Online "Book Flights" facility for an airline

As we begin Part 20, we have:

Rule Taxonomy

  1. Cardinality rules:  data must be present or absent, and/or is restricted in terms of the number of instances.

    1. Mandatory data rules:  one or more data items are required in a particular context.
      1. Mandatory data item rules:  a particular single data item must be present.
      2. Mandatory option selection rules:  one of a set of pre-defined options must be specified.
      3. Mandatory group rules:  at least one of a group of data items must be present.

    2. Prohibited data rules:  a particular data item is not allowed in a particular context.

    3. Singular data rules:  only one instance of a particular data item is allowed in a particular context.

    4. Dependent cardinality rules:  the number of instances of a data item depends on some other data, as in rule statement RS25.

  2. Data content rules:  data is constrained to certain values.

    1. Value set rules:  a data item (or combination of data items) must have a value from a discrete set.

    2. Match rules:  a data item must be the same as or different to some other data item.

    3. Range rules:  a data item must have a value from within a continuous range.

    4. Uniqueness constraints:  a data item (or combination of data items) must be different to other instances of the same data item.

    5. Set constraints:  a set of data items must be the same as some other set of data items.

    6. Data item format rules:  a data item must have a particular format.

  3. Process rules:  occurrences of a process are constrained.

    1. Inter-process interval rules:  an occurrence of a process is constrained as to when it can occur before or after another occurrence of the same process or an occurrence of another process.

    2. Pre-requisite process rules:  a process may only occur if some other process has previously occurred.

    3. Other process pre-conditions:  a process may only occur if some condition (other than the occurrence of a process) has been met.

  4. Structural (definitional) rules:  there are constraints on the structure or definition of a business object of a particular type.

    1. Structural cardinality rules:  there are constraints on the number of components of a particular type in a business object of a particular type, as in rule statements RS117 and RS118.

    2. Data type definition rules:  there are common constraints on the structure or definition of data items of a particular type.

Rule Statements

RS8. Each flight booking request must specify exactly one departure date.
RS9. Each flight booking request for a return journey must specify exactly one return date.
RS11.  A flight booking request for a one-way journey must not specify a return date.
RS12.  Each flight booking request must specify exactly one origin city.
RS13.  Each flight booking request must specify exactly one destination city.
RS14.  Each flight booking request must specify exactly one number of passengers.
RS15.  Each flight booking request must specify at most one frequent flier membership.
RS16.  Each flight booking confirmation must specify at least one passenger name.
RS17.  Each flight booking confirmation must specify exactly one payment arrangement.
RS19.  The departure date specified in each flight booking request must be no earlier than today.
RS20.  The return date (if any) specified in each flight booking request must be no earlier than the departure date specified in that flight booking request.
RS21.  The origin city specified in each flight booking request must be one of the cities served by the airline.
RS22.  The destination city specified in each flight booking request must be one of the cities served by the airline.
RS23.  The destination city specified in each flight booking request must be different to the origin city specified in that flight booking request.
RS24.  The number of passengers specified in each flight booking request must be no less than one.
RS25. The number of passenger names specified in each flight booking confirmation must be equal to the number of passengers specified in the flight booking request that gives rise to that flight booking confirmation.
 

Note that "number of" is styled as part of the term number of passengers in rule statements RS24 and RS25 but also as a keyword (as number of passenger names) in RS25.  While number of passengers is a defined term for a data item that is used in a flight booking request transaction, passenger name also refers to a data item which appears more than once in a flight booking confirmation transaction, but there is no "number of passenger names" data item as such.  In other words "number of" in number of passenger names is a set function referring to the cardinality of a data item rather than a data item itself.

RS26. Each flight booking request must specify whether or not the passengers must travel on the specified dates.
RS27. Each flight booking confirmation must specify whether or not the paying party wishes to include a CO2 offset payment.

• an origin city daytime phone number and
   an origin city evening phone number.
RS35. Each flight booking confirmation for a return journey must specify exactly one of the following:

The combination of placename and postal code included in the postal address (if any) specified in each flight booking confirmation must be one of the combinations of placename and postal code allocated by the postal authority of the country specified in that postal address if the airline can access the postal code information from that postal authority.
