If it is a small application dealing with less amount of data, XML files or MS Access could do. Or else, SQL Express should be installed on those computers.

If all the computers are on internet, you can connect to SQL server over internet also. Check that out.

DataSet t = new DataSet();
t.Tables.Add(someTable);

t.WriteXmlSchema("Filename");
t.WriteXml("Filename");


//...
//...

DataSet loaded = new DataSet();
loaded.ReadXmlSchema("Filename");
loaded.ReadXml("Filename");
