So last week the Mole attended the\u00a0SDForum<\/a>\u00a0SAM SIG<\/a>\u00a0meeting to hear\u00a0Ted Neward<\/a>\u00a0speak on “State Management: Shape and Storage:
object\/relational (O\/R) impedance mismatches for persisting
objects between transient & persistent states.” This is a topic that has long fascinated the Mole, which, he discovered, is another way of saying that the Mole was not the target audience. Most of the talk was about the\u00a0problem<\/em>; the Mole was looking for new insights into the\u00a0answer.<\/em><\/p>\n

In the car on the way home, the Mole thought some more about the issues. One of the phrases that had come into his mind during the talk was\u00a0“locality of reference”<\/a>.\u00a0It seems to the Mole that the spectrum of distances from the processor core (registers — cache — RAM — disk — offsite tape) reflects a range of concerns from extremely process-centric to extremely data-centric. An object model is very useful for computing (duh: OO, by definition, couples data with behavior); a relational model is very useful for long-term data storage. One day the Mole will draw a picture and elaborate on this.<\/p>\n

The Mole also recommended\u00a0Fabian Pascal’s writings<\/a>\u00a0(some of which are\u00a0specifically relevant<\/a>) to a couple of people attending the event. The Mole believes\u00a0Santayana<\/a>‘s dictum that “those who do not remember the past are doomed to repeat it.”<\/p>\n","protected":false},"excerpt":{"rendered":"
