The SAP Business One Service Layer is an extension on the Microsoft SQL Server that allows businesses to work with SAP Business One data management based on HTML and ODATA protocols. SAP Business One version 10 introduced the Service Layer to enable the exposure of more objects, fields, and functions when handling data. This allows developers to use any programming language, such as ASP, JAVA, or PHP.
The SAP Business One Service Layer offers a high level of scalability and provides more options for your database, but it involves a lot of data. You may need to move that data into other mission-critical business applications. That’s where things can get complicated.
