Then, I modified some of the existing Order Details rows by changing their quantities and added several Order Details rows to the DataSet, as shown in the following code snippet: Copy DataSet oDs = new DataSet("NorthwindOrderDetailsData"); oDa.Fill(oDs, "OrderDetails"); //-- Modify the...
The Lambda architecture is a data processing architecture designed to handle massive quantities of data by taking advantage of both batch and stream processing methods. Lambda attempts to balance latency, throughput, and fault tolerance by using batch processing to provide comprehensive and accurate vi...
Projections: Analysts may estimate or predict quantities using algorithms, artificial intelligence, or “manual” analysis. For example, you might predict how many sales you expect to make in the next quarter. The figure you come up with is a projection of quantitative data. Knowing what type of...
Big Datais characterized by the threeVs: variety (seeTable 3), volume, and velocity. Some people will add a fourthV:veracity (seeTable 4). Even traditional data can come in large quantities at great speed. But traditional organizational data is also more predictable, largely because it reflec...
The QBE interface developed for the relational model is closely tied to the forms-based interface. The examples come back in the form of tables, and the user fills in known quantities. The database then attempts to fill in a response table using this information as the restriction information...

The difficulty was compounded by the requirement for item customization—something that our strategic partners did often. Together, this resulted in strategic partners sending us messages that could easily be between 20MB and 50MB of XML. Just the deserialization of those ...
Just the deserialization of those quantities of XML was enough to tie up a Xeon core for up to a minute. We tried offloading the schema validation to hardware XML appliances, but that didn't solve the overall problem—these huge messages were processed orders of magnitude slower than the line...
The last scalar type – that of the physical type – is provided to give context to real-world quantities. The only predefined physical type is that of time; however, numerous libraries are available to define other physical types such as distance, voltage, and current. Users can also define...
where ϑ𝑠ϑs is the solar zenith angle and 𝐋𝐺𝑁𝐷LGND denotes the ground reflected radiance, i.e., the contribution of the solar radiation that after the interaction with the surface is captured by the sensor. The description of the radiometric quantities in Equation (1) is su...
