/**
*
* Provides the API for accessing and processing data stored in a
* data source (usually a relational database) using the
* Java programming language.
* This API includes a framework whereby different
* drivers can be installed dynamically to access different data sources.
* Although the JDBC API is mainly geared
* to passing SQL statements to a database, it provides for reading and
* writing data from any data source with a tabular format.
* The reader/writer facility, available through the
* {@code javax.sql.RowSet} group of interfaces, can be customized to
* use and update data from a spread sheet, flat file, or any other tabular
* data source.
*
* <h2>What the JDBC 4.3 API Includes</h2>
* The JDBC 4.3 API includes both
* the {@code java.sql} package, referred to as the JDBC core API,
* and the {@code javax.sql} package, referred to as the JDBC Optional
* Package API. This complete JDBC API
* is included in the Java Standard Edition (Java SE), version 7.
* The {@code javax.sql} package extends the functionality of the JDBC API
* from a client-side API to a server-side API, and it is an essential part
* of the Java Enterprise Edition
* (Java EE) technology.
*
* <h2>Versions</h2>
* The JDBC 4.3 API incorporates all of the previous JDBC API versions:
* <UL>
* <LI> The JDBC 4.2 API</li>
* <LI> The JDBC 4.1 API</li>
* <LI> The JDBC 4.0 API</li>
* <LI> The JDBC 3.0 API</li>
* <LI> The JDBC 2.1 core API</li>
* <LI> The JDBC 2.0 Optional Package API<br>
* (Note that the JDBC 2.1 core API and the JDBC 2.0 Optional Package
* API together are referred to as the JDBC 2.0 API.)</li>
* <LI> The JDBC 1.2 API</li>
* <LI> The JDBC 1.0 API</li>
* </UL>
* <P>
* Classes, interfaces, methods, fields, constructors, and exceptions
* have the following "since" tags that indicate when they were introduced
* into the Java platform. When these "since" tags are used in
* Javadoc comments for the JDBC API,
* they indicate the following:
* <UL>
* <LI>Since 9 -- new in the JDBC 4.3 API and part of the Java SE platform,
* version 9</li>
* <LI>Since 1.8 -- new in the JDBC 4.2 API and part of the Java SE platform,
* version 8</li>
* <LI>Since 1.7 -- new in the JDBC 4.1 API and part of the Java SE platform,
* version 7</li>
* <LI>Since 1.6 -- new in the JDBC 4.0 API and part of the Java SE platform,
* version 6</li>
* <LI>Since 1.4 -- new in the JDBC 3.0 API and part of the J2SE platform,
* version 1.4</li>
* <LI>Since 1.2 -- new in the JDBC 2.0 API and part of the J2SE platform,
* version 1.2</li>
* <LI>Since 1.1 or no "since" tag -- in the original JDBC 1.0 API and part of
* the JDK, version 1.1</li>
* </UL>
* <P>
* <b>NOTE:</b> Many of the new features are optional; consequently, there is
* some variation in drivers and the features they support. Always
* check your driver's documentation to see whether it supports a feature before
* you try to use it.
* <P>
* <b>NOTE:</b> The class {@code SQLPermission} was added in the
* Java 2 SDK, Standard Edition,
* version 1.3 release. This class is used to prevent unauthorized
* access to the logging stream associated with the {@code DriverManager},
* which may contain information such as table names, column data, and so on.

*
*
* <h3>Custom Mapping of UDTs</h3>
* A user-defined type (UDT) defined in SQL can be mapped to a class in the Java
* programming language. An SQL structured type or an SQL {@code DISTINCT}
* type are the UDTs that may be custom mapped. The following three
* steps set up a custom mapping:
* <ol>
* <li>Defining the SQL structured type or {@code DISTINCT} type in SQL
* <li>Defining the class in the Java programming language to which the
* SQL UDT will be mapped. This class must implement the
* {@code SQLData} interface.
* <li>Making an entry in a {@code Connection} object's type map
* that contains two things:
* <ul>
* <li>the fully-qualified SQL name of the UDT
* <li>the {@code Class} object for the class that implements the
* {@code SQLData} interface
* </ul>
* </ol>
* <p>
* When these are in place for a UDT, calling the methods
* {@code ResultSet.getObject} or {@code CallableStatement.getObject}
* on that UDT will automatically retrieve the custom mapping for it. Also, the
* {@code PreparedStatement.setObject} method will automatically map the
* object back to its SQL type to store it in the data source.
