How to increase the UI font size in SQL Developer Data Modeler 18.2? - oracle-sql-data-modeler

I am using Data Modeler 18.2 and I want to increase the font size of the Interface, but I cannot find a way to do it. I managed to do in the main sqldeveloper, but even though I've searched through many folders and config files, in data modeler I cannot find a way. I'd appreciate it if someone knows the trick!


how to store data on client machine in Electron.js?

I am working on an electron project to keep inventory of a warehouse but I want to store the data on the client-side (on the client's desktop/laptop) and not on a cloud database. How do I do this? Is using an xlsx file a good idea to store the data. As it will come with an added bonus as the user can read the data outside the app if they want to in an excel sheet.
P. S: even if xslx is a way I would like to know other possible ways so I can choose which is more comfortable for me. Thank you.
Edit: sorry I forgot to mention that I might also have to store images in the data.
You have plenty of option. You can store json file and read it when application boot up. As this is node js related thing I would suggest you to use electron store
And xlsx is a good choice but that may be overkill if the thing you are storing is too simple. On windows you can store some settings in registry too. But I prefer the config version.
I have also used sqlite3 database for some app. In Android I believe many app uses sqlite approach to store local database.

sql data base with pictures

I'm working on a SQL server database and I need to have pictures
its for a catalog and most pictures are 1-4 mbs I don't thing embedding the pictures in SQL will be a good idea
what the best solution
till now I used to use access
I would really like to make a wpf form
but when I make a data source I don't understand exactly how linked images work
my main point is that I need it to run really quick and print out a catalog with inventory info each day for thousands of items
I'm looking for a form to manage it
I have tried an access form but access doesn't handle good the linked pictures
Just store the path to the image in the database.
Or, if using SQL 2008 or higher, there is also a new table called FileTable that stores data in the file system directly.
"I need it to run really quick" If speed is a must, Access might not be a good choice for this.. You should use a more professional RDBMS, IMHO.
If this is a hobby project I'd suggest using sqlserver express (I assume you have microsoft knowledge) and either storing a link to an image on the file system/web server or storing the object in the db. For small data volumes either way is likely to perform fairly well.
It is all very easy in MS Access 2010, just bind an image control to a table of paths. For example, my table is called Pictures, with the following entries.
I now just need an image control on a report bound to the table Pictures with a control source set to PicturePath, the images will be displayed.

How to test changes to a cube?

There is a process in our company built by a long-departed dev that pulls data from a cube stored in a MS SQL Analysis Server (which I typically access via Management Studio). The overall process almost never fails and is refreshed several times a day. However, there appear to be some bugs in the calculations that has been handed to me to investigate and fix.
Unfortunately, I knew nothing about cubes when this was handed to me, was not part of the original development process, and generic web tutorials don't seem to quite apply to whatever I'm looking at. On the plus side, trial and error has taught me enough that I can ask a few questions.
The bug is definitely in the calculations. But I obviously don't want to test in Production and I also don't want to make changes without a proper backup (that I know how to revert).
Is there a way to export the whole Analysis db to a .SLN file and open it in VS?
Should I instead use Script Cube as->Create to, change the cube name, and execute to make a copy?
If I'm later asked to add new dimensions or need to edit the data source, what's the best way to do this?
Any other tips?
You can create a Visual Studio project based on an existing cube. This will get everything in a project so you can investigate the calculations, make the necessary changes, deploy to a test environment, and check everything out before deploying to production. Don't forget to check the project into source control ;-)

Best way to store data in wpf app

I just want to know about the best way to store simple data in wfp application. I'm using SQL CE, but sometimes I need to store simple data (for instance one string). I don't want to use for it db, and I think it's the right decision.
Could you please give me a guidance on how should I do that in best way or any useful resource?
Is there any particular features data settings storage for pattern MVVM?
Thank You.
Use Settings for exactly this scenario. It's simple, allows per user and system wide scenarios and is build into Visual Studio nicely.
Double clicking on Settings.settings in the Properties folder of your project (in Solution Explorer) brings up the editor and you can access these in code with something simple like Properties.Settings.Default.StringPropertyX.
if you're going to be upgrading in the future, I suggest that you create a small abstraction layer that you can upgrade to using any DB or other source, when you need to.
Until you do the upgrade, I would suggest a simple XML file using XDocument and XElement (and the rest of that api).
The reason why I am suggesting this is because you can use Linq on them easily and this enables you to change the provider in the future without any problems.
here is the MSDN on XDocument .
I hope this proves to be helpful to you ;-)
p.s. lemme know if this is what you needed or not!
If you publish the application through ClickOnce then you can use IsolatedStorage. It is pretty easy to use, just a few lines of code. You can learn how to use it on WPF isolated storage.
If you don't publish it through ClickOnce then I would suggest you keep it simple and use static class.
you can use file system.. try to create xml file or csv file in the wpf app directory...
you can read and write to same file.. so that you can save what ever you want to that file and read from the same file..

How do I create a database on the computer in flash?

I want to create a a application in actionscipt 3.0 that allows the user to listen to music and read descriptions of the music. For this to happen i suppose there should be a database where the textbits and music is located and then flash fetch the info when the correct buttons are pushed. The database will contain up to 100 tracks and textbits.
The application will function on a stand that won't have a connection to the internet.
What is the easiest way to do this in actionscript 3.0?
If any of you are familiar with UML and thinks this might help in understanding the problem, then here is use-case and flow-chart:

Thanks in advance.
The easiest way to do what you're asking is probably to store the files in a directory on the machine the application is going to be running on, and then design an XML structure for storing your data. The XML is easily loaded in to Flash at runtime and is easily edittable.
Your other option would be running a database server on the machine, creating web services that run locally and push/pull the data from the database, and then call those services from your Flash application.
The first option is most definitely the easiest and should be able to provide exactly what you need. The second would be more geared towards a distributed Flash application where you needed a central data repository for the clients.
If you're building an AIR application, you can use the integrated SQLITE database. But, i agree with Justin, the easiest way is to use a XML file.
You can probably consider using "Local Shared Objects" which is a kind of cookie, with bigger capacity (100Kb by default, but you can change it). Compared to other solutions already proposed, it has then advantage of not requiring any web server.
