Why do we need to preprocess data?

-


By preprocessing data, we

  • Make our database more accurate: We eliminate the incorrect or missing values that are there as a result of the human factor or bugs.
  • Boost consistency: When there are inconsistencies in data or duplicates, it affects the accuracy of the results.
  • Make the database more complete: We can fill in the attributes that are missing if needed.
  • Smooth the data: This way we make it easier to use and interpret.

 T he fundamental steps involved in the process of connecting to a database and executing a query consist of the following: Import JDBC packages. Load and register the JDBC driver. Open a connection to the database. Create a statement object to perform a query. Execute the statement object and return a query resultset. Process the resultset. Close the resultset and statement objects. Close the connection. These steps are described in detail in the sections that follow. 1.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...

Pure Versus Partial EC

Pure Versus Partial EC EC takes several forms depending on the degree of digitization (the transformation from physical to digital). Companies utilizing pure EC conduct all of their business online. Businesses utilizing partial EC conduct a portion of their business online and a portion of their business off-line OR,    Pure E-electronic commerce refers to a situation where a business transacts its business activities PURELY online. that is, the goods or services sold do not have any physical presence. take a business that sells software, for example, you just pay and download, or one that sells music files online. Partial E-Commerce on the other hand refers to a slightly opposite situation where a business has an online presence, but still has a physical location for the goods and services it sells. For example, Amazon, Walmart, and any other you can think of. you buy the goods online but receive them physically.                   ...
