Collections Framework is a unified architecture for managing collections, Main Parts of Collections Framework
1. Interfaces :- Core interfaces defining common functionality exhibited by collections
2. Implementations :- Concrete classes of the core interfaces providing data structures
3. Operations :- Methods that perform various operations on collections
Servlet is java class which extends the functionality of web server by dynamically generating web pages.
Servlet technology is used to create Dynamic web application. Servlet technology is robust and scalable. init() and service() methods are more important in life cycle of a servlet. doGet() and doPost() are methods used under service() method.
What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.

SharePoint is from Mars, SQL Server is from Venus (SQL Server for SharePoint ...Mark Broadbent
The SQL Server Database Engine is a prerequisite and fundamental part of any SharePoint deployment but the downside to all of this is the Database Server usually brings a Database Administrator with it. In this session we will explain how to configure SQL Server correctly with SharePoint deployments in mind, how the underlying architecture and mechanisms of SQL Server work and why you need to do all this! By the end of this session you will have learnt how to talk to your DBA to explain that they are doing it wrong!

Is SQLcl the Next Generation of SQL*Plus?Zohar Elkayam
Session from ILOUG I presented in May, 2016
Introducing the new tool from the developers of SQL Developer: SQLcl – a new command line tool from the SQL Developer team that might replace SQL*Plus and all of its functions which has been around for over 30 years!
In this session, we will explore the new functionality of the SQLcl, and use a live demonstration to show what SQLcl has to offer over the old SQL*Plus. We will use real life example to see what makes this tool such a time saver in day-to-day tasks for DBAs and developers who prefer using the command line interface.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

4. SQLite is…
• in-process library
• self-contained
• serverless
• zero-configuration
• transactional
• the code is in the public domain
5. in-process library
• SQLite does not have a separate server process
• the library size can be less than 350KiB!
• SQLite be made to run in minimal stack space
(4KiB)transactional
• SQLite generally runs faster the more memory
you give it!
6. Self-contained
• It requires very minimal support from external
libraries
• It requires very minimal support from the
operating system
• The only required C library functions called are:
• memset()
• memcpy()
• memcmp()
• strcmp()
• malloc(), free(), and realloc()
7. Serverless
• Most SQL database engines are implemented as a separate server
process. Programs that want to access the database communicate with
the server using some kind of interprocess communication (typically
TCP/IP) to send requests to the server and to receive back results. SQLite
does not work this way. With SQLite, the process that wants to access the
database reads and writes directly from the database files on disk. There
is no intermediary server process.
• The main advantage is that there is no separate server process to install,
setup, configure, initialize, manage, and troubleshoot.
• Any program that is able to access the disk is able to use an SQLite
database.
8. Zero configuration
• SQLite does not need to be "installed" before it is
used.
• There is no "setup" procedure.
• There is no server process that needs to be
started, stopped, or configured.
• SQLite uses no configuration files.
SQLite just works.
9. Transactional
• SQLiteimplements serializable transactions that are atomic, consistent, isolated,
and durable (ACID).
• All changes within a single transaction in SQLite either
occur completely or not at all, even if the act of writing the
change out to the disk is interrupted by
• a program crash,
• an operating system crash, or
• a power failure.
10.
11. Features
• Implements most of SQL92.
• RIGHT and FULL OUTER JOIN
• Only the RENAME TABLE and ADD COLUMN variants of the ALTER TABLE
• VIEWs in SQLite are read-only.
• Supports terabyte-sized databases and gigabyte-
sized strings and blobs.
• Faster than popular client/server database
engines for most common operations.
• Cross-platform: Unix (Linux, Mac OS-X, Android,
iOS) and Windows (Win32, WinCE, WinRT)
12.
13. Suggested Uses
• Database For Gadgets
• cellphones, PDAs, MP3 players
• Website Database
• Internal or temporary databases
14. Applications that use it
• Browsers
• Mozilla Firefox (bookmarks, cookies, contacts)
• Google Chrome
• Opera
• Applicazioni
• Skype
• Adobe AIR
• Flame (anche gli hakers lo usano!)
• SpiceWorks (software per sistemisti e help desk)
