Different Between Microsoft Access and Microsoft SQL Server

Microsoft Access is a relational database management system (RDBMS) that is packaged with the Microsoft office to run under the Microsoft Windows operating system. Microsoft Access Database is a Visual Basic based application that permits SQL statements to be included in associated macros and VB scripts. Access Databases includes a Jet database engine, joint with a graphical interface, to offer easiness of use in building front-end database applications. Microsoft Access Software is a structured environment, used by beginner programmers, with little or no experience, to handle relatively small database functions. It is also a useful tool, for advanced developers, to supply rapid application development.

Access databases do not scale well for big databases or multiple-access, network environments. The underlying Jet Database is a file-sharing database that performs all processing at the client level. Microsoft Access is not designed for high volume multi-user environments that allow multiple clients to read, write and execute other operations on shared files at the same time.

Microsoft SQL Server is a server level RDBMS that incorporates the industry standard, SQL Server originated from the enterprise level, Sybase SQL Server, developed for mainframe operating systems, such as Unix and VAX VMS. The client-server interaction of SQL Server is more robust than Microsoft Access databases and is capable to handle high volume multi-user environments. SQL Server is one of Microsoft’s BackOffice servers, designed to handle client/server applications using the industry standard and ANSI compliant SQL. SQL Server is scalable for multiprocessing. It has the ability to reliably perform database functions and data warehousing. SQL Server can be configured to effectively and efficiently accommodate multiple users, 24 X 7, and is ideal for complex and demanding applications such as Web hosting, e-commerce, real time transactions and messaging systems.

The client-server configuration allows for the manipulation of large, multiple databases along with the capability to perform multiple and continuous data warehousing functions. It’s uptime and reliability reduces the chance of database corruptions, due to failed read and write operations, as well as data access conflicts. Microsoft SQL Server is, often at times, confused with MySQL. MySQL is also a server level SQL-based RDBMS which is developed by a Swedish firm and it is distributed freely under general public license.

In this hosting plan, you get as much similar benefits of having a dedicated server while being less expensive than dedicated server. In general, as VPS use the technique of partitioning the physical server into several (virtual) servers, all having independent operating systems.

 

 

Web site owners who are looking for great aspects associated with better control over the management website. Only VPS hosting is most measures than any other type of web hosting because of its security it provides. Root server access is the main advantage of dedicated hosting though shared hosting can be cheap and dedicated can be costly.

Various Server Side Technologies for Web Design

Web technology is based on the client/ server model. The client computer runs a web browser to see the web page. The software sends the request by the internet to the software program, which acts as the web server, running on the server computer. This responds and the web page is sent back to the browser. The web server software which runs on the server computer has many helpers to perform the tasks, which are the server side technologies for advanced web design. The tasks performed by the client side server, are all client server technology for advanced web design.

If a file has server side script then, the script inside the HTML file is performed by the server before the file is returned to the browser as plain HTML It works in many ways:

1.    A web page can be dynamically changed, edited or any content added to it.
2.    It can respond to any question or any data that is submitted from the HTML forms.
3.    It can access any data or database. This results obtained can be returned to the browser.
4.    The webpage can be customized to make it more useful for each user.
5.    The server side technology can provide security. This is necessary as the server code cannot be seen by a browser.

Some of the ‘server side scripting’ languages are:

1.    ASP/ASP.NET (.asp/.aspx) – ASP or Active Server Pages was developed by Microsoft for making advanced web pages in a web application framework. It helps in building dynamic website, web applications and web services. The most common language is VBScript.
2.    PHP(.php) – PHP:Hypertext Preprocessor is easy to learn. There are many readymade scripts available. It also helps in producing dynamic web pages and is a general purpose scripting language. It runs on the web server and has to be configured to process PHP code and create web content. It is free of charge. Most web servers and operating systems and platforms can display it.
3.    JAVA via Java server pages (.jsp) – This is a very popular web server side technology.  In this, the server tags are mixed with html. This is hard to learn and complicated. It has good programming techniques.
4.    ColdFusion Markup Language (cfm.) – This is from Macromedia and this server is not free. However, you can install a free ‘developer edition’. This can be used for developing and testing your applications. It is easy to learn as it consists of xml/html like tags. It is best used for web applications that are not too complicated.
5.    Perl (.pl) – It is also widely used. It is a powerful and advanced scripting language. This is mainly available in many cheap web hosting packages.
6.    Python (.py) – It is also easy to learn, but is not as widely used as PHP, ASP or even Perl. The disadvantage with this scripting is that it does not have a standard web application framework.

Besides these you also have Lasso(.lasso), Ruby (.rb) and SMX (.smx). There are all these server side scripts to choose from.

The most widely used server side script on Unix/Linux platform is PHP. It is not only easy to learn, but also fast to program. The Java/JSP/Servelets is the preferred choice for all the bigger projects. An expert Windows programmer will use ASP. Each one right from ColdFusion, Perl and Python are good, each having their own unique specialty.

It would be best for a beginner to learn one server scripting language first. With the experience gained, he can then go on to learning the other ones, as it will be easier.

UNIX Hosting 101

UNIX hosting involves a machine configured on a UNIX platform which is a multi-user computer operating system designed primarily for servers and advanced users. UNIX provides the base operating system architecture for many open source companies, such as Solaris (Sun Microsystems), Linux (GNU), and others. In regards to web hosting, choosing the UNIX web hosting alternative has its advantages and disadvantages.

UNIX has been around for years and it was the language of choice for midframe computer users. Windows actually copied the UNIX file naming convention technique when they created Microsoft Windows.

UNIX hosting is cheaper than Windows hosting. Because most web hosts use the free version of UNIX (like Linux), they don’t have to compensate for huge overhead expenses which you have with any Windows Operating System. Savings is passed to customers. In addition, those who use UNIX hosting usually get free tools and applications that have been written primarily for the UNIX community. Since UNIX hosting is an “open system”, its source code is publicly available for free from various web sites.

This allows web developers working for various companies and for different purposes to add rapid development of applications quickly. As a result, improvements come fast and problems are quickly resolved.

The main disadvantage of using UNIX hosting is that your provider may only allow access to your account via Telnet or SSH. As are result, you must have a strong working knowledge of UNIX commands in order to customize to your requirements. You may find yourself spending a lot of time learning the basics before you can enjoy the free advantages of UNIX hosting but learning the UNIX language is not that hard at all.

When considering the UNIX operating system and UNIX hosting, you need to consider your own technical abilities. Then take a look at the special features offered by each system and hosting company in light of the available technology and — sometimes more importantly — your budget.
