Structured Query Language (SQL) is a computer language which is used for managing and manipulating data in relational databases. SQL helps the application to communicate with the database. Copy the link given below and paste it in new browser window to get more information on SQL:- www.transtutors.com/homework-help/computer-science/sql.aspx
MS SQL Server is a database server produced by Microsoft that enables users to write and execute SQL queries and statements. It consists of several features like Query Analyzer, Profiler, and Service Manager. Multiple instances of SQL Server can be installed on a machine, with each instance having its own set of users, databases, and other objects. SQL Server uses data files, filegroups, and transaction logs to store database objects and record transactions. The data dictionary contains metadata about database schemas and is stored differently in Oracle and SQL Server.
The document provides an overview of SQL Server including:
- The architecture including system databases like master, model, msdb, and tempdb.
- Recovery models like full, bulk-logged, and simple.
- Backup and restore options including full, differential, transaction log, and file group backups.
- T-SQL system stored procedures for administration tasks.
- SQL commands and functions.
- SQL Agent jobs which are scheduled tasks consisting of steps to perform automated tasks.
The document discusses legacy connectivity and protocols. It describes legacy integration as integrating J2EE components with legacy systems. The key approaches to legacy integration are data level integration, application interface integration, method level integration, and user interface level integration. Legacy connectivity can be achieved using Java Native Interface (JNI), J2EE Connector Architecture, and web services. JNI allows Java code to call native methods written in other languages like C/C++. The J2EE Connector Architecture standardizes connectivity through resource adapters. Web services provide a platform-independent approach through XML protocols.
The document discusses various disaster recovery strategies for SQL Server including failover clustering, database mirroring, and peer-to-peer transactional replication. It provides advantages and disadvantages of each approach. It also outlines the steps to configure replication for Always On Availability Groups which involves setting up publications and subscriptions, configuring the availability group, and redirecting the original publisher to the listener name.
The document introduces Test Driven Development (TDD), Continuous Integration (CI), Inversion of Control (IoC), and Aspect Oriented Programming (AOP). It discusses TDD principles and tools for writing tests first before code. CI aims to integrate code changes frequently to prevent integration problems. IoC and dependency injection improve software design by reducing coupling between components. AOP allows cross-cutting concerns like logging to be coded separately from the main program logic.

IBM has substantial operations in many countries, including the United States, Canada, and Germany. Go to finance.yahoo.com/q?s=ibm.
1. Click on Historical Prices. (Or apply this exercise to a different MNC.) Set the date range so that you can obtain quarterly values of the U.S. stock index for the last 20 quarters. Insert the quarterly data on a spreadsheet. Compute the percentage change in IBM’s stock price for each quarter. Next go to finance.yahoo.com/stock-center/ and click (under U.S.) on S&P Composite 1500 Index, which represents the U.S. stock market index, so that you can derive the quarterly percentage change in the U.S. stock index over the last 20 quarters. Then run a regression analysis with IBM’s quarterly return (percentage change in stock price) as the dependent variable and the quarterly percentage change in the U.S. stock market’s value as the independent variable. (Appendix C explains how Excel can be used to run regression analysis.) The slope coefficient serves as an estimate of the sensitivity of IBM’s value to the U.S. market returns. Also, check the fit of the relationship based on the R-squared statistic.
2. Go to finance.yahoo.com/stock-center/ and click (under “Europe”) on DAX, which represents the German stock market index. Repeat the process described in exercise 1 so that you can assess IBM’s sensitivity to the German stock market. Compare the slope coefficient between the two analyses. Is IBM’s value more sensitive to the U.S. market or the German market? Does the U.S. market or the German market explain a higher proportion of the variation in IBM’s returns (check the R-squared statistic)? Offer an explanation of your results.

Taming startup dynamics - Magnus Jungsbluth & Domagoj Cosicmfrancis
OSGi Community Event 2016 Presentation by Magnus Jungsbluth & Domagoj Cosic (Bundesdruckerei GmbH)
If you had to name a single great thing about OSGi, it would probably be its dynamics. Services come and go; other services react to those events, configuration can change and so on. Even the startup is dynamic: start levels are increased synchronously; however, configuration, Declarative Services, and Blueprint are started asynchronously after bundles turn active. We love that but sometimes you want to exercise control over when your application is actually fully started or more importantly when it is not. You certainly do not want your system to be accessible with a security module that threw an exception during startup. Unlike monolithic applications, an OSGi application behaves more like a distributed system that converges to a final state eventually.
We will show you a way to monitor startup of your application by creatively using some common OSGi mechanisms and demonstrate failure scenarios for common subsystems like configuration and Blueprint. We will also demonstrate the concept of start phases which are a higher-level concept on top of OSGi start levels. A phased start enables a higher level of security in the face of failures during startup.

IBM Informix dynamic server 11 10 Cheetah Sql FeaturesKeshav Murthy
The document summarizes new features in Informix Dynamic Server (IDS) version 11.10. Key features include:
1) Full support for subqueries in the FROM clause of SQL statements and enhancements to distributed queries.
2) New data types like Node and Binary, and a basic text search index for full text search capabilities.
3) Performance improvements to the SQL optimizer including an index self-join access method and directives for ANSI joins.
4) Enhancements to stored procedures, functions, isolation levels and utilities like SYSDBOPEN and SYSDBCLOSE.
This document discusses how to manage data in tables using SQL. It covers creating rules and defaults to enforce constraints without changing the table structure. It also covers using INSERT, UPDATE and DELETE statements to maintain data in tables. Specifically, it provides examples of creating a rule to enforce a zip code format, creating a default value for a country code, and inserting a new record into the RecruitmentAgencies table.
The document discusses exception handling and templates in C++. It describes exception handling using try, catch, and throw keywords. It also explains function templates and class templates which allow creating generic functions and classes that can work with different data types.
Triggers are database objects that are executed automatically in response to data modification statements like INSERT, UPDATE or DELETE on a table. There are different types of triggers - BEFORE triggers execute before the triggering statement while AFTER triggers execute after. Triggers can be used for data validation, integrity, auditing and more. Views can have INSTEAD OF triggers that allow modifications to views to be redirected to base tables.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
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).
