title: Core Data and Arrays
body: <p>I need to store these values.</p>
  
  <p>x-value = time</p>
  
  <p>y-value1, y-value2, y-value3, ... , y-value10</p>
  
  <p>So for each time, there are these different yValue slices. That is the association between the two.</p>
  
  <p>I am fairly new to Core-Data methodology and I have heard that storing them into arrays are not possible. I do not have to query them, but I do need to store them afterwards in the database after a given session (assume over 1000 of entires -- this is why I don't want to put them all in a NSMutableArray at first).</p>
  
  <p>Is Core-Data the most practical way to attack this problem or is there a better solution to handle such amounts of data.</p>
  
  <p>EDIT:
  So far my model looks like this.</p>
  
  <hr>
  
  <p>Entity 1: Timeslice</p>
  
  <p>Attribute: time - float</p>
  
  <p>Relationship: Values</p>
  
  <hr>
  
  <p>Entity 2: Values</p>
  
  <p>Attribute: yValue1, yValue2, yValue3, ..., yValue10 - float</p>
