Universal database access layer to facilitate query
M. Mehedi Hasnat Al Amin, Rashedur Mohammad Rahman · 2014
Universal Database Access Layer (UDAL) is a JDBC based database access layer and every SQL supported database can be accessed through UDAL. Interaction with UDAL is simple as no one needs to know database specific SQLs to support multiple databases for products. This is due to UDAL which takes XML (Extended Markup Language) and JSON (JavaScript Object Notation) as input and returns corresponding response. XML and JSON both are standard and popular message format and simple which can support four most used DML operations at the moment which are Insert, Update, Select and Delete. All these types of DML operations are performed with huge data to measure the performance which can be increased by deploying the UDAL on the Cloud. If UDAL can be deployed as Web Service, everyone will be able to access it to eliminate the tight integration with product.
