In an example embodiment, a request for data is received from an end-user device, the request including one or more contextual attributes of the end-user device. The request is forwarded to a data provider. Data is then received from the data provider. It is determined if the data includes tagged sensitive data. If so, then the tagged sensitive data and the one or more contextual attributes are sent to a data access platform. Then policy constraints corresponding to the data are received from the data access platform. The sensitive data is encrypted in a manner that a data privacy module on the end-user device only decrypts the sensitive data when one or more contextual attributes of the end-user device meet one or more requirements identified in the policy constraints, and then the encrypted sensitive data and the policy are sent to the data privacy module.

Private data access controls in mobile applications

A system, method, and computer program product are provided for executing a notification query derived from a download cursor for a business object to identify an updated subscription. The download cursor is run against the updated subscription to generate result rows. The result rows are sent to a client device in an import message. Additional systems, methods, and computer program products are provided for guaranteeing at-least-once delivery of a message.

Message based synchronization for mobile business objects

A system, method, and computer program product are provided for invoking an operation to change a current data row of a table in a local database. As a result, a pending change data row is inserted in the table, distinguished by a primary key comprising a common key value and a pending change indicator. The pending change is then submitted for synchronization.

Pending state management for mobile business objects

Systems, methods and computer program products for inherently integrating mobility with an enterprise are described herein. Enterprise data is accessed from one or more data sources, wherein such data sources may comprise structured and unstructured data sources. The data is transferred from the enterprise to a plurality of mobile devices over a plurality of diverse networks. In an embodiment, such transfer takes into consideration characteristics of the diverse networks. The enterprise receives data generated by mobile devices while performing enterprise-related operations at the wireless edge. The enterprise responds to environmental changes using the received data.

Unwired enterprise platform

Systems, methods, and computer program products are provided for ensuring coherency between user data in a client and their corresponding state in enterprise information systems (EIS) wherein data migrates and subscriptions change over time. A mobile business object (MBO) identifies an update to a subscription or a change in set membership in order to provide updates to a client device and EIS systems. Cached data is filtered for client device users who synchronize data they are interested in (i.e., subscribed to). In an embodiment, the method keeps track of set membership by remembering on a per remote identifier/business object basis the set membership for a parent business object. When set membership changes, the method sends delete notifications to the device to remove ex-members. The method recognizes common relationship types in a business scenario and handles reference-type relationships as well as containment-type relationships. The methods include key tracking and membership tracking.

Membership tracking and data eviction in mobile middleware scenarios

A system, method, and computer program product for forming and transmitting a TCP/SMS message are presented. Steps for forming a TCP message, encoding the TCP message, and wrapping the TCP message in an SMS message are disclosed.

TCP over SMS

A system, method, and computer program product are provided for creating a data subscription to a remote database. Additionally, a system, method, and computer program product are provided for creating a persistent query, wherein a table in a remote database is represented by a meta-data definition.

Persistent query system for automatic on-demand data subscriptions from mobile devices

A method for cloning of prepared statements for execution against a database is described. In one embodiment, for example, a method for executing a database statement comprises steps of: preparing at least one template for execution of a statement against a database; storing the at least one template in a shared cache available to a plurality of database connections; in response to a request to execute a particular statement on a given database connection, determining whether a template for the particular statement is available in the shared cache; if the template is available in the shared cache, creating a database statement based on the template for execution on the given database connection; and executing the database statement on the given database connection.

Database system providing methodology for prepared statement cloning

A distributed (e.g., client/server) computing environment is described which implements protocol methodology simplifying the use of objects in distributed applications. In particular, the methodology facilitates streaming to clients executable objects (e.g., Java objects) stored and managed remotely (e.g., objects stored and managed in relational databases), so that the objects may be executed or otherwise manipulated locally at the clients. The methodology is implemented by extending an existing streaming protocol to support a &ldquo;chunked&rdquo; datatype; within a data stream, the system can have individual data items which are themselves streams of indeterminate length. This streaming data type is an undifferentiated data type or simply a &ldquo;BLOB&rdquo; (i.e., binary large object). Using the BLOB extension, the system provides a set of BLOB subtypes which take advantage of existing object streaming mechanism (e.g., Java streaming) but convey additional information in the form of self-describing metadata. The metadata contains all necessary information on the BLOB data for clients and servers to narrow the BLOB data itself to the appropriate subtype and extract the semantically correct values from it. In this manner, the system may employ the streaming protocol to receive requests and input objects and, in response thereof, generate and send output objects and output result sets with rows and columns that may include objects in them, or send back output stored procedure parameters that may be objects.
