Is it necessary that the computer at which a c#.net program is to be run should be connected to the developing machine to deploy that program as this program uses oracle database to save user's data items
if yes : then plz explain minimum footprint to install oracle database at each target machine
if no : then how could the target will create and access the oracle database through these 5-7 dll files.
any response will be highly appreciable as I am very uncomfortable being in this confusioin. Thanx all....
I think you're mixing two different things. Application deployment vs. IT Requirements. For your app deployment NO, you don't need to be connected with your clients, use instead something like ClickOnce. Now, for your IT Requirements, well, if your client needs to have Oracle then they need to provide the DB.
Are they willing to pay each for a license? If not, why don't you use a Cloud DB Service? Or something light like Oracle Express (which is, free).

I need your help to answer a question.
I coded a basic c# portable exe application that uses an Access Database on a server computer. On the network there are some client computers that runs this application and retrieve and store data via this database placed on the server computer in a shared folder. Every client coputer can access my database with this connection string:
#"Provider=Microsoft.ACE.OLEDB.12.0;Data Source =\\ANKFILESERVER1\aractakip\DatabaseAd.accdb
So far, there has been no problem. But as known, Access (Oledb) database has a limited capacity to save datas and since i'm worrying that someone change or delete my database files -authenticated for everyone- i decieded to use another database platform like postgresql.
My question is, if i install postgresql on the server computer and migrate my database tables, Are every client computers needed to install postgresql to access my database tables? If yes, what should be my connection string?
Thanks in advance.
You will need a client driver - like psqlODBC - installed on each computer that connects to PostgreSQL via MS Access, yes.
You can install psqlODBC separately, or using the main PostgreSQL installer. The separate psqlODBC-only installer is an msi that can be deployed over Active Directory, making management easier.
The connection options are covered in the psqlODBC documentation.
Microsoft Access is really written for the Microsoft JET / OLEDB engine, and to communicate with Microsoft SQL Server. It works with PostgreSQL, but it doesn't fully "understand" all PostgreSQL's features. It also does some things in totally non-SQL-standard ways that work on MS SQL but do not work on PostgreSQL. So it can be awkward to use MS Access with PostgreSQL due to things like Access not really supporting SEQUENCEs properly. Note, though, that I haven't used Access since Office 2008, so things may have improved.
I have a C#.NET application which connects to a MySQL database in a server.
I have a requirement to do some operations offline.( When the client machine does not have internet and cannot access the MySQL database.) My Plan is to create a MySQL database in local machine. Copy all files required to the local database and perform required operations. When the client machine have the access to the MySQL sever copy back the changed files to the server database.
My question is what are the good Options to use as local MySQL. Is there any lighter version of MySQL available?
I also need to install selected MySQL version with the windows installation package generated for my software.
Thanks in Advance.
When I have these situations I usually fall back to SqlLight. Its a simple embeddable database, and if you are using only the simplest insert /select statements you should not need to maintain much difference between your local database access vs the remote database access.
That said. If you are using something that is not that simple it's usually a good advice to bite the bullet and do the whole mySql install thing on the local machine. Because the maintenance of 2 sets of database access will eat up development time like nothing else.
In your case I would use an embedded database with your offline application, something like FireBird where you don't need to install a 3rd party database etc. The FireBird dll's are linked and part of your application deployment. http://www.firebirdsql.org/
I have finished developing the first release of my application which uses MySQL (locally under one license and hosted under another).
Connecting the application to the hosted database works fine, i edit the connection details within my application to the hosted server details and it works fine.
However, when I try and use it locally (server:localhost etc..) i get an error stating it can not access the server. In my application, i have included the mysql DLL files, but I would prefer the user not to have to install MySQL server which is about a 100MB download (i know its quite small these days but want the install to be as pain free as possible).
I know it would be an easy fix just to add this install as a prerequisite, but i am sure there is a way to do it without this, or maybe not. Is there a script i can run which will run through and setup the server with users etc?
Any help is appreciated.
Thanks

Connecting to a local mysql database implies there's a mysql database service running and was previously installed.
If you want a database you can distribute with your program without having to install a fully fledged database there are quite a few around such as MSSQLCE.
But otherwise, your user is going to have to install mysql on his own machine and keep it running.
Or you could use SQLLite, which is what i have had the best experience with so far.
It should be easy to refactor your Program to use this, and it takes no user setup to use it.
Hope this helps :)
I'm hoping someone can help me. I recently started the development of a windows form application connecting to a remote sql server database. I was happy enough developing it until a potential client queried if they would be able to buy the whole application but they do not want the application connecting to the db via the internet.
I predominantly develop websites using php/mysql but migrated to c# for this particular project. I'm familiar with sql but not sure what database I should be using if the client wishes to have the whole application on their own computer. I've considered providing the database install as a pre-requisite when publishing the app (although I'm currently not sure how to do that) but I'm having reservations whether that is suitable or could lead to more problems. I want to create an application that can install to a single computer and has little to no need for administration. Could someone advise the best way to approach the data storage in this instance.
Because you have already a SqlServer database operating on your remote site, the best path should be to use the LocalDB version of SqlServer Express 2012. See this link about deployment.
If you don't use stored procedures, views and triggers then also the SQL CE could be an option, but you will not have file binary compatibility and you should work on importing your schema and data.
SQL CE is a compact light weight way of going..

i have to develop desktop base software in C#.Net which only produces reports and that reports can be export to any format. that software will be dump into CD/DVD and distributed to all clients and they will install it in their PC (Stand Alon PC). and that will be installer, client can install it himself.
My problem is which database i should choose to build it because this software will be installed by third person. so when one install it database should be install itself, all the data should be in imported into database.
2nd i have to send them month wise data (database exported) which then they will copy/past in specific folder and system itself import it. (that given file (data file) should not be open/read other than my develop software.
is it possible if yes then HOW?
please guide me as i am new comer in VS field but i have programming experience more than 8 years in oracle and 3 months in Java.
This isn't impossible to do.
It sounds like you're wanting users applications to simply interact with a DB that you host. That shouldn't be hard, as there are ADO.net connectors for just about all the popular DBs out there.
I'd suggest simply going with MySQL, ADO.Net connector, and use datasets in your program to read and edit data.
All the client applications would just have to connect to your IP address where you're hosting the central DB and they'd instantly have access to all of that data.
If you're not very experienced in application development, it may be worth it for you or your company to contract a worker to complete this application.
Update
In regards to the update about your client requirements, it sounds like instead you should try connecting to an SQL file that is stored on the client machine. This is EXTREMELY simple to do, and MSVC# has the ADO connector preinstalled. Then, you would have to write another part of the app to perform "updates" every month. You said you need to deliver new data to the customers once a month. Just make the program (when they start it up) check the date, and if required, connect to an FTP site and just download the file to the client machine.
Update II
Ah, ok. That makes things different yet again. This is easier, though. You can make your application read a Database file directly from a CD, which you can mail to people. You should use some sort of PKI style encryption if it needs to be secure. However, due to the nature of the security requirements, I would STRONGLY suggest you contract to someone with experience with encryption, because if you implement something the wrong way, you can expose the data which would be bad :)
I would use an encrypted SQLite file.
