===Connection to the driver===
* JDBC Interface
: 1- XA JDBC driver for Postgre (needed for NexJ Express Model)
:: XA Data Source, as for what they mean: XA are for distributed transactions (as per the Open Group specificitions) and non-XA are not (transactions must be single-database). [http://www.theserverside.com/discussions/thread.tss?thread_id=21385]
: @ [http://www.postgresql.org/docs/9.0/interactive/creating-cluster.html PostgreSQL documentation] - [http://www.postgresql.org/docs/9.0/interactive/manage-ag-createdb.html]
* Data Types
: Binary - hex
:: PostgreSQL can not store values of more than several thousands bytes within any data-type except large objects, nor can binary data be easily entered within single quotes. Instead, large objects (BLOB) are used to store very large values and binary data. From PostgreSQL documentation “String Functions and Operators”[6] we catch the function ENCODE(data bytea, type text). This function encodes binary data to an ASCII-only representation. The supported types are: base64, hex, escape.[http://lab.lonerunners.net/blog/binary-data-fetching-through-sqli]
:: ENCODE & DECODE [http://www.postgresql.org/docs/current/static/functions-string.html]:: Example [http://stackoverflow.com/questions/3103242/inserting-text-string-with-hex-into-postgresql-as-a-bytea]
