Systems and methods for hosting variable schema data such as dynamic tables and columns in a fixed physical database schema. Standard objects, such as tables are provided for use by multiple tenants or organizations in a multi-tenant database system. Each organization may add or define custom fields for inclusion in a standard object. Custom fields for multiple tenants are stored in a single field within the object data structure, and this single field may contain different data types for each tenant. Indexing columns are also provided, wherein a tenant may designate a field for indexing. Data values for designated fields are copied to an index column, and each index column may include multiple data types. Each organization may also define custom objects including custom fields and indexing columns. Custom objects for multiple tenants are stored in a single custom object data structure. The primary key values for the single custom object table are globally unique, but also include an object-specific identifier which may be re-used among different entities.

Custom entities and fields in a multi-tenant database system

A system, method, and article of manufacture are provided for managing information in a development architecture framework. Common information that is used by a plurality of components of a system is allowed to be accessed in a single, shared repository. Unique information that is unique to the components of the system is stored in corresponding designated folders. Media content communicated in the system is managed based on metadata thereof.

Managing information in an integrated development architecture framework

In general, in one aspect, the invention relates to a method for transaction processing. The method includes specifying metadata and storing the metadata. An index is created in response to the stored metadata. The method also includes receiving a transaction, generating an index log of changes to the index in response to the received transaction, and modifying the first index in response to the generated index log.

Database system and methods

Disclosed is a method for creating a real-time search engine over the Internet which provides a search response containing data object descriptions and server descriptions of data objects that are currently available for transfer from a provider server directly to a recipient client in response to a recipient client search request The method comprises the provider server connecting to a Real-time search engine through the Internet, the provider server providing the Real-time search engine with data object descriptions of data objects residing on the provider server, and the Real-time search engine indexing data object descriptions associated with the data object of the provider server, wherein the data object descriptions provided by the provider server are purged from the Real-time search engine when the provider server is disconnected from the Real-time search engine

Real-time search engine

A method and system for producing graphics. A hierarchical structure of a database is determined. A visual table, comprising a plurality of panes, is constructed by providing a specification that is in a language based on the hierarchical structure of the database. In some cases, this language can include fields that are in the database schema. The database is queried to retrieve a set of tuples in accordance with the specification. A subset of the set of tuples is associated with a pane in the plurality of panes.

A method and system for accessing and sharing metadata amongst a number of data marts through the use of object referencing. A global repository is created. Shared folders containing metadata is contained in the global repository. Any number of data marts can be linked to the global repository. Stored within the folders of the linked data marts are references pointing to certain metadata stored in the shared folders of the global repository. Multiple data marts can reference the same metadata in the global repository. Thereby, the same metadata can be accessed, used, and shared by multiple users across different data marts, provided that they have been granted the proper authority. New metadata can be promoted from a linked data mart into the global repository so that it can be shared, and updates to shared metadata can be automatically propagated to all users referencing that metadata.

A method for updating a target table of a data mart in response to changes made by a transaction to data stored in a source table of an operational database. Data that was changed in the source table by the transaction is stored in a dynamic image table of a change capture database. Data that was not changed in the source table by the transaction, but which is nevertheless required to be mapped to the target table, is stored in a static image table of the change capture database. The change capture database also contains relevant information regarding the transaction. Once the dynamic and static image tables are properly staged, the changes are propagated from the change capture database to the target tables of the data marts. In other words, data is extracted from the change capture database and subsequently transformed and loaded, thereby minimizing the impact to the operational database. Thereupon, the tables of the change capture database are truncated to discard data which is now no longer needed.

A method and system thereof for performing real time transformations of dynamically increasing databases is described. A session, identified as a real time session, is initialized. The real time session repeatedly executes a persistent (e.g., continually running) data transport pipeline of the analytic application. The data transport pipeline extracts data from a changing database, transforms the data, and writes the transformed data to storage (e.g., a data warehouse or data mart). The data transport pipeline is executed at the end of each time interval in a plurality of contiguous time intervals occurring during the real time session. The data transport pipeline remains running after it is executed, until the real time session is completed. Accordingly, new data are transformed in a timely manner, and processing resources are not consumed by having to repeatedly re-establish (re-initialize) the data transport pipeline.
