When we use Excel to make table data, we often use its function function to statistic the data in the table. This article takes Excel2003 as an example (in other versions) to introduce you to some of the most frequently used functions in Excel and how to use them. The article begins with an. xls file for everyone to download for reference.
Excel function Series We will also launch a series of examples of Excel commonly used functions, welcome attention.

To better understand the challenges of large datasets with clear cardinality, let's assume that your log file contains 16-character IDs, and you want to count the number of different IDs. For example:
4f67bfc603106cb2
These 16 characters need to be represented in 128 bits. 65,000 IDs will require 1MB of space. We receive 30多亿条 event records every day, each with an ID. These IDs require 384 billion-bit or 45GB of storage. And that's just the space th

If the number of delimiters is greater than the number of variables that contain them, an error occurs. However, if the delimiter is less than the variable, the extra variable contains NULL.Syntax: sscanf (string,format,arg1,arg2,arg++)string--required. Specifies the string to read.format--required.

Enables users to add or remove capabilities as needed
Provides an acceptable, manageable, scalable way to increase and remove capabilities
Allow heavy workloads to balance on many daily-use servers
Provides an allowable degree of internal error
If you want to deploy reporting Services with the Scale-out configuration, note the coll
