  • Chapter 9 Transact-SQL This Chapter Introduces the Many Options
    Transact-SQL Page 1 of 53 Chapter 9 Transact-SQL This chapter introduces the many options available for working with the SQL query language, along with the extensions and special features of Microsoft SQL Server/MSDE’s SQL dialect. The SQL standard was developed by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO). Today there are several standards whose names include the year in which they were released: SQL-89, SQL-92, and so on. The different standards vary in language functions and performance. Database vendors have fully or partially implemented the SQL standards in their products. Unfortunately, they have not yet agreed on a unified standard. Almost all have added their own extensions to the SQL implementations, so there are some significant differences among the SQL variations of individual products. Microsoft Access 2000 and Microsoft Access 2002 use Jet Engine 3.6—the database core for Access mdb databases—to support SQL-89 Level 1 with several extensions, as well as SQL-92 (albeit not completely) if you are using Jet Engine 4 with the ADO database interface. SQL Server/MSDE supports SQL-92, which for the most part conforms to the ANSI/ISO standard. The SQL language functions consist of two parts: The Data Definition Language (DDL) and the Data Manipulation Language (DML). With DDL, you can create, edit, and delete table structures and define indexes. The DML is used to query data or to edit and delete data. In Access, you usually only work with the DML, as tables and indexes are created with the tools available in Access.

  • Lab # 1 Introduction to Assembly Language
    Assembly Language LAB Islamic University – Gaza Engineering Faculty Department of Computer Engineering 2013 ECOM 2125: Assembly Language LAB Eng. Ahmed M. Ayash Lab # 1 Introduction to Assembly Language February 11, 2013 Objective: To be familiar with Assembly Language. 1. Introduction: Machine language (computer's native language) is a system of impartible instructions executed directly by a computer's central processing unit (CPU). Instructions consist of binary code: 1s and 0s Machine language can be made directly from java code using interpreter. The difference between compiling and interpreting is as follows. Compiling translates the high-level code into a target language code as a single unit. Interpreting translates the individual steps in a high-level program one at a time rather than the whole program as a single unit. Each step is executed immediately after it is translated. C, C++ code is executed faster than Java code, because they transferred to assembly language before machine language. 1 Using Visual Studio 2012 to convert C++ program to assembly language: - From File menu >> choose new >> then choose project. Or from the start page choose new project. - Then the new project window will appear, - choose visual C++ and win32 console application - The project name is welcome: This is a C++ Program that print "Welcome all to our assembly Lab 2013” 2 To run the project, do the following two steps in order: 1. From build menu choose build Welcome. 2. From debug menu choose start without debugging. The output is To convert C++ code to Assembly code we follow these steps: 1) 2) 3 3) We will find the Assembly code on the project folder we save in (Visual Studio 2012\Projects\Welcome\Welcome\Debug), named as Welcome.asm Part of the code: 2.

  • Migrating ASP to ASP.NET
    APPENDIX Migrating ASP to ASP.NET IN THIS APPENDIX, we will demonstrate how to migrate an existing ASP web site to ASP.NET, and we will discuss a few of the important choices that you must make during the process. You can also refer to the MSDN documentation at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/ html/cpconmigratingasppagestoasp.asp for more information. If you work in a ColdFusion environment, see http: //msdn. microsoft. com/library I default.asp?url=/library/en-us/dnaspp/html/coldfusiontoaspnet.asp. ASP.NET Improvements The business benefits of creating a web application in ASP.NET include the following: • Speed: Better caching and cache fusion in web farms make ASP.NET 3-5 times faster than ASP. • CompUed execution: No explicit compile step is required to update compo­ nents. ASP.NET automatically detects changes, compiles the files if needed, and readies the compiled results, without the need to restart the server. • Flexible caching: Individual parts of a page, its code, and its data can be cached separately. This improves performance dramatically because repeated requests for data-driven pages no longer require you to query the database on every request. • Web farm session state: ASP.NET session state allows session data to be shared across all machines in a web farm, which enables faster and more efficient caching. • Protection: ASP.NET automatically detects and recovers from errors such as deadlocks and memory leaks. If an old process is tying up a significant amount of resources, ASP.NET can start a new version of the same process and dispose of the old one.

  • Evoluzione Degli Strumenti Di Sviluppo Microsoft
    Evoluzione degli strumenti di sviluppo Microsoft Massimo Bonanni Senior Developer @ THAOS s.r.l. [email protected] http://codetailor.blogspot.com http://twitter.com/massimobonanni Agenda • Gli IDE questi sconosciuti • All’inizio era BASIC! • Anni ‘70-’80: compilatori e poco più • Anni ’90: frammentazione degli strumenti di sviluppo • Ultimi 10 anni: l’ecosistema .NET • Conclusioni IDE, questo sconosciuto • IDE è l’acronimo di Integrated Development Environment; • Un insieme di applicazioni (di solito abbastanza complesso) a supporto di chi produce software; • Generalmente consiste di: – Un editor di codice sorgente – Un compilatore e/o interprete – Un debugger – Un tool di building – Vari tools a supporto IDE, questo sconosciuto • Gli IDE possono essere multi-linguaggio o singolo linguaggio; • Alcuni IDE sono espandibili tramite plug-in o estensioni; • Negli ultimi anni gli IDE sono diventati parte di ecosistemi anche molto complessi che contemplano anche gestione del ciclo di vita delle applicazioni; IDE, a cosa serve Lo scopo di un IDE non è banalmente quello di permettere allo sviluppatore di scrivere codice ma dovrebbe permettere allo stesso di aumentare la propria produttività in tutti le fasi della realizzazione di un sistema software. IDE, a cosa serve In sintesi: “At every juncture, advanced tools have been the key to a new wave of applications, and each wave of applications has been key to driving computing to the next level.” Bill Gates La storia di Microsoft Possiamo suddividere l’evoluzione degli strumenti di sviluppo in tre fasi: – Anni ‘70-’80 : poco più che compilatori a riga di comando ed editor di base; – Anni ’90 : primi IDE a finestre (grazie all’arrivo di Windows); – Dal 2000 ad oggi: l’ambiente di sviluppo si trasforma in una vera piattaforma di sviluppo.
