> 2.2.2 Datatype
> 2.2.2.1 Each column employs one of the following datatypes:
> a) Identifier means that the column shall be able to hold any key value generated for that column.
> b) Integer means that the column shall be able to exactly represent integer values (i.e., values in increments of
> 1) in the range of at least ( − 2n − 1) to (2n − 1 − 1), where n is 64.
> c) Decimal(d, f) means that the column shall be able to represent decimal values up to and including d digits,
> of which f shall occur to the right of the decimal place; the values can be either represented exactly or
> interpreted to be in this range.
> d) Char(N) means that the column shall be able to hold any string of characters of a fixed length of N.
> Comment: If the string that a column of datatype char(N) holds is shorter than N characters, then trailing
> spaces shall be stored in the database or the database shall automatically pad with spaces upon retrieval such
> that a CHAR_LENGTH() function will return N.
> e) Varchar(N) means that the column shall be able to hold any string of characters of a variable length with a
> maximum length of N. Columns defined as "varchar(N)" may optionally be implemented as "char(N)".
> f) Date means that the column shall be able to express any calendar day between January 1, 1900 and
> December 31, 2199.
> 2.2.2.2 The datatypes do not correspond to any specific SQL-standard datatype. The definitions are provided to
> highlight the properties that are required for a particular column. The benchmark implementer may employ any internal representation or SQL datatype that meets those requirements.

> one thing might be clear that we should replace bigint type which is now used in web_returns and store_returns with int type.
> another thing that might need to be further discussed is - shall we use bigint to meet 2.2.2.1 b)?
