SQL Server ToolsĪs just explained, SQL Server is a client/server DBMS, so to use SQL Server you need a client (an application that you use to interact with SQL Server), which you use to give it commands to be executed (in database parlance the term execute is used for run). The current version of The current version of Microsoft SQL Server is SQL Server 2016 (although prior versions are in use in many organizations). The client can be SQL Server–included tools, scripting languages, web application development languages, programming languages, and more. You can run a locally installed copy, or you can connect to a copy running on a remote server to which you have access. The server software is the SQL Server DBMS. Why is this significant? Because to work with SQL Server, you need access to both a computer running the SQL Server software and client software with which to issue commands to SQL Server: In fact, most networks are set up so that users have no access to the data, or even the drives on which it is stored. You never need to access the data files directly. The fact that data is stored elsewhere or that a database server is even performing all this processing for you is hidden. Regardless, the client software communicates with the server software for all database interaction, be it on the same machine or not.Īll this action occurs transparently to you, the user. The client and server software may be installed on two computers or on one computer. The server software processes the request filters, discards, and sorts data as necessary and sends the results back to your client software. If you request an alphabetical list of products, for example, the client software submits that request over the network to the server software. The client is the piece of software with which the user interacts. These requests or changes come from computers running client software. All requests for data, data additions and deletions, and data updates are funneled through the server software. Only the server software interacts with the data files. This software runs on a computer called the database server. The server portion is a piece of software that is responsible for all data access and manipulation. Client/server applications are split into two distinct parts. The former (which includes Microsoft Access) are designed for desktop use and are generally not intended for use on higher-end or more critical applications.ĭatabases such as SQL Server, Oracle, and MySQL are client/server–based databases. Client Server SoftwareĭBMSs fall into two categories: shared file–based and client/server. In addition, Microsoft SQL Server is a commercial product, and for those interested in no-cost open-source offerings, other DBMSs may be more attractive. So why not use Microsoft SQL Server? First and foremost, Microsoft SQL Server runs only on computer running a Microsoft Windows operating system, and if your computer runs another operating system (such as Linux), then obviously you’ll not be able to use Microsoft SQL Server. Simplicity-Microsoft SQL Server is one of the easiest DBMSs to install and get up and running, and includes administrative tools that make management of the server painless and simple.Integration-Microsoft SQL Server is tightly integrated with other Microsoft offerings as well as the Microsoft Azure cloud.Trusted-Microsoft SQL Server is used by some of the most important and prestigious organizations and sites, all of whom entrust it with their critical data.Performance- Microsoft SQL Server is fast (make that very fast).Why do so many organizations and developers use a Microsoft SQL Server? Here are some of the reasons: Microsoft SQL Server has been around for a long time and is in use at millions of installations worldwide. Microsoft SQL Server is a DBMS-that is, it is database software. It is the database software (DBMS or Database Management System) that actually does all the work of storing, retrieving, managing, and manipulating data in a database.
