14. The system of claim 13 wherein said at least one indicator provides an indication that said WAPM is engaged in an error test with said WPIM.
15. The system of claim 13 wherein said at least one indicator provides an indication that said WAPM has successfully linked with said WPIM.
16. The system of claim 13 wherein said at least one indicator provides an indication that said WAPM has not received communication from said WPIM within a specified time interval.
17. An RF access control system for controlling access to an access point, the control system including:
an access control panel operable to make access decisions for the access point;
a wireless panel interface module (WPIM) in communication with the access control panel and including a transceiver operable to send and receive access signals;
a Wireless Access Point Module (WAPM) fixedly positioned adjacent the access point and in communication with the wireless panel interface module, said WAPM having installed software, said WAPM providing an indication to an observer of the version of software installed on said WAPM using said at least one indicator; and
a card reader, said card reader providing data to said WAPM, wherein said at least one indicator provides an indication that said WAPM has received data from a card reader.
18. The system of claim 17 wherein said at least one indicator provides an indication that said WAPM does not understand data received from said card reader.
19. The system of claim 17 wherein said at least one indicator provides an indication that access through the WAPM has been granted in response to said data from said card reader.
20. The system of claim 17 wherein said at least one indicator provides an indication that access through the WAPM has been denied in response to said data from said card reader.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of determining a data dictionary for data dictionary compression, the method comprising:
receiving, by a processor, statistical information about a data set included in a column of a data table;
receiving, by the processor, additional information about the data set that indicates one or both of a data format utilized by the data set and a type of information represented by the data set; and
generating, by the processor, a data dictionary for compression of the data set based, at least in part, on the statistical information and the additional information, wherein the data dictionary is generated such that the data dictionary is capable of compressing data that is statistically predicted to be received at a future point.
2. The method of claim 1, the method further comprising:
analyzing, by the processor, retrieved data from one or more sources to provide information about one or more aspects of the data set, wherein the retrieved data includes one or more of: metadata, database statistics, data profiling, and user input; and
generating, by the processor, at least a portion of the additional information based, at least in part, on a result of that analysis.
3. The method of claim 1, wherein the additional information about the data set includes at least one of: data constraints, declared data types, inferred data types, expressions included in the data set, patterns identified in the data set, monotony of values in the data set, variability of values in the data set, value ranges in the data set, excluded value ranges in the data set, and growth range of values in the data set.
4. The method of claim 1, wherein the data dictionary is configured to support both data compression and one or more of: arithmetic operations, order preservation, and fixed length encoding.
5. The method of claim 1, the method further comprising:
predicting, by the processor, one or both of a type of data and a quantity of that data that will be received at a later time; and
modifying, by the processor, the data dictionary such that the data dictionary is configured to accommodate one or both of the type of data and the quantity of that data that is predicted to be received.
6. The method of claim 1, the method further comprising:
determining, by the processor, a number of values included in the data set;
determining, by the processor, whether the number at least meets a threshold that indicates a minimum quantity of values needed to build the data dictionary; and
responsive to a determination that the number is below the threshold, building, by the processor, the data dictionary based, at least in part, on a number of common suffixes that are included in the data set.
7. The method of claim 1, the method further comprising:
compressing, by the processor, the data set based, at least in part, on the data dictionary, wherein the data dictionary is a columnar dictionary that is configured to reduce encoding and decoding costs of the data set by exploiting metadata about data that is included in a column that is compressed.
