Motivation for Building a Business Logic Layer Using PL/SQLBuilding a business logic layer using PL/SQL is very important and every organization or business should be motivated by the benefits of doing so since they outdo the cost of implementing business logic layer using PL/SQL. For instance, less time is consumed when entering data since the information is coded and coding he or she does not have to determine the code for every item that is being entered (Scott, 45). In addition, it would prevent errors such as selling a product twice which is a common error in the tourism industry.

There are occasions where a company sells a room and ends up reselling it due to poor business logic layers where products are not clearly defined. This leads to frustration on the part of the customer and such inconveniencies can make the company loss a lot of customers (Scott, 53). The use of PL/SQL in creating a complete business logic layer will ensure that multimedia data storage into the database is properly done. This would include the storage of photos, sight descriptions and maps.

Since PL/SQL would ensure efficiency in doing this, every business should seek to implement it (Scott, 34). Large scale businesses are likely to adopt this while the small scale businesses are likely to be left behind. However, they are all important in the economic development of any country and should be assisted to prevent them from being left aside from the mainstream. This is the role of the government and the large scale businesses. Graphical presentation are easily enhanced when business logic layer is implemented using PL/SQL.

This will attract more customers and result to increased profit margins. The business logic layer can be designed in such a way that it addresses different challenges such as difference in language and currency. This is made possible by the use of codes. Europe experiences such problems but the tourism industry can be sustained by building the business logic layer usinf PL/SQL. The solution is simple, universal and easily manageable. The solution does not involve storing Multilanguage translations in any form of files. Instead, the translations are stored in the database.

The customer is in a position to access the information in his or her preferred language (Kevin, 56). If one wants to include a new language to the existing application, he/she would only be required to add to the translation table new translations. These are examples of translation tables.

The other benefit of a business logic layer is that a file system is not needed since all information and business logic is stored in the database in the form of PL/SQL.

The procedures are grouped in packages making accessibility and modification easier. Implementing this package will definitely be a motivation since companies do not have to worry about the technological problems that are involved with application of new technologies and would result to the transition of any country into a networked economy when applied appropriately. The system is also easily expandable, compact and open. The well defined SQL/PL procedures make it modular and flexible thus enabling implementation of new features and upgrading of the system is easy.
