Collections are objects that contain other objects and provide services like adding, removing, and managing elements. They can be implemented in many ways using abstract data types (ADTs) which define a standardized interface while hiding implementation details. Common collection classes in Java include ArrayList, LinkedList, sets, and maps. Dynamic data structures like linked lists can grow and shrink as needed by linking objects together through references.

Generics collections
This document discusses generics and collections in .NET. It introduces generics as a way to write reusable code for different data types. Generic methods and classes are covered, allowing a single definition to work with multiple types. The document also discusses collection classes like ArrayList, HashTable, Stack and Queue, which provide common data structures. It notes the benefits of generic collections over non-generic ones in terms of type safety and efficiency.
Comparable vs comparator
Comparable and Comparator interfaces in Java allow objects to be sorted. Comparable provides a natural ordering when implemented by a class, requiring it to override the compareTo() method. Comparator provides flexible sorting by having a separate class override the compare() method, allowing sorting based on different object attributes. The key differences are that Comparable defines the sorting logic within a class, while Comparator separates it out to an external class.
Vectors in Java
The program accepts 5 items from the command line and stores them in a Vector. It then demonstrates deleting an item, adding an item at a specified position, adding an item at the end, and printing the Vector contents. The Vector implements a dynamic array that can hold any type of objects and any number of elements. It is contained in the java.util package and is synchronized.
Generics C#
This document discusses generics in .NET. It introduces generics, generic classes, interfaces, structs and methods. Generics allow defining type-safe and reusable collection classes without compromising type safety or performance. Generic classes encapsulate operations that are not specific to a data type, commonly used for collections. Generic interfaces avoid boxing/unboxing for value types. Methods can also be generic with the ability to apply constraints.
Xtext: type checking and scoping
This document discusses type checking and scoping when working with entities in Xtend. It mentions creating an ExpressionTypeComputer class to check types of expressions and fields, including whether a field is of a basic type or entity type. It also discusses creating classes to handle scoping and visibility of fields within an entity hierarchy to allow references to fields of the current entity and super entities.
Collections (1)
The document discusses collections in programming and introduces some common collection classes. It explains that a collection gathers objects together and allows methods to manage the objects. Arrays have fixed sizes and require manual management, while collection classes are more flexible and remove disadvantages of arrays. Generic collection classes like List, Stack, and Queue provide type safety by only allowing objects of a specified type.
Bad smells in code
This document discusses code smells, which are signs of deeper problems in code that can negatively impact design quality and maintenance. It identifies several code smells including duplicated code, long methods, large classes, long parameter lists, divergent change, shotgun surgery, feature envy, data clumps, primitive obsession, switch statements, lazy class, speculative generality, temporary fields, and message chains. For each smell, it provides a brief refactoring recommendation such as extracting methods or classes to improve code structure, readability, and flexibility.
Unit 5
This document discusses abstract data types and encapsulation. It explains that abstract data types define a set of objects, operations on those objects, and encapsulate them so the user cannot directly access the hidden data. Encapsulation through subprograms and type definitions is described. Different approaches to static and dynamic storage management like stacks, heaps, and garbage collection are also summarized.
Standard template library
The document discusses the C++ Standard Template Library (STL). It provides an overview of STL containers, algorithms, iterators and how to access STL components. The main STL containers include vectors, lists, stacks, queues, priority queues, sets, multisets, maps and multimaps. Common operations on containers like insertion, deletion and traversal are also covered along with examples of how to declare and use iterators to access container elements.
Variable and constants in Vb.NET
1) Variables are used in programming to store and manipulate data values. They must be declared with a name and data type.
2) Variables can be initialized during or after declaration by assigning them a value. User input can be obtained and assigned to variables using functions like Console.ReadLine().
3) Constants are variables whose values cannot change once declared, while the scope of a variable determines where it can be accessed within a program.

3 sql overview
This document provides an overview of SQL, including:
1) SQL is a language used to work with databases in the "back end" and is not typically part of the user interface.
2) SQL standards were set in 1986 and allow for different levels of conformance between vendor implementations.
3) SQL is declarative rather than procedural, with code describing results rather than tasks, though it includes some procedural elements.
Normalization
Normalizing a database involves organizing data to:
1) Avoid duplicate values and inconsistent dependencies by separating data into multiple tables.
2) Ensure each table describes a single entity or "thing".
3) Achieve third normal form where data is organized into tables such that each non-key attribute is dependent only on the primary key.
SQL Constraints
This document discusses different types of constraints in a database including:
- Field constraints like NOT NULL, check, unique, primary key, foreign key
- Table constraints like check, unique, primary key, foreign key
- Examples of different constraints like required fields, check constraints using operators, ranges, lists, pattern matching, default values, unique, primary key, foreign key, and identity columns. It also discusses how to add, change, and drop constraints using ALTER and CREATE statements.

SELECT is used to retrieve data from database tables. The basic SELECT statement identifies the fields to retrieve using a field list, the table to select from, and optional clauses to filter rows by criteria, group data, and sort the results. Key clauses include FROM to identify the source table, WHERE to filter rows, GROUP BY to group rows, HAVING to filter groups, and ORDER BY to sequence the results. SELECT statements are typically used to query data and return it in a readable format.

This document discusses database design concepts including primary keys, foreign keys, relationships between tables, normalization, and different types of queries. It covers one-to-one, one-to-many, and many-to-many relationships and how to implement them. It also discusses referential integrity, data validation, indexes, anomalies that can occur without normalization, and different types of joins and queries.
CSS
Cascading Style Sheets (CSS) allow separation of document content from presentation through rules that control formatting and layout. A single CSS stylesheet can alter the appearance of multiple web pages, and different stylesheets can be used for a single page. CSS uses selectors, declarations, and properties to style elements. Stylesheets can be embedded within HTML documents or linked as external files, and support inheritance of styles. CSS treats elements as boxes and controls properties like margins, borders, padding, and positioning.
XPath
The document summarizes key concepts about XPath including:
1) XPath provides a logical model for working with XML documents and uses nodes to represent XML in memory.
2) XPath expressions can be absolute or relative and are used to select nodes from an XML document. Common axes include child, attribute, and descendant.
3) Predicates can be used to filter node sets and select specific nodes based on values or location.
XSLT Overview
This document provides an overview of XSL (eXtensible Stylesheet Language), which is used to transform and present XML documents. It discusses that XSL is made up of XSLT for transformations and XSL-FO for formatting. XSLT is a declarative language that describes the results of transforming an XML document rather than the steps. The document also outlines the basic process of applying XSL transformations using a stylesheet to match nodes and templates.
Views
This document discusses database views, which provide a virtual table that is not used for data storage. Views can reduce complexity, improve performance, and hide sensitive data. Indexed views can further improve performance by adding an index, but have additional requirements such as being deterministic and schema-bound. Views can also be updatable under certain conditions such as not including DISTINCT, TOP, aggregates, or a GROUP BY clause.
CIS282 Midterm review
The document discusses key concepts related to SQL Server databases including:
- SQL Server operates separately from client applications and requires a connection to transmit requests and responses.
- Management Studio is used to start/stop the SQL Server service and write/execute T-SQL statements.
- Databases contain tables, stored procedures, views, and indexes which are used to organize and retrieve data.
- Security is provided through login accounts and user roles within databases.
Schemas 2 - Restricting Values
The document discusses XML schemas and defines various XML schema components. It explains concepts like namespaces, element and attribute qualification, content models using sequence, choice, all and group, simple types with facets, and lists and unions. It provides examples of how to define elements and attributes with XML schemas by setting restrictions and patterns on data types.
CIS 145 test 1 review
This document provides an overview of key concepts for designing and working with relational databases, including:
- Databases store related data in tables, with common values creating relationships between tables.
- Tables contain records made up of related fields, and proper planning is needed to determine what data to include.
- Fields should be short but descriptive, and setting data types controls what values can be entered.
- Relationships can be one-to-one, one-to-many, or many-to-many, and referential integrity ensures consistency.
- Queries can look up related data automatically across tables.
XML schemas
XML schemas provide an alternative to DTDs for defining XML document structure and vocabulary. Schemas define a language through elements and datatypes. Unlike DTDs, schemas use XML for their own definition and support features like namespaces, inheritance, and data typing. When using a schema, XML documents must reference it to validate their structure and content.
Document type definitions part 2
This document discusses how to define elements and attributes in an XML document type definition (DTD). It explains how to specify an element's cardinality, or how many times it can occur. It also discusses using elements to describe logical units of information and attributes to store data about an element's characteristics. The document provides examples of common attribute data types like ID and IDREF and how to define enumerated lists for attributes. It explains how to declare entities for attributes and how to specify default, fixed, required, or implied values for attributes.
Document type definitions part 1
DTD stands for Document Type Definition and allows an XML document to specify requirements to be considered valid. A DTD defines allowable elements, attributes, and relationships between elements in an XML document. Validation ensures an XML document matches the DTD specifications. DTDs can be embedded locally in an XML file or referenced externally from a URI.
DOM specifics
The document discusses the Document Object Model (DOM) and its common interface members for manipulating XML and HTML documents. It describes how to create element nodes, text nodes, and attributes using the DOM interfaces. It also explains how to retrieve elements by tag name and access the properties and child nodes of elements.

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
