Introduction: PL/SQL and T-SQL are completely different programming languages and have different variable declaration , different syntax, different built in- functions and programming capabilities. The only thing in common is they are extensions of SQL and the execution and storage inside the database. PL/SQL is a procedural language used for Oracle relational database where as T-SQL is a proprietary procedural language of used for Microsoft SQL server and Sybase. PL/SQL: PL/SQL stands for Procedure
Microsoft Language Integrated Query (LINQ) for SQL ie LINQ to SQL Introduction: This article is about LINQ (Language Integrated Query) which is one of the most entertaining concept and feature in .NET programming. LINQ makes the querying of data a unique programming concept in .NET. Querying of data can be taken from XML (LINQ to XML), database (LINQ enabled ADO.NET, LINQ to SQL, LINQ to Dataset, LINQ to Entities) and Object (LINQ to Objects). LINQ can easily and highly extensible and allow developers
Relational Database Management System Oracle provides a flexible RDBMS called Oracle7. Using its features, you can store and manage data with all the advantages of a relational structure plus PL/SQL, an engine that provides you with the ability to store and execute program units. The server offers the options of retrieving data based on optimization techniques. It includes security features that control how a database is accessed and used. Other features include consistency and protection of data
History of Database Technology Past and Present The term database was popularized with the growth of the computer industry and is typically thought of as software used to store, index, manipulate, and retrieve information (Vaughn). Database software has been in use since the Census Bureau used a punch card system to meet the requirements for the collection, sorting, and reporting of data for the 1890 census (National Research Council). These earliest databases were flat file databases. The
Database Management A database management system (DBMS) is computer software designed for the purpose of managing databases. Typical examples of DBMSs include Oracle, IBM's DB2, Microsoft Access, Microsoft SQL Server, MySQL, 4th Dimension and FileMaker. DBMSs are typically used by Database administrators in the creation of Database systems. DBMS enables the user to store, modify, and extract information from a database. There are many different types of DBMSs, ranging from small systems that
A proper physical database design is one of the most important steps that a database designer can complete to impact the overall performance of the database. When doing the physical database design it is important for the designer to understand what type of data is going to be included and how this data will be used. To better understand why this is important lets first break down a few of the basic elements that are important when completing the physical database design. One of the most basic
“Everyone thought you guys could not finish it, but you proved them wrong!” our supervisor said with pride after we demonstrated the term project for Object Oriented Programming Language Course. We chose to implement “Video Conferencing on Local Area Network”, while others thought it to be a preposterous choice for two first year students. It was the strongest feeling of achievement I felt that day, which only comes from overcoming a challenge with diligence and hard work. I relived the same feeling
Database is a collection of programs that enables users to create and maintain data. The other meaning, database some collection the related files that are usually included, concurrent referenced to one another. Good feature of a database is that data and records contains some in different files can be easily organized and save from harm in danger when using specialized database management software called a database management system (DBMS) or database manager. A database-management system (DBMS)
The Revolution in Database Architecture, by Jim Gray, describes the path that Gray thought that the evolution of the Database Architecture would take after 2004. He considers that databases had been stagnated for several years and that, beginning in 2004, the development of several technologies would pave the way into a revolution in the database world. The 14 technologies mentioned as the key for the revolution are: 1. The ability to execute Object Oriented code inside the RDBMS. 2. Databases

profession. The first issue to answer is the origin of the term unstructured data. The term is derived from a database technician cannot save data in a traditional schedule, and access data with SQL (Structured Query Language). Since the term in SQL is structured surgery, and the data cannot be retrieved from SQL, then those data must be unstructured clear. Works Cited • abhisyek Taneja. (2000). Types of Database System.

It is a full-featured database primarily designed to compete against competitors Oracle Database and MySQL. Some benefits to using SQL server are the seamless navigation which gives enough support for users to know how to work the system without asking an expert for assistance, it includes a query editor which is a tool used for executing T-SQL quires, which comes with the
retrieving, and running queries on data. The DBMS functions is to manage any incoming data, organize it, and provide ways for the data to be modified or extracted by users or other programs. Some examples of DBMS are PostgreSQL, Microsoft Access, SQL Server, FileMaker, Oracle,Clipper and FoxPro. Since there are so many database management systems are available, so it is important to ensure that they communicate with each other. This is because, most database software comes with an Open Database

Overview The purpose of this report is to examine the idea of transaction management and how it relates to two different database systems that I have chosen for the purpose of the project and for may research. I am also looking at the different elements with regard to transaction management and how each of them work and what they are for in the overall scheme that is transaction management. I will go through the definition of transaction the meaning of transaction how it functions the limitations
network and hierarchical database management systems was that they are the programmer’s domains. To answer the simplest query of this database, one had to create the program that navigated the database management structure and produce an output; unlike SQL, this program was written in the procedural, and required the great deal of the knowledge of both database management structure and underlying the operating system. As a result, these type of programs were not portable and took enormous amount of time
tiniest database development tools available for users and businesses. Businesses that are bigger and manage more quantities of data at a time, normally invest their money into more industrial database systems. These systems include IBM DB2, Microsoft SQL Server, and Oracle, and all of these database systems are much more commanding and pricey

database management systems (DBMS) that include the knowledge of Oracle, IBM DB2, and Microsoft SQL server (“Database Administrator,” 2010). Oracle is one of the most important platforms that DBA must know and have experience with. According to Kanaracus “The database experience we look for most of the time is Oracle”, says Tom Hart, executive vice president of the operations and technology group at Veritude. “SQL Server is more of a nice-to-have"
