tool SQL Workbench/J is fairly popular, but I find it frustrating to work with when switching between multiple databases.
Another tool is Squirrel SQL, which also supports JDBC drivers. I prefer it, but it looks a little less pretty than SQL Workbench/J. Once you've downloaded the JDBC driver, configure it in SquirrelSQL by going to Drivers and then adding a new one. Label it "Amazon Athena" and specify the Example URL as jdbc:awsathena://AwsRegion=[Region];User=
[AccessKey];Password=[SecretKey];S3OutputLocation=[Output];
[Property1]=[Value1];[Property2]=[Value2];...
Leave the Website URL Blank, but specify the Class Name as com.simba.athena.jdbc.Driver. Add the .jar file of the JDBC driver to the "Extra Class Path" page.
Once you've set up the driver, you can set up connections by going to the Alias tab and hitting the plus sign. Simply fill in the values in the example URL to point to your data source. Once you're connected, you're good to start writing queries.
SquirrelSQL saves the connection information for you, allowing you to quickly jump between data sources, and makes it easy to write multiple queries in one input window, with their outputs going to separate tabs in the output pane. I've used it for database, exploration, DDL, and regular day-to-day tasks with data. It's been good for most anything I've connected it to. It is definitely not perfect, but it's getting better all the time.
I guess you need a Docker SQL Editor that you can use to perform quick research about the data.
But I suggest two ways.
One is Offline/Online and with installation methods, which you can use with a fixed connection.
The first solution is to select a system as a server and connect to it from other operating systems. This is the traditional / old solution.
In the second solution you just need to be trained to work with Docker. This is a newer and more popular solution.
if you want use MySQL in MAC read this article :

If you want use MySQL in windows read this article :

But you need a synchronous space for use MySQL or other DBMS you can use docker.
Docker is very Flexible . But you need connect to internet.
If you want use Docker read this article and view docker site :

Having to support an older VB.Net application, I get performance issues when several workstations are working with the MySQL database via ODBC at the same time. I'm now thinking about switching from ODBC to the MySQL Connector/NET.
I don't know Connector/NET at all. Does anybody have experiences with a switch like this? Are there any caveats? Is it even worthwile? Would it be a lot of work (the app relies heavily on MySQL)? I didn't find anything about the efford needed. Any thoughts? Thanks.
Can anybody help me in connecting my MySQL database from my 4D database application. I have tried but still could not find any help. Please note that i want it without ODBC and want to directly connect to my MYSQL db.
I have integrated MySQL with 4D without ODBC using this C compiled library
https://www.pluggers.nl/product-category/4d-plugins/
The price is WORTH EVERY PENNY. I used both their MySQL and PostgreSQL wrappers.
I talked to the developers, they have done just what you want. Provided a 4D component C library wrapper to target functionality of other databases.
It is VERY FAST.
If you decide to use the ODBC connector use this command to target a pre established ODBC connection on the machine.
http://doc.4d.com/4Dv15/4D/15/SQL-LOGIN.301-2007437.en.html
Also. ignore the connectivity API is for version 2004 and is not relevant to your question.
-James
What I read is that 4D doesn't do this without the API (additional price of $59), API details seen here.
Another option I found, be out date, is to write something yourself in the C compiler which can talk to MySQL directly.
You may connect via web service such as SOAPand REST.
You may also retrieve both data in and out via JASON.
Also, Since 4D now support PHP, you may build an APPLICATION in php that will do the migration or Synchronization.
But if you are looking for Direct Query, I don't know about the latest version of 4D, but as for 4Dv12 that would be bloody if you tried to build your own, since the simplest way is to do it is via ODBC.
Before, I tried to connect it via EXTERNAL PROCESS and SERIAL COM using .Net but it's just to risky, so i just Give up.
Is there any way to use MySQL without install? I am making an desktop application using Visual Studio and C# that uses MySQL. I will use this program on another computer.if this computer has no MySQL installation my program will also work? Can I move my database with my application?
No, you do not need the server installed locally. You do need some sort of client, though. For C, you would need the mysqlclient library. I assume C# has something similar to enable the CLR to talk to MySQL.
If you are looking for a portable database, check out SQLite. As for the best library for C#, see these answers:
What is the best way to connect and use a sqlite database from C#
Is there a .NET/C# wrapper for SQLite?
No... You will need the computer to have mysql and your compiled code. What you CUD do if your database is not too big is hardcode the data storage and retrieval in your code itself.. in that case you wont need mysql installed there..
OR you cud allow network access to mysql on another machine(server) in that case u only need mysql on the server
What is the best component to use when connecting to a Mysql 5.1.x in Delphi and why ?
No other DB components could beat DevArt DB Components, they have MyDac and UniDac, both of them could use direct access to the database without requiring mysql client to be installed on the client machine, beside they offer fast performance and high quality compared to other components
Data Access Components for MySQL
Universal Data Access Components
and check the pages above to know why ;-)
You should take a look at AnyDAC, supports MySQL and a lot of other databases.
Devart and microOLAP both offer components to access MySQL databases. Devart also have dbExpress drivers for dbExpress users.
Bob Swart has published Delphi for Win32 VCL Database Development on Lulu, if you need any help.
Don't forget that MySQL's client dll are GPL-ed, and if you are using it to connect to server, your app must be GPL-ed.
There are alternatives. Components that connect directly to MySQL skipping GPLed dlls. DevArt has such components (direct and dbx), and there are free components that can connect directily on tory.net.
I don't use MySQL, but when I can, I prefer dbExpress. It's unidirectional, which makes it pretty fast. Though I haven't done any benchmarking recently.
If dbExpress isn't your thing, I found this list of components for MySQL access.
