I'm considering an option to use Oracle Database as web services provider and implement web service logic via PL/SQL stored procedures. I used to code stored procedures some time ago, though I'm not sure what direction should I go in order to use most up to date solutions:
I would like to use amazon cloud for oracle solution. After creating oracle instance, what else should be done in order to use it for serving as web server. I didn't find Amazon Cloud for Oracle Application Server or Glassfish. Also, I need to use JSON but it's unclear does Oracle have such support out of the box. Currently, I found the only option to use Soap 1.1 with Oracle XML DB
Should there be two DB instances for security issues: one node serving as data source and the other one serving as web service provider.
Would appreciate for any ideas and info :)
You might want to review the Oracle Rest Data Services Developer Guide
Amazon provides Oracle access in their product "RDS", but I've never tried it. However, I doubt that you'd be able to use the Oracle web listener directly.
JSON support is not included in Oracle AFAIK, but it should be easy to implement on your own.

Good evening!
I would like to create a web application with Angular 6 but I would like to have Back-end mysql (This is the only basic form I understand a bit) only. Is it possible to have mysql as back-end and without having to use php?
I heard also about mongodb, but can we make requests with conditions for this management system (WHERE, LIKE ... as in sql).
There are two layers in your application - Angular is your front-end presentation layer and an API/Web Service is your back-end data layer which returns JSON data to the front-end. You can use any RDBMS provided your API service supports it. For example, .NET WebAPI supports MySQL through .NET Connector. You can use a variety of API platforms - PHP supports mysql through mysqli and other frameworks.
No, you can not communicate directly between Angular and MySQL. You'll need to build a back-end Web service that calls MySql using php or node. Angular can communicate with this back-end Web service via http.
Here are the steps you need:
1) Learn Angular. Start with the tutorial here: https://angular.io/tutorial
2) Learn how to build a back-end Web service to talk to your mysql backend. You could use php or node.js. See this article for more information. https://www.quora.com/How-do-I-connect-MySQL-to-an-Angular-4-application
3) Learn how to use Angular's http feature to talk to the back-end Web service. (Using the above linked tutorial for help.)
NOTE: You could use firebase instead. It does NOT require that you build a back-end Web service as it provides its own. You can find out more here: https://angularfirebase.com/ or here: https://github.com/angular/angularfire2
If you use Angular in front-end, you can use any backend with it to connect to MySQL database, for example:
Jersey web service written in Java
Php with mysqli
You can also use noSQL database with MongoDB or firebase.
The choice depends on the structure of your database (so you decide if it is better to have relational on noSQL database) and another very important thing is the hosting plan on which you want to deploy your website. If you have a shared server on which you have mySQL and you want to create a relational database, I recommend you to use the following architecture (Angular as front-end, php mysqli as back-end only to select/update from database, and mySQL to store database).
I need to write a web application, which works only with MySQL database, but all actual data lies within an Oracle. So now i'm looking for some way to syncronize partially or use some automated tools to do that. Or just for a best practice for that case. To be clear, there's no way to use Oracle directly from web applications due to security policies. Any advices?
You can use tungsten replicator http://code.google.com/p/tungsten-replicator/ or also there is option of Data Integration / ETL tools like talend https://www.talend.com/resource/etl.html.
Back in the MSSQL 2000 timeline, there was an IIS integration layer that allowed HTTP GET commands to make select statements, and there were other SqlXml niceties that worked (not that fast or well but they worked) out of the box. I gave a chance to expose database stuff fairly quickly.
What is the comparable technology for MSSQL 2008/2012? I saw slashDb (http://www.slashdb.com/) and it seems to do that, but I am trying to understand the other options out there. Just SQL Server crud and sproc access.
Thanks.
Yes, SlashDB does exactly that and more. Full disclosure: I am the founder and CEO.
Once SlashDB is installed you would use its web interface to connect it with your database. Depending which database login and database schema you use for that connection, you will have the tables and views from that schema turned into of URL endpoints.
Those URLs can be followed in the browser but they are also API endpoints in JSON, XML or CSV. It works for reading and writing (you can control that in user configuration).
In addition to that you can define a set of parameterized SQL queries. Each query is given a name and instantly becomes an API endpoint too.
In order to help you getting started easily SlashDB is available on AWS and Azure marketplaces, as a Docker container from DockerHub, pre-built virtual machines or as .rpm and .deb packages for installation directly on Linux.

The nearest equivalent may be SOAP/HTTP endpoints, however Microsoft has deprecated them for various reasons and recommends WCF or ASP.NET instead. Although the simplest way to get a quick CRUD setup is probably to use a framework or ORM that generates it for you, like LINQ to SQL or whatever else suits your needs.
I am an experienced web programmer that has sadly had little experience with Web Services and technologies like Silverlight - I've done a lot of PHP, Javascript, CSS and MySQL. I recently have been assigned to learn Silverlight and connect a new app to a MySQL database. After a full week of trying to get this working, I'm really hoping someone can answer these questions:
I have found the MySQL .NET Connector - am I correct that this is not compatible with Silverlight and I do not need it?
I understand I must use a Web Service for this. Can I use WCF or WCF RIA, or am I best using a more traditional web service method like REST or SOAP?
What's the best web service method for many quick queries (such as updating a search as the user types in the keywords)
Do I have to use technology like LINQ, Entity SQL, ADO.NET Framework, or a stored procedure? Is one of these the best way to do it or should I just skip them all and create a simple web service?
What's the best source to learn how to do specifically Silverlight VB.NET and MySQL and learn to do it the best way as explained above. Everything I've found (books and websites) seems to be in C#, not a Silverlight product, or just uses built in SQL Server support. Very frustrating!
For our web app, we need to be able to give the buyer not just access to our client side application via a browser but also the server side so they can OPTIONALLY host the entire product themselves. We're hoping to have one installer for them on their server (so they wouldn't have to set up php or mysql to host the product for example). If I use a VB.NET website and web service, will that deploy as just an exe or dll so the user won't have to install anything special? Is installing mysql on their servers unavoidable? Please advise.
Thank you!
Wow, lots of questions in a single question.
You can't use this from Silverlight.
WCF and WCF RIA are both technologies while SOAP and REST are protocols that are both supported by WCF. So yes.
Quick queries require good code and a well tuned database, the protocol won't be an issue.
LINQ, Entity SQL, and ADO.Net are all database access technologies and have nothing to do with web services. You'll need to build a web service and then connect it to a database using some database access technology. Which one you use depends on what backend you have.
C# is much more common. Most of the MSDN content has VB.Net as well. MySQL isn't an MS technology. You can use MySQL with Entity Framework and then expose that using WCF RIA Services.
If you use VB.Net as the server side technology they will need to be running Windows with IIS and have .NET installed. They will also have to install MySQL if they want to host it.
Can MySql database be used as a back-end of a desktop application. What are the various possible ways to do it?
I would say that it would be possible, with each desktop application client connecting to a centralized mysql database, at the client site, or possibly connecting to a centralized server managed by you/your company, and like #Neil Butterworth mentioned there are various APIs/methods to use to talk to the database. However, if you are looking to embed a database with your application, I would suggest looking at sqlite instead. It is a small,lightweight relational database designed for being embedded into applications.
To add to nstehr's answer, see:
SQLite vs MySQL
How scalable is Sqlite
How do databases work internally
Yes, I have done so on more than one occasion. Build your database in MySQL, either locally or on a remote machine, and then set up your connection to the database using the appropriate API.
There is a package for connecting to a .NET application (just search .NET MySQL library and it should turn up), with Java you can use Hibernate (or any other ORM Framework) and set the dialect to whichever version of MySQL you're using in the hibernate.config file. Or you could just use ODBC/JDBC directly. I'm sure other languages have their own support.
Any application, if built well, should be able to be supported by a variety of databases, and it should not affect the application. Switching between databases should involve changing a couple of property files at most, and then testing for database-specific idiosyncrasies.
Can MySql database be used as a
back-end of a desktop application
Yes, of course - just like any other database.
What are the various possible ways to
do it?
What do you mean? Do you mean how to access the database from the app? Lots of ways - some are:
via its native C API
via ODBC
via JDBC
Which one you use will of course depend greatly on which language(s) your desktop app is written in.
