object MakeSchema

The MakeSchema object attempts to infers the domain of a relation without a domain specification and creates a new relation with the inferred domains by examining the data. Should be checked and overridden when inaccurate.

  4. def analyzeType(c: VectorS, samplePercent: Int = 100, mapString: Boolean = false): (Vec, String)

    Analyze the type of a given VectorS by using regular expression matching.

    Analyze the type of a given VectorS by using regular expression matching. Types can be Integer (I), Long (L), Double (D), etc.

    c

    the VectorS to have its type analyzed

    samplePercent

    the percentage of 'c' used to analyze the type of 'c'

    mapString

    flag used to map each distinct string in 'c' to a distinct integer

  5. def apply(r: Relation): Relation

    Infer the domains of a domain-less relation and create a new relation with the inferred domains (e.g., 'IIDIS').

    Infer the domains of a domain-less relation and create a new relation with the inferred domains (e.g., 'IIDIS').
