This is the size used for start+increment and random AutoNumbers. For replication ID AutoNumbers, the FieldSize property of the field is changed from long integer to Replication ID. [2] If an AutoNumber is a long integer, the NewValues property determines whether it is of the start+increment or random form. The values that this property can ...
A common practice is to entitle list articles as List of ___ (for example List of Xs).If (as is often the case), the list has multiple columns and so is in layout table form, the name or title List of Xs is still preferable to Table of Xs or Comparison of Xs (though the latter may be appropriate for articles that are actual tables of data comparing numerous features, e.g. Comparison of Linux ...
PIIs include direct identifiers (name, social security number) and indirect identifiers (race, ethnicity, age). [2] Identifiers can be sensitive and non-sensitive, depending on whether it is a direct identifier that is uniquely associated with a person or a quasi-identifier that is not unique. A quasi-identifier cannot pin down an individual ...
