Hi there and many thanks in advance, Im veeery newby.
I am building a small visual basic 2010 application and I need a better choice for my database (around 20 tables), since now Im using SQL server express 2008 and as far as I understand it is too big and complicated for me (just installing it was a pain for me)
I am looking for an application that will be easy to distribute (maybe just an installer and thats it!) and that can run without problems on old computers with windows xp.
The last thing is that I want to have to chance to install just a client version of my app on a computer and tell it to connect to the database wich will be running on other computer on the same LAN (or maybe on a web server on the future!).
In other words I would like to have the option of selecting "where" is the database to read/write on.
I will thank advices for this implemtation and will respond if somebody needs more details before answering.
Well installing sqlserver in not rocketscience al you need to execute .exe .
Though if you looking for opensource database then have a look at mongodb
MySql is open source and quite easy to use, especially with a tool like PHP MyAdmin:

I am not very familiar with Access database till now i was only programming to SQL Server but now it's time to do so. I am building WinForms application which will be using Access database and i have some question related to that point if you don't mind. My application will be used by multiple users and there will be one access databsae. My questions as below:
Is there any problem with accessing access database in same time by many users or only one user can be connected?
If i develop my program to use access 2016 and some of my users will have diffrent windows version and also diffrent access version
will it works?
Should i know something else? :)
If your client want to have a file based database and this is a project constraint , MS Access is the best choice. If you want a more detailed advice, please let me know how many users will perform Read/Write or Read transactions, the size of the database and if the application will run in client-server mode in a LAN/WAN, Cloud or Remote Desktop environment.
Back to your questions:
Depending on these conditions you may range from 10 to 20/25 users. Remember that you can always try with MS Access and later upgrade to a MS SQL database in a couple of hours.
If your front-end application can link to a 2016 Access database, it will do that without installing MS Access to the clients that will run your App, i.e. the vb.net compiled App will install all needed drivers. If you develop your App within MS Access 2016 (Access Form and reports, some VBA) you can run it with the free runtime version of MS Access, but this only when no older version of Access is installed on the running workstation.
Please check with your client the real reasons for a file-based database...
To answer the questions as asked:
You might run into an issue with this, as access was really designed as a personal use database. Having anything more than a small handful of users hitting against it at once will in fact cause problems, as it's not really well designed for that purpose...
This should in theory be fine, as the application itself is interfacing with the database, not the end user...
It seems like you're taking a step backwards using access for this, and SQL might very well be better suited for this purpose. This isn't me trying to just bash access either, this comes from personal experience. Going with this sort of design is likely to cause you more headaches than good.
I am running Neo4j locally and VB.NET coded software. Right now I have to open the database with Neo4j community in advance of running the software. I'd like to be able to open the database from within the .NET code, like I can with other databases (MS SQL Server, Oracle, DB2, etc.). I cannot find any documentation on how to do this with Neo4j. Of course, I'd also like to check its status and close it from code too.
Appreciate any suggestions. Thanks.

I'm in a database class and the teacher wants us to connect through ssh to an oracle database setup on a school server and it's been extremely frustrating. She wants us to turn in an sql file that will create all the necessary table, insert tuples, run certain select commands which I've found to be very hard to get an sql file with everything after i get everything right and I haven't found a way to test the sql file against the server and I don't think I have permission to drop tables anyway. Anyway my question is there a way I can take an sql file with create table and insert commands to convert it to something like an access .mba database or something local i can mess around with? and help would be greatly appreciated didn't find much help on google.
You seem to be confusing terminology a bit; SQL*Plus is a client application, and the database is a shared server resource. You want to create schema objects from an SQL file, I think. But anyway...
There's a very useful online resource for experimenting with bits of SQL in various flavours, SQL Fiddle. Technically not 'offline' of course, but I'm taking that to mean off your school's network, not necessarily completely isolated. You can create tables and run your inserts in the schema panel, and then run queries against that. Make sure you pick the right database product from the drop-down menu so you're using syntax that is valid for your class. You'll see a lot of answers here with links to demonstration fiddles.
That's great for a lot of things but if you want something a bit more robust and scalable, and entirely offline, you can install VirtualBox and get a pre-built developer VM image which gives you a ready-to-go Linux environment with a database installed and running. You can run whatever you want against that, you have SQL*Plus and SQL Developer available, and you can connect to the DB from your host machine if you want to. You can create and test your scripts against that, and in a format that will be closer to what you have to hand in than you'd use with SQL Fiddle.
This is much less work than installing the Oracle software yourself and learning how to create and manage the database, which I'm guessing is a bit more advanced than you need at the moment, based purely on the kinds of thing your question suggests you're dong at the moment. I think you'd learn a lot from the installation and build process, but I'd get comfortable with Oracle first, and maybe practice in a VM first as it's so much easier to trash it and start again when you mess something up.
If I wanted 'something local I can mess around with', I would go for a VM image. Mo posted a walkthrough of the VM setup as a comment to a previous similar answer, which you might find helpful.
"Something local I can mess around with" in terms of Oracle Database is Oracle Database 11g Express Edition. It's free and can be downloaded from oracle.com. You certainly can test sql-files run through sqlplus on Oracle Database XE.
To get the MS Access (GUI) feeling, download SQL Developer. It's free.
Best of luck!

I recently got a new primary computer. On my old one, I was working with MS Visual Studio 2008 (or maybe an older version - I can't remember now). I had managed to get SQLite working with it and was in the start/middle of building an application.
On the new computer, I now have MS Visual Studio 2010. I have had problems getting SQLite to work with it. Honestly, I haven't tried super hard yet, because I realized I pretty much want to completely redesign this application anyway and it got me thinking... do I really want to use SQLite or some other SQL? MS SQL (or is it called SQL Server)? MySQL?
My end goal is to have an application that can be installed by the user with one .msi file and the user should not have direct access to the database (although at this stage, that is a secondary concern).
It seems like MS SQL / SQL Server is the easiest since it's also an MS product.... Would love some opinions!
(along with the opinions, I'd also love to be pointed to current instructions... I'm a programmer, I'm not a "coding environment setup" person and have always struggled with this. All I want is to get in there and write my application!)
Thanks in advance!

PS... I'm currently working with C# and would prefer to stick with it, but could easily do this in C++ (I'm fluent in all the flavors of C) if that makes a difference with the database.
SQL Server would be a good choice by the sounds of what you're after. Try the express version - it's free, good for development and prototyping and integrates really well with Visual Studio.
The SQL Server Management Studio tool is excellent. I use this to create the databases I need and then use Visual Studio to manage them (saves switching windows and running both applications when you're working in VS all day anyway). I used to have my issues with the old Enterprise manager software but things really seems to have stepped up for SQL Server 2008 and the new management studio.
Like the title of your question suggests, you're wanting to use this with Visual Studio. If you decide to do use SQL Server then you should:
Download the express edition
Download SQL Server management studio
Create a database
In Visual Studio - click View -> Server explorer -> right click Data connections and add connection. Select MS SQL Express and choose localhost as your server. You can then select the database you created using the management studio.
There you have it - integration with VS.
You say you're using C#.Net - well SQL server and .Net go hand-in-hand. Obviously you can hook up to other third party databases but SQL was really made to work with this stuff. It's a powerful database engine and will do everything you'll ever need as well as being well supported by Microsoft and the wider community.
If your final goal is to have hands-off single-click installation then I don't think SQL Server Express is your best bet because it's not a file-based embedded database. It's a great db and very easy to work with, but when it comes to deployment still takes some installation effort. You could try one of: SQL Server Compact Edition, SQLite or Firebird Embedded.
SQLExpress is free and for development purposes is pretty much interchangeable with the full SQLServer
http://www.microsoft.com/express/Database/
SQL SERVER seems to be the logical one.
I've been looking all over the web for a ColdFusion-based SQL administration tool for Microsoft Access and I can't find one that's simple, free and allows running SQL statements. Any suggestions?
Thanks for the recommends, guys, I'll try SQLSurfer. (MSSSME won't work for me.)
"DISCLAIMER: Using MS Access in a (web based) production environment is not recommended."
I understand that, and part of my timeline for this website is to migrate the database to MySQL on our server.
My primary interest in this is to be able to fool around with SQL commands LOCALLY so I can modify some tables. I wouldn't use this in a production environment anyway, especially not one that already has MySQL admin (Don't worry, I have plenty of backups in case I screw something up).
DISCLAIMER: Using MS Access in a (web based) production environment is not recommended.
That said, I have to admit that there are projects, customers, etc. where you can't get around having to deal with MS Access Databases the one or other way.
There is an Open Source project on RIAForge, called SQLSurfer which is a web-based ad-hoc query tool powered by ColdFusion. It is a simple way to execute SQL statements on your database (not restricted to MS Access). http://sqlsurfer.riaforge.org/ Actually there is no download link, but you can still get the code from SVN repo. http://svn.riaforge.org/sqlsurfer/
I have been working with an earlier version for a long time and I find it useful for executing prepared SQL statements. It is a very dangerous tool, especially in production, so I'd strictly recommend to include it in a password protected administration environment and deny public access.
Can RDS satisfy your needs? works with CFEclipse / CFBuilder.
Take a look at SQL Server Management Studio Express - though I've not used it with MS Access, so can't guarantee it'll work.
Hopefully someone more experienced with the two can come along and give more details.
You can easily make one your self.
On Adobe's website you can find at least 5 of those tutorials Here's one http://www.adobe.com/devnet/flex/articles/f4cf_firstapp_part1.html which uses Apache Derby, similar to MS Access.
Of course you need to think some things through, like authentication, making some field for writting SQL statement which is going to be sent as cfquery, but it should be a nice experience to make you'r own "phpMyAdmin" ;)
For MySQL there is CFMyAdmin.com. It might connect or could be adapted to tonnect to MS Access as well. I agree with Henry though, I'd set up the DSN for your access database, the RDS conection in CFBuilder and then use the query tool.
Other alternatives might be Lita (Mac based), or a FireFox add on like Sqlite Manager. They may surprise you as to what they can open.
Also, Charlie Arehart has a long list of CF based SQL Query tools. Maybe one of them could help: http://www.carehart.org/cf411/#query
Good luck
