<p>This International Standard, Remote Database Access for SQL (RDA), defines a model for the remote</p>
<p>interaction of an SQL-client and one or more SQL-servers through communication media, and defines</p>
<p>the encoding of messages, the semantics of messages and associated facilities for mediating the</p>
<p>interaction between one SQL-client and one SQL-server.</p>
<p>This International Standard also defines a mapping of the RDA Protocol to the specific communication</p>
<p>inhastructures TCPIIP and Transport Layer Security (TLS).</p>
<p>This International Standard relies upon the facilities provided by ISOIIEC 9075 (SQL) and</p>
<p>ISOIIEC 9075-3 (SQLICLI).</p>
<p>This International Standard also:</p>
<p>- identifies potential security vulnerabilities in remote database access using RDA,</p>
<p>- defines RDA facilities which protect against the potential vulnerabilities.</p>
<p>Normative annexes provide:</p>
<p>- a Conformance Proforma,</p>
<p>- an optional language independent Application Programming Interface defined in the notational</p>
<p>conventions of ISOIIEC 9075-3 (SQLICLI) for invoking RDA Operations,</p>
<p>- an optional mapping of ISOIIEC 9075-3 (SQLICLI) functions to RDA Operations,</p>
<p>- definitions of optional SQL-servers, the RDA Location Server and the RDA Support Server, to</p>
<p>facilitate interoperation and data distribution in a heterogeneous environment,</p>
<p>- a set of security profiles that identify which RDA facilities and other security facilities are required</p>
<p>for different levels of protection against potential vulnerabilities.</p>
<p>Informative annexes provide:</p>
<p>- an analysis of security service requirements,</p>
<p>- an ASN. 1 specification for the RDA Protocol,</p>
<p>- an ASN. 1 specification for the encoding of multiple rows.</p>
<p>This International Standard does not constrain:</p>
<p>- conforming RDA-client environments to be implemented using any particular processor</p>
<p>decomposition,</p>
<p>- conforming RDA-server environments to be implemented using any particular processor</p>
<p>decomposition.</p>
<p>This International Standard refers to but does not define:</p>
