Hi Alexis,

do you mean how to create the installer?
for which OS?

And you want that installer installs both VSERVER + APP ?

for now my app run Windows 7,10
not my application as a server at the same time.

like my app host the server at same time.

i do no now if ADK DB works like that or no.

I'm a little confused how it actually works (ADK DB)

If I understand your question:

The DB ADK is for single connection, standalone applications. For instance, a budget application that manages the expenses of a single user installed on a single computer. Like Apple's now defunct Bento Database app. No network connectivity.

VServer is a standalone database/report server that is accessed in a client/server scenario. Such as the budget app above, yet it connects to a separate VServer via the network that handles many connections at once. Like an office full of people running your budget app connected to the server on a local or remote network where they can all share the data. There is no separate app to manage the VServer - clients just connect to it. You use Valentina's VStudio to do manage the VServer.

Embedded VServer is for when you write your own application that handles the business logic and/or back end code for your budget app server branded under your company name. For example, you write a app that allows you to manage all the aspects of an Embedded VServer externally and all the additional functionality you need. Like VStudio when connected to a VServer - but your app does this instead because you don't distribute VStudio to your clients. "Scott & Company Budget Server" is installed on a client's server. This app uses the Embedded VServer as its database. Your Budget Server app handles all the functions and services of your client budget applications when connected to it via the network.

Basically, it boils down to two things:

1) How will your database be accessed? By one single person on his/her machine only? Use the DB ADK. Or by many people through a network. Use VServer or Embedded VServer.

2) Licensing. If you purchased a VServer license, you can install it on a machine you own for your own use. I have an unlimited VServer license that I use for my office. It is installed on a server I own that I use in my office for all my employees to use for the in-house apps we write and reports we generate. I also have a VDN Developer license (Embedded Server) for the apps we create that use Valentina as a database server branded under my company that we distribute/sell to people royalty free (shameless plug there...).

Hopefully this makes sense. Lynn can probably explain the licensing details a little better than I can.

Embedded VServer is just the same as the regular VServer. The difference is the VDN license you place in your licenses folder. Then you use the signature that you have received from Valentina in the signature text box at login to the server. This keeps others from accessing your DBs. No other user can access your DBs without this signature.

Probably the fastest way to get started with VDN is to install a VServer on your machine. Copy all of the contents of VServer_x64 folder to a development area on your local machine. Put the VDN license in your licenses folder. When you write your app, use the Build Step->Copy Files command and copy in all the files from your VServer folder to a folder in your app bundle. Set the Path variable to point to this folder and when your app starts, have it issue a bash/shell command to start the VServer, connect to it using the signature and you're off and running. You now have an app with its own built in database/reports server courtesy of Valentina.

I was an Oracle wannabe and relied mostly on MSSQL and Crystal Reports. I have abandoned both of these in favor of VDB's suite of products based on cost, ROI, and ease of use. Everyone has their favorites, and everyone has their own story.

I learned through trial and error - feel free to PM me if you need any help. Ruslan and gang are also very helpful if you get stuck.

Let me correct a little
- Emb Signature protects connection to Embedded VServer, but not databases under that server. This is to prevent other ValentinaDB-enabled apps use your Embedded VServer if you want that.
- databases under that VServer can be accessed by somebody if he have access to folder databases, then I can copy dbs and open them by vstudio for example.
- to protect databases - exists encryption in ValentinaDB

Ruslan - yes, that's what I meant to say. Didn't come out as eloquently though. Thanks for the correction.

Alexis - My personal recommendation is to port your existing DB to Valentina, not SQLite. Valentina has far more functionality than SQLite.
