Sql server ___________data control language
DCL is used to control permissions on database objects through statements like grant, revoke, and deny. Grant provides privileges to users to share access, revoke removes previously granted access, and deny prevents a user from inheriting permissions. These statements specify the permission, database object, and user account to manage what users can access.
Artifacts, Data Dictionary, Data Modeling, Data Wrangling
This document discusses different data modeling concepts including artifacts, data dictionaries, and data modeling. It defines artifacts as tangible byproducts of software development that help describe functions, architecture, and design. Data dictionaries are described as databases containing metadata about the data stored in other databases, including information like field sizes and data authorization. Different types of data models are presented, including conceptual, logical, and physical models, with conceptual being most abstract and physical being database specific. The document also discusses data wrangling as the process of cleaning, structuring, and enriching raw data.
Database note for 4th semester Notes
A database is a collection of logically related data designed to meet the information needs of an organization. It includes entities, attributes, and relationships. A database management system (DBMS) enables users to define, create, maintain, and control access to the database. It allows application programs to interact with the database using queries. Key components of a DBMS environment include hardware, software, data, procedures, and users who have different roles. DBMSs provide advantages like data sharing and integrity but also disadvantages like complexity, costs, and potential single points of failure.
Database Session
The document discusses the basics of databases including what a database is, why they are used, different types of databases, keys and normalization. It also covers database engines like Microsoft Access and MySQL, the structured query language SQL for accessing and modifying relational databases, and data manipulation language commands like SELECT, INSERT, UPDATE, and DELETE. The document provides an overview agenda for learning the beginners approach to working with MUFIX community databases.
Chapter 7 relation database language
This document discusses the SQL language for relational databases. It covers the background and history of SQL, the SQL standards, and the key statements and features of SQL including data definition, data types, schema and table creation, attributes, constraints, keys and referential integrity. The document provides examples of SQL statements and clauses to define schemas, tables, attributes, primary keys, foreign keys and other constraints.
Introductin to Data Modeling.
This document provides an introduction to data modeling. It defines data models as precise descriptions of data content in a system, including conceptual, logical, and physical models. Data models are created to develop sound database designs that avoid anomalies. Common types are entity-relationship models and UML class models. The key steps in entity-relationship modeling are identifying entities and their attributes/primary keys, and specifying relationships between entities. The document also discusses design considerations for attributes such as whether they are atomic, composite, multi-valued, or derived.

Chapter 3 Entity Relationship Model
This document discusses database design using Entity Relationship Diagrams (ERDs). It covers how to draw ERDs using Chen's Model and Crow's Foot notations and define the basic elements of ERDs. Conversion rules are presented to convert ERDs into relational tables for one-to-one, one-to-many, and many-to-many relationships. An example is given to demonstrate drawing an ERD for a company database and converting it into relational tables.
Database model
1) A data model abstracts the essential qualities of a dataset and describes the data in an organization. It involves determining user and application data requirements and integrating them into an overall conceptual view.
2) Conceptual and physical data models are created. The conceptual model specifies data for human understanding while the physical model aids database design.
3) Data modeling defines entities, attributes, relationships and identifies primary keys. It also establishes constraints and referential integrity rules for the data.
Nayana
The document discusses key characteristics of database systems including:
1) Database systems contain a complete definition of the database structure and constraints stored in the database management system (DBMS) catalog.
2) The DBMS catalog allows different databases to be accessed while insulating application programs from changes to data structure.
3) Database systems support multiple views of data including virtual views derived from stored data.
The three level of data modeling
The document compares conceptual, logical, and physical data models. Conceptual models show entities and relationships without attributes or keys. Logical models add attributes, primary keys, and foreign keys. Physical models specify tables, columns, data types, and foreign keys to represent the database implementation. The complexity increases from conceptual to logical to physical models.
Chapter10 conceptual data modeling
This document discusses conceptual data modeling and Entity-Relationship diagrams. It defines key terms like entities, attributes, relationships and cardinality. It explains how to represent these concepts in ER diagrams and discusses best practices for naming relationships and defining domains. The goals of conceptual data modeling are to accurately represent organizational data and rules through diagrams and establish consistency between the data, process and logic models.

Theory of Relational Database.pptx 0.84 Mb
Relational databases organize and store structured data in tables that represent relationships between entities. Tables contain rows and columns, with rows holding unique record sets and columns defining attribute types. Keys uniquely identify records and link tables, establishing relationships that are fundamental to relational databases. Relationships are created using keys and include one-to-one, one-to-many, and many-to-many associations to maintain data integrity. Relational databases also use normalization, SQL, flexibility, scalability, and ACID properties.

Development of a new indexing technique for XML document retrieval
The document proposes a new indexing technique for XML document retrieval that addresses issues with existing techniques. It represents an XML document as a tree structure with nodes corresponding to elements, attributes, and content. Nodes are labeled with start/end positions and level to allow efficient updates by leaving gaps between labels. The technique permits fast retrieval of ancestor-descendant and parent-child relationships without recomputing the index on updates. Future work could include indexing comments and handling two separate indices for updates and queries.
Data mining query languages
The document discusses three approaches to integrating data mining capabilities with database systems: DMQL, MSQL, and OLE DB for DM. All three aim to allow users to define, populate, and query data mining models through SQL-like interfaces. DMQL focuses on specifying rules to discover. MSQL provides an expressive language for generating and querying association rules. OLE DB for DM supports defining models, populating them from training data, and using the models to predict attributes via a prediction join. An ideal solution would support defining models, querying model results, and applying models to new data within the database system.

CSS saves a lot of work by enabling web developers to change the appearance and layout of multiple pages at once by editing just one CSS file. CSS solves the problem of formatting documents that originally arose with HTML by separating document content from document presentation.
Kelompok 2 waterfall
Waterfall adalah metodologi pengembangan perangkat lunak secara sistematis dan sekuensial melalui tahapan analisis, desain, pengkodean, pengujian, dan pemeliharaan. Metode ini mudah diaplikasikan namun sulit mengakomodasi perubahan dan ketergantungan antartahap menyebabkan penundaan.
Kelompok 3 incremental
Metode pengembangan sistem incremental merupakan model pengembangan perangkat lunak yang membagi persyaratan menjadi beberapa fungsi atau bagian sehingga pengembangannya dilakukan secara bertahap. Model ini memiliki tahapan requirement, spesifikasi, desain arsitektur, pengkodean, dan pengujian. Metode ini cocok untuk sistem yang terus berkembang dan proyek berukuran kecil.
Tugas 1 (inventory)
Persediaan (inventory) adalah stok barang atau komponen yang disimpan untuk tujuan produksi atau penjualan. Ada beberapa alasan untuk mempertahankan persediaan, seperti mengantisipasi lonjakan permintaan, mencapai skala ekonomi, dan mempertimbangkan waktu pengiriman. Manajemen persediaan yang tepat diperlukan untuk menghindari kelebihan atau kekurangan stok yang dapat mengganggu produksi.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.Must Know Postgres Extension for DBA and Developer during Migration

GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
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.
