DATABASE DEVELOPMENT & DESIGN
Cybermight LLC is a full service Online Database Design & Development company in Las Vegas. We provide database services ranging from simple to complex like conversion of DB2 to Oracle or MS-SQL, more complicated ones are Legacy applications to Client server architecture. MySQL now is the most common Database for Web Developments.

Because a business' processes are constantly changing, a database needs to be designed with expandability in mind. The requirement for both speed and expandability forms a crux of what database design is all about.

Detailed help, manuals, descriptions, corporate documentation, ideas and reviews, as well as press-releases, useful web-links, - you will find everything you may need.

We provide database services ranging from simple to complex like conversion of DB2 to Oracle or MS SQL, more complicated ones are Legacy applications to Client server architecture.

We are one of the luckier Database Programming companies since we had an opportunity to see large demand for our database services quickly evolutional from simple to complex.

Most organizations find their data becomes duplicated across different applications which have their own databases. Often databases are on different platforms with different database schemas involving databases on the web. Integrating many data sources can be a daunting task with many hidden costs.

PHP is a scripting language used to add executable content to Web pages. This course covers the fundamentals of programming in PHP and Web-related issues such as linking a series of forms together into a session, maintaining state if multiple users are on your site at the same time, cookies, security and other matters. We also cover PHP's interfacing to relational databases in some depth, with a particular study of MySQL.

PHP PROGRAMMING
Cybermight focuses on web development and application scripting using PHP.

PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into your Web site.

We can undertake the installation and custom modification of popular open source products such a os-commerce, phpbb forums, and many more.

We create interactive database driven modern web sites. Why we prefer to code in PHP than ASP.

In today’s computing environment PHP is considered overall economical to implement than ASP. The Open Source tag helps and provides great value to everybody. A lot of components are available free to download thereby eliminating the need to pay for licenses and continuous upgrades.

There are already several applications written in PHP and are available free to download that reduces overall project duration substantially. PHP is highly versatile so we can easily customize it to suit our requirement.

Technically PHP is considered faster than ASP because of incorporation of a parsing engine and the HTTP GET and POST variables are created automatically by PHP as global variables, unlike as in ASP where each compiler runs its own processes.

PHP is platform independent so it can perform well on both Linux and Windows operating system, allowing you to easily shift between servers while or after uploading the application.


COMMON INFO
CGI
or Common Gateway Interface is a means for providing server-side services over the web by dynamically producing HTML documents, other kinds of documents, or performing other computations in response to communication from the user. In this assignment, students who want to interface with the Oracle database using Oracle's Pro*C precompiled language will be using CGI.

Java Servlets
are the Java solution for providing web-based services. They provide a very similar interface for interacting with client queries and providing server responses. As such, discussion of much of the input and output in terms of HTML will overlap. Students who plan to interface with Oracle using JDBC will be working with Java Servlets.

Both CGI and Java Servlets
interact with the user through HTML forms. CGI programs reside in a special directory, or in our case, a special computer on the network (cgi-courses.stanford.edu), and provide service through a regular web server. Java Servlets are separate network object altogether, and you'll have to run a special Servlet program on a specific port on a Unix machine.

Java Output
Let's look back at our Java code example. You'll see a number of differences between the Servlet code and the CGI approach. Output is all handled by the HttpServletResponse object, which allows you to set the content type through the setContentType method. Instead of printing the HTTP header yourself, you tell the HttpServletResponse object that you want the content type to be "text/html" explicitly.

HTML
is returned to the user through a PrintWriter object, that is retrieved from the response object using the getWriter method. HTML code is then returned line by line using the println method.

Assuming that you all have a basic background in Java, so we won't provide a detailed treatment of exceptions here, but do note that IOException and ServletException both must either be handled or thrown.
At the Microsoft Professional Developer's Conference in March 1996, Microsoft hailed a new era of software development that will concentrate on intranets, the Web, ActiveX, HTML, applets, browsers, and Java. Microsoft emphasized the integration of tool sets for the various versions of Windows and Internet/intranet application development. It also revealed a unified shell and browser that may become a universal client.

ODBC and JDBC
Multidatabase APIs have gained favor with developers working with SQL databases. Microsoft's ODBC and JavaSoft's JDBC let you use one API to write programs that operate on various SQL databases. Java developers can also use Microsoft data access APIs where the target execution environment is 32-bit Windows. Presently, ODBC or JDBC is the best choice for developing multiplatform programs. Let's examine ODBC and JDBC to see what that choice involves.

ODBC is the most widely used call-level interface for accessing SQL databases. JDBC is a new API that provides an object layer that works with ODBC drivers to abstract SQL programming for Java developers.

The ODBC and JDBC architectures include loadable database drivers and a driver manager. Database drivers are conceptually similar to printer drivers because database drivers let you expand a program's functionality without rewriting its source code. The database drivers are libraries that the driver manager invokes when your program connects to an ODBC or JDBC data source. Your program can use drivers that work with a specific database management system (DBMS), such as Oracle, or drivers that connect to ODBC and JDBC servers. Although these servers can connect to multiple data sources, clients use only one driver to connect to the server. This server-based architecture produces a thinner client by replacing multiple drivers, client libraries, and protocol stacks with one driver and network transport. When your code uses ODBC or JDBC, a driver manager validates the arguments in your call and loads the appropriate driver for the data source to which you are connecting. The UNIX and Macintosh versions use shared libraries for the driver manager and drivers, whereas NT, other Windows versions, and OS/2 use DLLs.

Dozens of ODBC drivers already exist, so INTERSOLV developed bridge software for JavaSoft to let JDBC applications use ODBC drivers. Figure 1 illustrates the JDBC architecture that includes drivers, a driver manager, and a bridge for accessing ODBC data sources.

All ODBC and JDBC data access uses SQL queries to define and manipulate database tables. ODBC and JDBC drivers understand the same SQL (ANSI SQL with X/Open escape clauses) and models for query preparation and execution.

THE BASICS OF JAVA
Java is well known for creating Web applets that you download with HTML pages, but you can also use it to program applications, including SQL applications. Java programs are of two types. Java applets are components embedded in Web pages that a browser executes. Java applications are main programs that the Java interpreter, the Java virtual machine, executes. Java supports a distributed, client/server computing model, and today's Web-orientation exemplifies this model. Applets run as clients and conform to strict client security rules. Applications usually execute at a server, but they can run anywhere a Java virtual machine exists. In a typical scenario, a Windows NT server can support PC, Macintosh, OS/2, and other clients. To embed an applet in an HTML document, you specify an <APPLET> tag, but other scenarios will soon appear. Microsoft applications will soon use applets in a way that is similar to how they use Visual Basic custom controls (VBXs), Object Linking and Embedding custom controls (OCXs), and ActiveX controls.
