Advantages of PL/SQL
PL/SQL has the following advantages:
• SQL is the standard database language and PL/SQL is strongly integrated with SQL. PL/SQL supports both static and dynamic SQL. Static SQL supports DML operations and transaction control from PL/SQL block. Dynamic SQL is SQL allows embedding DDL statements in PL/SQL blocks.
• PL/SQL allows sending an entire block of statements to the database at one time. This reduces network traffic and provides high performance for the applications.
• PL/SQL gives high productivity to programmers as it can query, transform, and update data in a database.
• PL/SQL saves time on design and debugging by strong features, such as exception handling, encapsulation, data hiding, and object-oriented data types.
• Applications written in PL/SQL are fully portable.
• PL/SQL provides high security level.
• PL/SQL provides access to predefined SQL packages.
• PL/SQL provides support for Object-Oriented Programming.

The SQLException class provides information on a database access error.
Each SQLException provides several kinds of information:
• a string describing the error. This is used as the Java Exception message, and is available via the getMesage() method
• A "SQLstate" string which follows the XOPEN SQLstate conventions. The values of the SQLState string as described in the XOPEN SQL spec.
• An integer error code that is vendor specific. Normally this will be the actual error code returned by the underlying database.
• A chain to a next Exception. This can be used to provided additional error information.
QUARTZ

    Hadoop [8] is an open source implementation of MapReduce programming model which runs in a distributed environment. Hadoop consists of two core components namely Hadoop Distributed File System (HDFS) and the MapReduce programming with the job management framework. HDFS and MapReduce both follow the master-slave architecture. A Hadoop program (client) submits a job to the MapReduce framework through the jobtracker which is running on the master node. The jobtracker assigns the tasks to the tasktrackers running on many slave nodes or on a cluster of machines.

Hash maps allow the execution time of basic operations, such as get() to remain constant even for large sets. HashSets and HashMaps are implemented using a data structure known as a hashtable. ‘The concept of a hash table is a generalized idea of an array where key does not have to be an integer.

    The interpreter is specially designed to take the script that needs to be run and translates it into machine code that will work with the servers CPU layout. This is better than compiled code for web applications as compiled code is written for a certain type of machine architecture, hence if the server hosting a website changed then the architecture could change. This would mean that the application would no longer work as the compiled code is incompatible with the new machines
