Therefore we have arbitrarily selected a small number of data types (xsd:string, double, integer, date, boolean).
For each attribute we define its type, that can be string, integer, date, real or file.
Data types used are: categorical values, text, integer, date, and real.
Similarly, datatype specification also applies to all PSSAs, e.g. strings, integers, dates, URLs, or some unique provider-specific service data formats (see Fig. 2).
In the case of relational databases, accesses are normally done over simple data types (e.g., strings, integers, dates); however, when NoSQL databases are used, storing and accessing full documents is a quite typical case.
Each property may be a simple type (strings, integers, dates) or complex types (contacts).
The possible data types are integer, decimal, date, text and pre-defined value sets.
These include requiring fields and adherence to a particular data type; e.g., integer only, dates and times with one of a number of specified formats, such as dd/mm/yyyy or mm:ss, and minimum and/or maximum accepted values for numeric fields allowing the definition of ranges.
To facilitate comparisons between studies that reported relapse times by integer weeks, relapse dates reported as exact days were analyzed as the next full week from infection.
· scalar is used to hold scalar data, which is a single value of type integer, real, boolean, string, date, etc. · array is used to hold a one dimensional array data structure of primitive data type such as integer, real or boolean but it is not suitable for all data types such as string and date, for example.
The basic data types for content tables include integer, numeric (real number), date and text.
