In an SQL database like MySQL, Sybase, Oracle, or IBM DM2, SQL executes queries, retrieves data, and edits data by updating, deleting, or creating new records. SQL is a lightweight, declarative language that does a lot of heavy lifting for the relational database, acting like a database’s version of a server-side script. One particular advantage of SQL is its simple-yet-powerful JOIN clause, which allows developers to retrieve related data stored across multiple tables with a single command. POPULAR SQL DATABASES AND RDBMS’S • MySQL—the most popular open-source database, excellent for CMS sites and blogs. • Oracle—an object-relational DBMS written in the C++ language.
Windows NT has both positives and negatives. Some of the advantages include: Integration Performance Reliability Security Manageability Internet Access. Windows NT Server allows all applications to be utilized from the Windows NT Directory Service or NTDS. This has a network logon to all servers and services that it provides and its advantage: Only one user database is needed for the whole system. Windows NT also allows integration with other hardware and operating systems; and files and applications from other servers such as Unix and NetWare.
Oracle Corporation produces products and services to meet your relational database management system needs. The main product is the Oracle Server, which enables you to store and manage information by using SQL and the PL/SQL engine for procedural constructs. SQL The Oracle Server supports ANSI standard SQL and contains extensions. SQL is the language used to communicate with the server to access, manipulate, and control data. PL/SQL The PL/SQL language extends the SQL language by offering block-structured procedural constructs combined with SQL nonprocedural capabilities.
Some DBMS examples include MySQL, PostgreSQL, Microsoft Access, SQL Server, FileMaker, Oracle, RDBMS,dBASE, Clipper and FoxPro. A database application is a set of one or more computer programs that serves as an intermediary between the user and DBMS. This application can read or modify the database by sending SQL statements to the DBMS. It also presents the data to the user in the format of forms and report. It also can be acquired from the software vendor, and they are also frequently written in-house.
Licensing Much like the upgrade from Microsoft Windows Server 2003 to Microsoft Windows Server 2008, the organization can benefit from upgrading the Micro Widgets, Incorporated environment from Microsoft Windows Server 2008 to Microsoft Windows Server 2012. The first benefit involves licensing. While there are four versions available: Datacenter, Standard, Essentials and Foundation, only two of the versions of Server 2012, Datacenter and Standard, really matter to an enterprise the size of Micro Widgets, Incorporated. Licensing for the two versions involves both a processor license as well as a Client Access License (CAL). Selecting the correct version to suit this organization’s needs comes down to one key difference.
The operating system (OS) is a collection of software to control the computer tasks and manage proper utilization of the hardware resources. The basic operating systems are the Linux, UNIX, Mac and Microsoft Windows. There are several and diverse components of an operating system that include but not limited to the file management, security, memory and process management. The following paragraphs present the comparison of basic operating systems with respect to the above given features (Solomon, Russinovich & Polze, 2006). The file management system refers to the organization, management and manipulation of computer data in documents and files that is provided by the file manager through a graphical user interface.
Operating system can be found on almost on any device that contains a computer – from cellular phones and video game consoles to supercomputers and servers. Examples of modern operating systems include Android, iOS, Linux, Microsoft windows, Windows Phone and IBM z/OS. All these, except windows, windows phone and IBM z/OS share roots in Unix. 1.1 Windows Introduction Microsoft Windows is a series of graphical interface operating systems developed, traded and sold by Microsoft. Microsoft introduced an operating environment named windows as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUI).
Abstract This paper covers how Domain Management has evolved from Window NT 4.0 to Active Directory. Also it provides an in-depth look at all of the advantages Active Directory has over Window NT 4.0. The benefits of using Active Directory are broken up into Categories including the improvements in scalability, organization, and replication. This paper also shows how users are managed in an Active Directory environment as opposed to local users. Active Directory is a very useful tool created by Microsoft to make the server/client relationship easier to create and maintain throughout Windows based systems.
