ASP or PHP which is better?

ASP runs only in windows ( can also run on Linux but not supported by many host and not so compatible), while php runs on both Linux and windows server. So its clear that ASP is most expensive to run coz we need window server and then iis .. even though iis is free but window server cost much more. Database:ASP supports all databases but its best run with access and ms sql. If your application requires more users and more constant hit then ASP is better coz you can use mssql which is far better than mysql. But if you have fewer users then you can also use access with asp but the main problem with access is, it cant handle more concurrent hits and crashes most of the time. ASP doesn’t runs well with mysql, you may get problems on paging . PHP runs best with mysql, and also support mssql. Best part of mysql with php is its more versatile and easy in compare to asp with mssql. MYsql is simple and easy to use while mssql is more complex. If your database size is less than 2GB then you must use mysql with PHP but if you have high size database then mssql is the option. The main draw back of asp code on database is, when you create record set asp will load all the data to the record set . So no matter you are showing few records , yours recordset is holding lots of data and if you have 10000's of records your asp application may hang. So you must use Store Procedure with mssql or view with access. But in PHP you dont have that problem. Programming comfortable: If you know both asp and php language programming is easy on both side. PHP is more c/c++ style programming but that doesn’t mean that you have to program is oops way. ASP is more VB style programming. As per the online resources is concern you will get php recourses more than asp. With php you can also easily work on server related programming like dns, meta data e.t.c but in asp its very hard to work on server side manipulation and you need special permission to do that from admin. Many Window server provider dont give you advance access that you need to work for asp program like folder permission, root parent path enable e.t.c while in php you can do it easy with ftp command. Business point of view: Mainly customers dont know what programming language , they need their program on. but many have cheap hosting with linux so they may ask you to make on php. Since there are many php programmer in comparison with asp one, you may have chance to get more work being asp programmer. But it just assumption. As per my experience making program on asp is more profitable than in asp as many programmer or business owner they get less asp programmer and for advance programming you can find your customer easily. while in php there are many php programmer so competition is high and even though demand is high, you chance of getting work is less... ( just a perception)Extra cost: Many add-ons for php are free ( if hosted on Linux). but with asp you need to pay for almost everything like mail component, ftp component, image upload component e.t.c Conclusion:By above idea we can say that PHP Programming is cheaper than ASP programming. but with database if you have complicated requirement i suggest ASP than php. As per the programming is concern, since resources of php are widely available than asp so its easy to program php than asp but as per the syntax and programming concern its of no difference.

Concept Of An Access Database

The invention of computer does not itself make it easy for human beings to work faster but it is the information stored in it is quite important than others. To store data and information in a computer database is used. A database is made to help store and manage all the information in a systematic way which in future could be retrieve easily for update. Database such as Microsoft Office Access 2007, helps you in processing information effectively for using various business needs. How an access database helps:1. It helps in adding and storing new data to an existing one.2. It enables the user to edit and delete the data.3. It helps in changing the location of an item and also removes the discarded item.4. With the help of this data can be organized and displayed in different views.5. You can also use these data with others by means of reports, intranet or internet.An access database has some basic components like tables, forms, reports, macros, modules and queries. The data is stored in rows and columns. Though tables are similar to spread sheets it could organize data in a more systematic manner than spread sheets do. The data entry screens or forms act as a user friendly interface that contains various commands and help control user interactions to work with the data. Macros in an access database are a simplified programming language which adds functionality to the database. These are also used to automate most database operations like opening a report, closing the database or running the query. Modules, which also help to add functions into the database, are written using the visual basic for applications programming language and are consists of declaration, statement and procedures.An access database helps in presenting data in a readable format like reports. The report which consists of current data can be viewed, printed and also export to others. To retrieve data from various tables and display it in a single datasheet queries are used. The other function of queries is to act as record source for forms and reports. However they can also be used to perform a task with data.The access database used different subject based tables to store data. In access 2007, data from multiple tables are linked and arranged in a logical manner by using primary key fields. A primary key which is a set of fields acts as a unique identifier for every row in a table. You must specify the unique identification number or the primary key fro a table. For example a students ID number could be used as a primary key in the students table. Operations such as searching, querying, and sorting can be speed up by using primary key of a table.Since data is stored in different tables, you can relate them by creating table relationships. The normalization rules applied to structure the tables to ensure information is divided in logical manner in various tables.
