De-normalisation. Definition of Parsing. Microsoft Docs. Data flows in packages extract and load data between heterogeneous data stores, which may use a variety of standard and custom data types.
In a data flow, Integration Services sources do the work of extracting data, parsing string data, and converting data to an Integration Services data type. Subsequent transformations may parse data to convert it to a different data type, or create column copies with different data types. Expressions used in components may also cast arguments and operands to different data types. Finally, when the data is loaded into a data store, the destination may parse the data to convert it to a data type that the destination uses. Methods and Challenges of Data Capture. What is already available?
With advancements in modern technology, businesses are now shifting away from manual data entry towards automated data capture, both demographic and behavioural. Fast, accurate and largely inexpensive, automated data capture can save businesses a lot of time and money. Transactions - Difference between transactional and non-transactional.

What is data reduction? - Definition from WhatIs.com. Data reduction is the process of minimizing the amount of data that needs to be stored in a data storage environment.
One group of Web-based companies has built its infrastructure to handle constant growth and global scale from the start. Yahoo, Amazon, Google, Facebook, and other companies like them would be out of business if they had the operational costs of typical datacenters. These hyperscale companies experience IT growth that is orders of magnitude larger than a typical Fortune 500 company. What is hyperscale computing? - Definition from WhatIs.com. Hyperscale computing is a distributed computing environment in which the volume of data and the demand for certain types of workloads can increase exponentially yet still be accommodated quickly in a cost-effective manner.
Hyperscale data centers, which are often built with stripped down commercial off the shelf (COTS) computing equipment, can have millions of virtual servers and accommodate increased computing demands without requiring existing physical space, cooling or electrical power. The savings in hardware can pay for custom software to meet business needs. Outcome 2 Areas of Research.
