摘要:
A computer-implemented method of providing low-latency responses to queries using a distributed storage system comprising a plurality of distributed nodes is disclosed. The method comprises generating a plurality of database views, including a database view joining first digital data and second digital data, the first digital data being stored in a first digital data repository of the distributed storage system using a first storage format, the second digital data being stored in a second digital data repository using a second storage format different from the first storage format; storing the plurality of database views in a third digital data repository using a column-oriented storage format; storing metadata for the plurality of database views, including schema information for the database views and location information of one or more distributed nodes storing data corresponding to the database views; loading the metadata into a search system configured to receive a search query and return a result set for the search query based the metadata.

A method for providing low-latency responses to queries to a data search system comprises storing first digital data in a first digital data repository using a first column-oriented storage format; storing second digital data in a second digital data repository using a second column-oriented storage format, wherein the second column-oriented storage format is different from the first column-oriented storage format; generating a plurality of pre-computed views based on both the exposure data and the risk item data; storing the plurality of pre-computed views in the second data repository using the second column-oriented storage format; and in response to receiving a search query, determining a result set that is responsive to the query based on one or more particular pre-computed views of the plurality of pre-computed views and providing the result set to another computer or display device as output.

In an embodiment, a method comprises generating and storing metadata that maps a domain model to data stored in a data store, wherein the domain model describes the data and relationships between the data; receiving, from a client application, a request for data stored in the data store, wherein the request is in a first query language; translating the request into one or more queries based on the metadata, wherein the one or more queries are in a second query language; sending the one or more queries to the data store; receiving a first result set from the data store, based on the data store executing the one or more queries.
摘要:
A computing system and platform uses various types of data stores to allow efficient querying of, and accelerated access to, extremely large data sets. One such data store is a dimension store that combines key-value and columnar stores, access to which is provided by several selectable mechanisms chosen based the nature of the data of interest. These include bitmap-based access, us of an optimized columnar data format, and access via namespace identifiers. A compressed, optimized page data format is provided for storing and analyzing large fact-based data. The complex dimension store is used to provide complex relationships and interpretation of the fact-based data, enabling high-performance advanced queries, with bitmap indexes passed between the two stores. Dimension data is stored in an encrypted manner throughout the system, and can be exchanged among parties in a secure manner.
摘要:
A system and method are provided for identifying exposure concentrations. The process of determining exposure concentrations may include organizing exposure data, defining parameters, determining elevated exposure concentrations, and providing output results. The exposure data may relate to at least geographical locations, policies, accounts, portfolios, treaties, and other exposure data. The parameters may be defined to include at least an area of analysis, a region of interest, a threshold amount, results parameters, and other parameters. The exposure concentration may include at least defining and locating exposure locations using various techniques. The results may be presented using textual, graphical, or other display schemes. The output may be configured to convey information such as positional accuracy of an identified area, exposure accumulation in a defined area, and other information.
摘要:
A method of simplifying a digital map for display is disclosed. The method comprises receiving a digital map for a geographical region, the digital map being organized into a plurality of raw map tiles associated with a plurality of sub-regions of the geographical region; retrieving configuration data related to visibility to humans for simplifying the digital map; identifying one or more features from each of the plurality of raw map tiles, each feature corresponding to a cluster of pixels, at least two features corresponding to a common pixel; generating a specific modified map tile for a particular raw map tile based on the configuration data by assigning a maximum of all values of pixels of certain features associated with the particular raw map tile that correspond to one or more common pixels to at least one pixel of the one or more common pixels not already having the maximum as a value.
摘要:
A system automatically processes rules for allocation of resources to mitigate damages resulting from a catastrophic event. Overlapping interests of various stakeholders are processed in a deterministic manner to ensure repeatable processing and modeling. In one embodiment the resources are disaster aid items; in another they are obligations regarding insurance.
摘要:
A risk exposure model is developed for network or moveable assets not specific to a single, fixed address or location. An asset map using a plurality of geographic representation points is used to identify the physical locations of the asset portions (or possible physical locations in the case of a moveable asset). Baseline geographic, geologic, political, and demographic data is similarly represented using geographic representation points. Meta-data associated with each geographic representation point is used to identify details related to the asset or baseline feature at that geographic location. Risk exposure values are then calculated using the geographic representation points specific to the asset portions that are subject to risks associated with the location of the asset portion.
摘要:
A system stochastically models events related to potential perils (e.g., hurricanes, terrorist attacks) using a weighted period event table. Both rare and likely events are captured in modeling with minimal computational overhead, allowing appropriate allocation of resources. Applications include disaster response, municipal planning, financial risk modeling and allocation.
