I searched this forum for 'time series' and found three unanswered about
how to create a time series for timestamped data as described in
http://orientdb.com/docs/last/orientdb.wiki/Time-series-use-case.html
I daresay this is a common scenario and many are using it, however it is a
difficult concept for newbies to grasp!
Via the java API I have created five classes, to capture years to hours and
point to my log entry record...
//log entry
OrientVertexType logentry= graph.getVertexType("logentry");
if (logentry== null)
{
logentry= graph.createVertexType("logentry");
//bunch of other properties
}
//hour link logentry
OrientVertexType hour = graph.getVertexType("hour");
if (hour == null)
{
hour = graph.createVertexType("hour");
hour.createProperty("coraxhits", OType.LINKMAP, logentry);
}
//day link hour
OrientVertexType day = graph.getVertexType("day");
if (day == null)
{
day = graph.createVertexType("day");
day.createProperty("hour", OType.LINKMAP, hour);
}
//month link day
OrientVertexType month = graph.getVertexType("month");
if (month == null)
{
month = graph.createVertexType("month");
month.createProperty("day", OType.LINKMAP, day);
}
//year link month
OrientVertexType year = graph.getVertexType("year");
if (year == null)
{
year = graph.createVertexType("year");
year.createProperty("month", OType.LINKMAP, month);
}
Next I have written simple loops to generate instances of the year, month,
day and hour verticies (12 x month 31 x days etc...)
But now how do I enter a logentry?
