The DataAdapter Update method is used to parse changes in the dataset back to the data source. Like the Fill method, the Update method uses an instance of the DataSet and an optional DataTable object or DataTable name as parameters. The dataset
In the case of unit tests for data access, which typically add data records, the data set will typically be:
Then, in the test method, verify that the test method executes correctly by verifying the number of new records or the contents of the

There is a delicate place that must be emphasized. The value of each data in the N-metadata dataset is calculated by the entire Google Book Corpus. In principle, given a 5-metadata set, I can calculate 4-, 3-, and 2-metadata datasets by simply aggregating the correct n-elements. For example, when the 5-meta dataset contains

Of course it's my team! Edward Tufte, Nathan Yau, and Nicholas Felton are data geniuses, while Dan Roam is different. He is good at using simple communication to solve complex problems.

data, using only the outermost words of an n-tuple can also help avoid duplicate computations. In general, we will calculate on 2, 3, 4 and 5 metadata datasets.
MapReduce pseudocode to implement this solution is similar to this:
def map (record):
[Ngram, year, count] = unpack (record)
//ensures that word1 is the first word in the dictionary
(word1, word2) = sorted (ngram[ Ngram[last])
key = (word1, Word2, year)
