Insert Statement
The INSERT INTO statement is used to insert new records into database tables. It supports two methods: the implicit method inserts values into selected fields, specifying the field names, while the explicit method inserts values into all fields without specifying field names. Both methods are demonstrated with examples inserting records into a sample STUDENT table using different syntax depending on the selected method.

Need of object oriented programming
Object oriented programming (OOP) addresses limitations of procedural programming by dividing programs into objects that encapsulate both data and behaviors. OOP supports features like inheritance, polymorphism, and abstraction. Inheritance allows new classes to inherit attributes and behaviors from parent classes, polymorphism allows the same message to be interpreted differently depending on the object receiving it, and abstraction focuses on essential characteristics without implementation details. These features help make programs more modular, reusable, and maintainable.

Ruby on rails evaluation
Ruby on Rails provides a default model-view-controller design and generators that apply progressive evaluation and domain correspondence. The code completion in the IDE and Ruby language has issues with penetrability. Migrations offer a high-level abstraction for data modeling through specialized Ruby files that are invertible and treat objects rather than records. Rails leverages the dynamic Ruby language to provide good domain correspondence, progressive evaluation, and abstraction level, though it is missing error prevention due to the dynamic approach.
Design patterns
This document discusses several design patterns including Singleton, Observer, Delegation, Adapter, Facade, Immutable, Read-Only Interface, Proxy, and Factory. For each pattern, the document describes the context, problem, forces, and solution. The patterns provide reusable solutions to common programming problems by separating interfaces from implementations.
Lisp and scheme i
Lisp and Scheme are dialects of the Lisp programming language. Scheme is favored for teaching due to its simplicity. Key features of Lisp include S-expressions as the universal data type, functional programming style with first-class functions, and uniform representation of code and data. Functions are defined using DEFINE and special forms like IF and COND control program flow. Common list operations include functions like CAR, CDR, CONS, LIST, and REVERSE.
Ado.net & data persistence frameworks
The document discusses serialization, ADO.NET, data tier approaches, and persistence frameworks. Serialization allows persisting an object's state to storage and recreating it later. ADO.NET provides classes for connecting to and interacting with databases. Common data tier approaches include presenting data directly to the presentation layer, adding a business logic layer, or adding a service layer between business logic and data access. Persistence frameworks aim to simplify data access by encapsulating object persistence behaviors like reading, writing, and deleting objects from storage.
Multithreading models.ppt
The document discusses three common multithreading models: many-to-one, one-to-one, and many-to-many. It also describes common high-level program structures for multithreaded programs like the boss/workers model, pipeline model, up-calls, and using version stamps to keep shared information consistent.
Business analytics and data mining
The document provides an overview of business analytics (BA) including its history, types, examples, challenges, and relationship to data mining. BA involves exploring past business performance data to gain insights and guide planning. It can focus on specific business segments. Types of BA include reporting, affinity grouping, clustering, and predictive analytics. Challenges to BA include acquiring high quality data and rapidly processing large volumes of data. Data mining is an important part of BA, helping to sort and analyze large datasets.
Big picture of data mining
This document discusses decision trees and how they are constructed. It begins by explaining that decision trees use supervised learning to generate classification rules by splitting a training dataset based on attribute values. It then walks through an example of constructing a decision tree for predicting voter support based on attributes like age, income, education level, etc. The document discusses that the optimal way to construct a decision tree is NP-complete, so heuristics like information gain are used to choose the best attribute to split on at each node to minimize complexity. It concludes by adding a new social security number attribute and explaining that information gain would not choose to split on this attribute.
Data mining and knowledge discovery
The document discusses data mining and knowledge discovery from large datasets. It begins by defining the hierarchy from data to wisdom. It then discusses the growth of big data from various sources and the need for data mining to extract useful knowledge. Data mining involves applying machine learning, statistics, visualization and database techniques to discover patterns in large datasets. The knowledge discovery process involves data cleaning, transformation, data mining and evaluating/interpreting patterns. The document provides examples of data mining applications in business, fraud detection, text mining and web mining.
Cache recap
The document discusses memory hierarchy and caching techniques. It begins by explaining the need for a memory hierarchy due to differing access times of memory technologies like SRAM, DRAM, and disk. It then covers concepts like cache hits, misses, block size, direct mapping, set associativity, compulsory misses, capacity misses, and conflict misses. Finally, it discusses using a second-level cache to reduce memory access times by capturing misses from the first-level cache.
Directory based cache coherence
The document discusses non-uniform cache architectures (NUCA), cache coherence, and different implementations of directories in multicore systems. It describes NUCA designs that map data to banks based on distance from the controller to exploit non-uniform access times. Cache coherence is maintained using directory-based protocols that track copies of cache blocks. Directories can be implemented off-chip in DRAM or on-chip using duplicate tag stores or distributing the directory among cache banks. Examples of systems like SGI Origin2000 and Tilera Tile64 that use these techniques are also outlined.
Hardware managed cache
The document proposes optimizing DRAM caches for latency rather than hit rate. It summarizes previous work on DRAM caches like Loh-Hill Cache that treated DRAM cache similarly to SRAM cache. This led to high latency and low bandwidth utilization.
The document introduces the Alloy Cache design which avoids tag serialization to reduce latency. It also proposes a Memory Access Predictor to selectively use parallel or serial access models for low latency and bandwidth. Simulation results show Alloy Cache with a predictor outperforms previous designs like SRAM-tag caches. The design provides benefits with simple structures optimized for DRAM cache constraints.
How analysis services caching works
This document discusses how Analysis Services caching works and provides strategies for warming the Storage Engine cache and Formula Engine cache. It explains that the Storage Engine handles data retrieval from disk while the Formula Engine determines which data is needed for queries. Caching can improve performance but requires understanding when Analysis Services is unable to cache data. The document recommends using the CREATE CACHE statement and running regular queries to pre-populate the caches with commonly used data. Memory usage must also be considered when warming the caches.
Abstract data types
This document discusses abstract data types (ADTs) and their implementation in various programming languages. It covers the key concepts of ADTs including data abstraction, encapsulation, information hiding, and defining the public interface separately from the private implementation. It provides examples of ADTs implemented using modules in Modula-2, packages in Ada, classes in C++, generics in Java and C#, and classes in Ruby. Parameterized and encapsulation constructs are also discussed as techniques for implementing and organizing ADTs.
Optimizing shared caches in chip multiprocessors
Chip multiprocessors, which place multiple processors on a single chip, have become common in modern processors. There are different approaches to managing caches in chip multiprocessors, including private caches for each processor or shared caches. The optimal approach balances factors like interconnect traffic, duplication of data, load balancing, and cache hit rates. Recent research explores techniques like cooperative caching between private caches and adaptive set pinning in shared caches.
Api crash
This document provides an overview of APIs, including what they are, why they are useful, common data formats like JSON and XML, RESTful API design principles, and how to consume and create APIs. It discusses API concepts like resources, HTTP verbs, caching, authentication, and error handling. It also provides examples of consuming APIs with tools like Postman and creating a simple API in Node.js.
Object model
The document discusses abstraction, which is a fundamental concept of object-oriented design. Abstraction involves focusing on an object's essential characteristics and behavior while hiding implementation details. There are different types of abstractions from most useful to least useful. Effective abstractions model real-world entities and provide well-defined interfaces through contracts, preconditions, and postconditions. Both static and dynamic properties of objects must be considered.
Abstraction file
This document discusses the key concepts of object-oriented programming including abstraction, encapsulation, classes and objects. It defines abstraction as focusing on the essential characteristics of an object and hiding unnecessary details. Encapsulation hides the internal representation of an object within its public interface. A class combines both abstraction and encapsulation, defining the data and operations of an object. Objects are instantiations of classes that are initialized via constructors and cleaned up via destructors.
Object oriented analysis
Object-oriented analysis and design (OOAD) emphasizes investigating requirements rather than solutions, and conceptual solutions that fulfill requirements rather than implementations. OOAD focuses on identifying domain concepts and defining software objects and how they collaborate. The Unified Process includes inception, elaboration, construction, and transition phases with iterations and milestones leading to final product releases.
Abstract class
Abstract classes and interfaces allow for abstraction and polymorphism in object-oriented design. Abstract classes can contain both abstract and concrete methods, while interfaces only contain abstract methods. Abstract classes are used to provide a common definition for subclasses through inheritance, while interfaces define a contract for implementing classes to follow. Both support polymorphism by allowing subclasses/implementing classes to determine the specific implementation for abstract methods.
Concurrency with java
This document discusses various programming paradigms and concurrency concepts in Java. It covers single process and multi-process programming, as well as multi-core and multi-threaded programming. The document also discusses processes, threads, synchronization, deadlocks, and strategies for designing objects to be thread-safe such as immutability, locking, and splitting state.

High performance Serverless Java on AWS- GoTo Amsterdam 2024
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.
Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

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?

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

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.
