  • terminology - What does it mean when data is scalar? - Software . . .
    The term "scalar" comes from linear algebra, where it is used to differentiate a single number from a vector or matrix The meaning in computing is similar It distinguishes a single value like an integer or float from a data structure like an array This distinction is very prominent in Perl, where the $ sigil (which resembles an 's') is used to denote a scalar variable and an @ sigil (which
  • What are the scalar fields and composite fields in JAVA?
    The terms 'scalar type' or 'scalar field' are usually used to contrast them with compound types fields A compound type is easiest to define and it is a type that contains multiple distinct elements These elements can have the same type, in which case the compound is an array or a list, or different types, in which case the compound is typically a struct or a class A scalar type is a type
  • Recommended generic approach to checking scalar field presence in . . .
    There are several questions related to presence field tracking of scalar fields in protobuf 3, but I didn't find any with generic default approach recommendation
  • Why exactly does Java not allow numeric conditionals like if(5 . . .
    0 Well, every scalar type in C, pointer, boolean (since C99), number (floating-point or not) and enumeration (due to direct mapping to numbers) has a "natural" falsey value, so that's good enough for any conditional expression
  • What is meant by a primitive data type?
    It kind of depends on the language For example, in languages like C and C++, you have a number of built-in scalar types - int, float, double, char, etc These are "primitive" in the sense that they cannot be decomposed into simpler components From these basic types you can define new types - pointer types, array types, struct types, union types, etc Then you have a language like old-school
  • Is there a reason replace conditional with table isnt a standard . . .
    for speed you have to use low level arrays, not collections like lists and maps Also, you have to avoid creating objects, unless there is a scalar optimization done by JIT
  • Recommended data structures algorithms for checking peoples . . .
    This answer uses scalar types for simplicity You should consider the range types in Basilev's answer They look to be especially useful for constraints around this kind of problem And if you do go with a single ranged value for the periods, I don't think there's any reason use a fourth table as in the second relationship diagram above
