CBMS ERP Sparse Fields
1Implementation of sparse fields.
The purpose of this module is to implement "sparse" fields, i.e., fields
that are mostly null. This implementation circumvents the PostgreSQL
limitation on the number of columns in a table. The values of all sparse
fields are stored in a "serialized" field in the form of a JSON mapping.
