PL/SQL is a combination of SQL along with the procedural features of programming languages.The PL/SQL programming language was developed by Oracle Corporation as procedural extension language for SQL and the Oracle relational database.Some of notable facts about PL/SQL: • PL/SQL is portable, high-performance transaction processing language. • PL/SQL provides a built in interpreted as well as OS independent programing environment. • PL/SQL can directly be called from the command line SQL-Plus interface. • Direct call can be made from external programming language calls to database. • PL/SQL's general syntax is based on that of ADA and Pascal programming language.
there are data dictionary management, data storage management, data transformation and presentation, security management, multiuser access control, backup and recovery management, data integrity management, database access languages and application programming interfaces, database communication interfaces, and transaction management. The first function of database management system is data dictionary. Database management system has been perform management functions to the elements in the database and how to connect the relationships with other data. When the system requires data in a database that will facilitate DBMS via SQL to access and search data. So that users can easily handle it.
As well as tables that include many application functions that directly connect with a client facing application. Getronics is a certified Microsoft Partner; therefore, Getronics uses Microsoft technology such as Microsoft SQL Server 2000. Microsoft SQL, or structured query language, is a standard interactive and programming language for getting information from and updating a database. (www.whatis.com) Every application that is developed or purchased by Getronics uses a SQL database as its backend office application. This standard application allows for development teams to design and implement applications and utilities that can integrate with one another.
Difference between DBMS and IRS by focusing on their functionalities. A Database Management System (DBMS) is a software system that uses a standard way of classifying, 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.
Client/Server Architecture and Attributes The client/server software architecture is a versatile, message-based and modular infrastructure that is intended to improve usability, flexibility, interoperability, and scalability as compared to centralized, mainframe, time sharing computing. A client is defined as a requester of services and a server is defined as the provider of services. A single machine can be both a client and a server depending on the software configuration. This technology description provides some common client/server architectures and attributes. The original PC networks were based on a file sharing architecture, where the server downloads files from the shared location to the desktop environment.
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 run on personal computers to large systems which run on mainframes.
It also contains great security because of the object based security model. MySQL MySQL is an open source relational database management system. It is built on the structure query language (SQL), which is used for inputting, deleting, and adjus... ... middle of paper ... ...ystem. 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 three features which support the database; Estimated Execution plan, Actual execution plan and Client Statistics.
SQL Server is an enterprise class RDBMS from Microsoft. It is part of the Back Office Suite of products. Although it is always server-based in production, it can be client-based in development. DB2 is also an enterprise-class DBMS, produced by IBM. It offers some object-oriented functionality, as well as cross-platform compatibility, and is server-based.
Third, I could improve my learning with even different favorable timings. With the knowledge gained I can able to develop applications using JDBC and also perform different operations which can be used to execute SQL commands. I also got knowledge of data centric applications.
It contains all the data definitions , report format and definitions of organizations which are related and system components. Database Management System- It is a commercial software system which is used to create , maintain and provide controlled access to the repository. Database - It is a collection of logically related data which is required to meet the needs of applications or users of organizations. SQL is a special purpose programming language designed for managing data held in relational database management systems(RDBMS).  1.
