The three phases of database design are conceptual, logical, and physical. The conceptual phase involves defining the entities, attributes, and relationships without considering implementation details. The logical phase maps the conceptual model to a relational schema and defines data types and constraints. The physical phase involves storage, indexing, and other implementation details to optimize performance and manage resources. Some examples of normalization problems are redundant or inconsistent data. Functional dependencies enforce that values in one set of columns uniquely determine values in another set of columns to reduce anomalies. Transactions ensure integrity by grouping related operations that must all complete fully or none at all through properties like atomicity, consistency, isolation, and durability.

3 where are my keys - sql explore
The document discusses the principles of relational databases including normalization rules, key selection, and debates around these topics. It covers 1st, 2nd, and 3rd normal form, different types of keys like simple, composite, candidate and primary keys, and debates around using natural versus artificial keys as the primary key. It also mentions less discussed issues like data statistics and modularity. The document aims to revisit these foundational database concepts from a practical perspective and includes examples in the discussion.
Frequently asked tcs technical interview questions and answers
This document provides information about the interview process and sample technical questions for a job interview at TCS, an IT company. It describes the different types of interviews - campus interviews which are 45-60 minutes with one or more interviewers focusing on communication skills and background, and phone interviews which assess similar areas. It then provides examples of 20 technical questions that may be asked, covering topics like programming languages, data structures, OOP concepts, and more. Sample answers are provided for some of the questions.
Effective Unsupervised Matching of Product Titles
The conference presentation of the article:
L. Akritidis, P. Bozanis, "Effective Unsupervised Matching of Product Titles with k-Combinations and Permutations", In Proceedings of the 14th IEEE International Conference on Innovations in Intelligent Systems and Applications (INISTA), pp. 1-10, 2018.
which was presented in Thessaloniki, Greece in 2018.
Dbms 10: Conversion of ER model to Relational Model
The document discusses the conversion of an entity-relationship (ER) model to a relational model by describing how different ER constructs such as strong/weak entities, relationships, composite/multi-valued attributes, generalization/specialization, and aggregation map to relational schemas and tables. Strong entities become tables with their primary key and attributes, while weak entities include the primary key of their identifying entity. Relationships become tables linking the participating entity primary keys. Descriptive attributes may also be included.
Point to point.48
This document discusses point-to-point and point-to-multipoint networks. It defines point-to-point networks as connections between two end points, usually host computers. Point-to-multipoint networks connect a single location to multiple locations. The document describes basic point-to-point data links using RS-232 interfaces and modems, as well as modern wireless point-to-point links. It explains that point-to-multipoint networks divide bandwidth from a central hub among multiple connected nodes and are commonly used for wireless internet and IP telephony.
Layers of tcpip.65 to 66
The document describes the layers of the TCP/IP network model and the protocols used in each layer. It discusses the four layers - host-to-network, internet, transport, and application layers. The host-to-network layer deals with the physical transmission medium. The internet layer uses the IP protocol for packet routing. The transport layer contains the TCP and UDP protocols, where TCP provides reliable connections and UDP provides fast delivery. The application layer supports protocols like HTTP, SMTP, and NNTP.
Interrupt1
Interrupts can be useful for time critical applications, performing routine tasks, task switching in multi-tasking applications, and servicing peripheral devices quickly. The document also lists register and bit definitions for the RCON, INTCON3, PIR1 and PIR2 registers related to interrupts.
Networks 1-intro
This document provides an overview of an introduction to computer networks lecture. It outlines the topics to be covered, including an introduction to networks, layered architecture, routing, reliable transmission, flow control, and congestion control. It then discusses what a network is, how infrastructure is shared, circuit switching versus packet switching, best effort service, analogies to the mail system, and characteristics of the Internet's best effort service such as variable delay, packet loss and reordering. It compares the guarantees and efficiencies of circuit switching versus packet switching.

Question 1. 1. (TCO 1) A DBMS performs several important functions that guarantee the integrity and consistency of the data in the database. Which of the following is NOT one of those functions?
Techpaper
This document discusses design patterns for small devices. It begins by introducing design patterns as recurring solutions to software design problems. It notes that the process of building software should be evolutionary, learning from past experiences. The objective is to apply this theory to embedded systems and suggest three design patterns: Hierarchical State, Virtual Component, and LED Error patterns. It then provides details on each of these patterns, including their structure, implementation, applicability and known uses. The Hierarchical State pattern addresses complexity in state machine designs by organizing states hierarchically. The Virtual Component pattern reduces memory usage by loading components on demand. The LED Error pattern standardizes error handling across modules.
