Abstract: Systems and methods for providing a cost estimate for a data processing system are provided. An exemplary method may include selecting application programs from a set of application programs, wherein each application program may have a number of objects. The method may further include entering data descriptive of a load profile, retrieving a set of sizing coefficients for each object of the selected application programs, and estimating the hardware requirements for each one of the objects of the selected application programs by entering the sizing coefficients and the load profile into a sizing model. The method may further include entering the hardware requirements for each one of the objects of the selected application programs into a cost estimation component to provide a cost estimate for each one of the program objects of the selected application programs.

Abstract: Methods and apparatus, including computer program products, for processing data objects having data items. The method includes classifying each data object into a write-enabled object or a read-only object, storing write-enabled data objects in a database, and archiving read-only data objects. The archiving includes converting the data objects to markup objects, wherein each markup object represents the data items of the corresponding data object, concatenating the markup objects to a single data structure that is byte addressable, and indexing object identification for each markup object to addresses of the data structure.

Abstract: The invention allows multiple application systems to use a single database system. The database system is divided into at least a first memory portion and a second memory portion. The memory portions are disjunctive. The database system stores a first assignment of a first profile to the first memory portion and a second assignment of a second profile to the second memory portion . The first and second profiles are unique and refer to the first and second application systems, respectively. The first application system and the second application system access the first memory portion and the second memory portion, through the respective profiles.

Abstract: Multiple application systems use a single database system. At least a first application system (901) and a second application system (902) run application services for application system users. The database system (900) has at least a first memory portion (920-1) and a second memory portion (920-2). The memory portions are disjunctive. The database system (900) stores a first assignment of a first predetermined profile (110) to the first memory portion (920-1) and a second assignment of a second predetermined profile (111) to the second memory portion (920-2). The first and second profiles (110, 111) are unique and refer to the first and second application systems (901, 902), respectively. The first application system (901) and the second application system (902) access the first memory portion (920-1) and the second memory portion (920-2), through the respective profiles (110, 111).
