SAP S 4 HANA is the primary data store architecture of SAP AG based on the Java platform and uses the data interchange language (DML) to access data from any source. It is an extremely useful mechanism that allows programmers to work with information at a lower level, since it operates over a network. HANA is built on top of the database server, so the ability to use the data interchange language freely is not only provided by the Java platform, but also by the server application. The SAP Hana migrations are developed using the source code of JAVA, so they are easy to use and extend, as well as being safe against security issues like server attacks. They are written in Java and C++ and integrate well with JAVA and other developing tools.
The data is safely and easily migrate from one server to another, without requiring any changes to the application itself. For example, if a developer wants to have his own application that can be used on the desktop, laptop, or tablet computers, he can create a separate program for each target machine and then share the same data repository. Similarly, he can also have separate programs for mobile devices and different versions of the same data repository on each of the devices. Since HANA is designed to run on multiple targets, the programmer can also have access to different versions of the same data repository across multiple servers. These are some of the benefits of HANA.
HANA is designed in such a way that it is easy to start the process from scratch, by creating a new data source. There are several options in this section. The developers can select from the existing schemas. They can also create their own schemas, if they want to. For the process to be successful, it must ensure that there are no complications in database access, and that the data types are consistent.
The use of SQL scripts is a common option used in the s4hana migration. The use of this method is also supported by the rest of the SAP products, and thus, one need not worry about compatibility issues with the other products. The process however, needs to be carefully monitored so as to avoid problems during the migration. Migrations to HANA can take months or even years, depending upon the complexity of the task.
