   will be central to your application architecture. You need to develop a series of services that will execute queries

   Most application developers use an IDE, such as link:https://en.wikipedia.org/wiki/IntelliJ_IDEA[Intellij], to help
   with their software development efforts. The IDE provides shortcuts and conveniences that make complex engineering jobs

  You had to apply a bit of brute force, but now you have the rows and columns you wanted, with the data normalized and
  flattened in such a way that each year since "2004" is represented all the way up to 2016.
  
  image:gremlin-asciiart.png[width=225,float=right] Unfortunately, you are unsatisfied. The added Groovy processing of
  "l" feels "wrong" despite it producing the correct output.  It has that unfortunate hack for dealing with the
  possibility that the "endTime" property contains a "null" value, thus hard-coding the "2017" year into the it (you
  want the years through 2016).  You also recall that the Gremlin language has advanced considerably in TinkerPop 3.x
  and that it is usually possible to eliminate closures and other direct processing with Groovy. With those issues in
  mind, you look to enhance your work.

  image:grateful-gremlin.png[float=right,width=110] As you might have noticed from the diagrams of these graphs or from
  the output of the Gremlin Console itself, these toy graphs are small (only a few vertices and edges each). It is nice
  to have a small graph when learning Gremlin, so that you can easily see if you are getting the results you expect. Even
  though these graphs are "small", they are robust enough in structure to try out many different kinds of traversals.
  However, if you find that a larger graph might be helpful, there is another option: The Grateful Dead
