The Java DOM Parser allows programs to access and update the structure and contents of XML documents. It represents an XML document as a tree of Node objects. When parsing an XML file with a DOM parser, it returns a Document object representing the entire file as a tree structure. This tree can then be traversed and manipulated using common DOM interfaces and methods to extract information from the XML document.
This document provides an overview of input and output (I/O) in Java, including reading and writing local files. It discusses Java streams for reading input and writing output, and the classes for character-based and byte-based streams. The document outlines connecting to files, reading and writing characters and objects to files, and file management tasks like creating directories and deleting files.
Hibernate is a popular Java ORM tool that allows mapping of Java objects to database tables. It handles common persistence tasks like caching, lazy loading, and dirty checking automatically. Hibernate objects are simple POJOs that follow some conventions for mapping. The SessionFactory manages object-relational mappings and connections to the database, while Sessions represent a single-threaded conversation between the application and database.
The document discusses files, streams, and different classes in Java for reading and writing files and streams. It explains that files exist on a local file system while streams represent a flow of characters. It also discusses the process of opening, reading from, and closing files, as well as using classes like FileReader, FileWriter, FileInputStream and FileOutputStream for reading/writing characters and bytes. It recommends using BufferedReader and BufferedWriter for more efficient reading of lines and writing of strings.
The Java I/O package supports Java's basic input/output system for accessing external data from sources like files and networks. It defines streams as logical entities that produce or consume information, with byte streams for binary data and character streams for Unicode text. Streams are linked to physical devices and behave consistently across different types of devices. The package defines hierarchies of input and output stream classes, with abstract base classes like InputStream/OutputStream for bytes and Reader/Writer for characters.

This presentation provides an overview of object-oriented programming (OOP). It discusses key OOP concepts including objects, classes, encapsulation, inheritance, polymorphism, and message passing. Objects are instances of classes that contain both data and behaviors. Classes define common properties and methods for objects. Encapsulation binds data and functions together, while inheritance allows classes to inherit properties from parent classes. Polymorphism allows the same message to be interpreted differently. Message passing facilitates communication between objects.
2 lesson 2 object oriented programming in c++Jeff TUYISHIME
Object oriented programming provides a way to create modular programs using objects. An object contains both data and functions that operate on that data. Classes are used to create objects, with classes binding data and functions together. Classes allow data to be hidden from external access via encapsulation. Objects of a class can inherit properties from other classes through inheritance. Polymorphism allows objects to take on multiple forms.
NHibernate is an object-relational mapper that maps plain old CLR objects (POCOs) to database tables. It is based on Hibernate and provides a stable, database agnostic way to generate SQL at runtime. NHibernate configurations can be defined using XML, attributes or code-first fluent APIs. Sessions represent a lightweight transaction and identity mapping unit of work with the database. Entities are mapped to tables through properties, identifiers and relationships such as one-to-many, many-to-many and inheritance. Queries can be performed using the criteria API, HQL, LINQ or future queries to optimize performance. Caching at the session and query levels improves efficiency. NHibernate reduces
The document discusses Java input/output (I/O) streams. It covers byte streams like FileInputStream and FileOutputStream for reading and writing bytes. It also covers character streams like FileReader and FileWriter for reading and writing characters. Filtered streams like BufferedInputStream are discussed which add functionality to underlying streams. The document also covers random access files and the File class.
The document discusses various XML processing models including DOM, SAX, StAX, and VTD-XML. VTD-XML uses a non-extractive parsing approach that encodes tokens as 64-bit integers to provide efficient random access parsing of XML documents with minimal memory usage. It has advantages over DOM and SAX such as being faster, using less memory, and allowing incremental updates to XML documents. Parallel DOM (ParDOM) is also discussed as an approach to parallelize DOM parsing across multiple CPU cores.
Basic concepts of object oriented programmingSachin Sharma
This document provides an overview of basic concepts in object-oriented programming including objects, classes, data abstraction, encapsulation, inheritance, polymorphism, binding, and message passing. Objects are run-time entities with state and behavior, while classes define the data and behavior for objects of a similar type. Encapsulation binds data and functions within a class, while inheritance allows new classes to acquire properties of existing classes. Polymorphism enables one function to perform different tasks. Binding determines how function calls are linked, and message passing allows objects to communicate by sending requests.

Hibernate is an open source object-relational mapping tool that allows Java objects to be mapped to database tables. It allows developers to interact with a database using plain Java objects instead of SQL statements. Some key features of Hibernate include object-relational mapping, lazy loading of collections, polymorphic queries, and transaction management. Hibernate handles persistence by automatically storing and loading objects from a database.
Object-oriented databases (OODBMS) were developed to address limitations of the relational data model for representing complex real-world data. OODBs use objects with attributes and methods to model data, and support relationships like inheritance and containment between objects. They allow programming languages to represent data persistently in the database. However, OODBs have more limited query capabilities compared to relational databases.
Hibernate is an open source ORM tool that provides transparent persistence for Java objects (POJOs). It maps Java objects to relational database tables without requiring the developer to write SQL code.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

Where relational databases are unwieldy
The object database methodology
A brief introduction to Python
Mechanics of ZODB
Limitations

Individual Record Is Not Extensible
Extensible
Field
4. Issues with Relational DBs
Can’t store multiple values in a single field
Can’t add extra fields to individual records
Solved by adding extra relational tables
With complex data, this gets unmanageable
Developer time is wasted writing a database
interaction layer
6. Object Concepts
An object oriented database stores objects
instead of database records
Objects contain variables (data) and methods
to act on these variables; may be inherited
Objects are usually organised hierarchically
Most object databases are bound to a specific
language because each language implements
OOP differently
8. Why Python?
Python is a dynamic
typed and a strong
typed language
Python is dynamic:
everything can be
modified at runtime. Class
members, base
classes, whatever
10. What ZODB is Not
Not a relational database
No SQL support
No security model
No query interface:
Objects must be accessed via container
A separate search engine is available
12. Really Simple Usage
All classes must be derived from the
“Persistent” base class provided by ZODB
At the start of your program, open a ZODB
connection
Commit the transaction periodically
That is all!
Code need not be ZODB aware
13. Example Code
# Necessary imports
from ZODB import FileStorage, DB
from Persistence import Persistent
# Connect to a database
storage = FileStorage.FileStorage('/tmp/test-filestorage.fs')
db = DB(storage)
conn = db.open()
# Get the root of the database
dbroot = conn.root()
# Defining user classes
class UserDataClass(Persistent):
pass
# Commit or abort after making a change
get_transaction().commit()
get_transaction().abort()
14. Remote Storage: ZEO
ZEO is Zope Enterprise Objects
One ZEO serves multiple ZODB clients
Databases can be mounted on each other, just
like file systems
No replicated storage yet
15. Available ZODB Storages
FileStorage (standard)
The entire database is stored in a single file
DirectoryStorage
Each object is stored as a separate file
BerkeleyDB Storage
The database is stored in BerkeleyDB
ClientStorage
Database is stored in a remote ZEO database
16. Limitations
Only available via Python
Transparency is sometimes undesirable
Cannot detect changes in objects not derived
from the Persistent base class, like a list or
dictionary
Programmer has to flag such objects as dirty
ZEO is optimised for heavy reads, not writes
