Application Service Provider Vs Software As A Service (ASP Vs SAAS)


The traditional Application Service Provider – ASP Model is overrun by the upcoming Software as a service SaaS Model. Whether it is a deployment, upgrade or maintenence project – the onshore offshore model present in leading indian software companies were growing with a lot of money inflow as a result of ASP model. But In the present scenario, the companies like salesforce, workday are providing the software on demand services with client specific customizations based on the SAAS model also. In SaaS the customer pays for the services offered by the company/vendor and the cost involved in maintaining the application in their inhouse is not necessary.
Eventhough there is a cost reduction for customers who go for software as a service model, the rise of open source components that are available in the market makes this tough. And moreover for customers who require a lot of customizations, the ASP model is still leading the chart.
Whatever the changes are,.. It seems that in the near future the world leaders in software industry will be the ones who are operating based on the demands,..based on the software as a service model.

Rise of Data Transformation Services – DTS Packages

Interoperability and communication between applications plays a vital role in today’s emerging business needs.One such component which helps the business to transfer data between different system is the Data Transformation Service Packages famously known as DTS packages.This pasage will cover the differences between SQL Server 2000 and SQL Server 2005 with respect to the DTS Packages.Enterprise Manager of the Microsoft SQL Server 2000 provides an inbuilt menu within its IDE and the dts packages are accessed using the SQL Server 2000 DTS Designer IDE.
The DTS Designer 2000 allows us to perform the following tasks over a package such as 1. Designing 2. Executing and 3.Scheduling.
In SQL Server 2005, the DTS packages cannot be accessed the same way as we use to access it in SQL Server 2000. The reason being the advent of Microsoft SQL Server Integeration Services (SSIS) in the 2005 version. The two main IDE of the SQL Server 2005 are
Unlike the DTS Designer 2000 that was used to access the DTS Packages, the SQL Server Business Intelligence Development Studio supports the packages with its SSIS. Microsoft also provides a backward compatibility method of accessing the DTS Packages that were created in SQL Server 2000. Even after the migration of the database from SQL Server 2000 to SQL Server 2005, the DTS Packages which were originally created in the SQL Server 2000 environment can also be migrated to the 2005 Server. Since the DTS Packages are Server specific, by 1. opening the SQL Server 2000 Enterprise Manager and by 2. accessing the SQL Server Management Studio, the DTS Packages can be opened by DTS Designer 2000 through the SQL Server 2005 environment.
