Abstract
System, and program product for rebasing an application. The application is analyzed to identify the database components that require remapping to a new database. These components are remapped to utilize the new database and/or a new interface layer that utilizes the new database. The components can be remapped by rewriting the component and/or redirecting the component. However, the configuration that is used for the data in memory is maintained, thereby reducing the number of components in the application that require modification.
Claims5
A system for rebasing an application, the system comprising:
- an analysis system for identifying an interface layer of the application that manages application data using a memory configuration of the application data, and for identifying an interface database component in the interface layer that allows management of at least some of the application data in a first database that stores the application data;
- wherein the analysis system further analyzes a services layer;
- a database schema system for defining a second database based on requirements of the analyzed services layer;
- wherein the second database stores at least some of the application data;
- defining the second database based on the schema for the second database;
- a remapping system for remapping the database component to allow management of at least some of the application data in the second database, wherein the remapping comprises rewriting the interface database component or redirecting the interface database component to use the second database, wherein the memory configuration of the application data is maintained;
- and
- an interface system for adding a second interface layer that allows management of at least some of the application data in the second database, wherein the remapping system further remaps another database component to allow management of at least some of the application data in the second interface layer.
A program product stored on a recordable medium for rebasing an application, which when executed comprises:
- program code for identifying a first interface layer of the application that manages application data using a memory configuration of the application data, and for identifying an interface database component in the first interface layer that allows management of at least some of the application data in a first database that stores the application data;
- program code for identifying a services layer of the application that implements services of the application;
- program code for analyzing the services layer;
- program code for defining a schema for a second database based on requirements of the analyzed services layer;
- wherein the second database stores at least some of the application data;
- program code for defining the second database based on the schema for the second database;
- program code for adding a second interface layer that allows management of at least some of the application data in the second database;
- and
- program code for remapping the interface database component to allow management of at least some of the application data in the second database, wherein the remapping comprises rewriting the interface database component or redirecting the interface database component to use the second database wherein the memory configuration of the application data is maintained.
