Numeric is suitable for storing monetary values and others where exactness is required. However, Numeric is much slower than Real or Double Precision.
There is currently a Money datatype in PostgreSQL, but it has been deprecatedbecause it is US-oriented. They suggest using Numeric instead.
Other Datatypes:
Bit. String of bits.
Bytea. For storing binary strings, i.e., values without a character set or collation sequence attached. Similar to the BINARY LARGE OBJECT or BLOB in SQL 99.
Boolean. Value can be either True or False.
Date. Accepts dates in almost any format and has commands to specify how to handle ambiguous cases. The default and preferred format is the ISO-8601 format, as in 1999-01-08.
There are also datatypes for storing geometric information. And, users may add new types to PostgreSQL using the CREATE TYPE command.
PostgreSQL Precompilers:
As with SQL Server and unlike Oracle, PostgreSQL does not come with a precompiler for COBOL or FORTRAN. However, you may be able to use an SQL compliant precompiler from your compiler supplier, and there is a full-featured implemented of ODBC.
PostgreSQL does provide precompilers/interfaces for C, Perl, PHP, Java, Python and TcL/TK.
SAPdb, Enterprise-Class Open-Source Database
SAPdb is designed for the business enterprise, with 24x7 uptime, scalability and high performance in mind. There are no limitations on database sizes or on the number of users. SAPdb is ACID compliant (fully supports ISO-SQL 92 Standards) and includes all RDBMS and enterprise features expected in an open DBMS such as
Views, triggers, foreign keys, constraints of various kinds, stored procedures, versioning, hot backups, etc. This allows SQL applications written in other databases to be easily portable to SAPdb. SAPdb also includes a C/C++ precompiler and interfaces for Perl, Python, and PHP script languages. For COBOL and Fortran, you will need to consult your compiler source for an SQL pre-compiler. ODBC and JDBC drivers are supported for connectivity to Windows-based and Java-based applications respectively.
SAP also distributes a web-based interface for administering databases and performing SQL duties.
