ODBC - webopedia
Abbreviation of Open DataBase Connectivity, a standard database access method developed by
Microsoft Corporation. The goal of ODBC is to make it possible to access any data from any
application, regardless of which database management system (DBMS) is handling the data. ODBC
manages this by inserting a middle layer, called a database driver , between an application
and the DBMS. The purpose of this layer is to translate the application's data queries into
commands that the DBMS understands. For this to work, both the application and the DBMS must
be ODBC-compliant -- that is, the application must be capable of issuing ODBC commands and the
DBMS must be capable of responding to them. Since version 2.0, the standard supports SAG SQL.
ODBC - MicroSoft
Open Database Connectivity (ODBC) is a widely accepted application programming interface (API)
for database access. It is based on the Call-Level Interface (CLI) specifications from X/Open
and ISO/IEC for database APIs and uses Structured Query Language (SQL) as its database access
language.

Head
The HEAD Method
The HTTP HEAD method is very similar to the HTTP GET method.
The request looks exactly the same as the GET request
(except the word HEAD is used instead of GET), but the
server only returns the header information.
HEAD is often used to check the following:
The last-modified date of a document on the server for caching purposes
The size of a document before downloading (so the browser can present progress information)
The server type, allowing the client to customize requests for that server
The type of the requested document, so the client can be sure it supports it
Note that HEAD, like GET, is expected to be safe and idempotent
The POST Method
The POST method passes all of its parameter data in an input stream, removing (GET)this limit.
