摘要:
Continual generation of index advice that includes generating an index advice for an index of a table in a computer database and recording values of statistical attributes of the index advice accumulated across repeated generations of the index advice. The generating and recording typically are carried out continually without user intervention. Embodiments include recording values of attributes of the index advice that specify an index. Typical embodiments also include, continually and without user intervention, recording values of attributes of the index advice that characterize usefulness of an index and recording values of attributes of the index advice that characterize cost of creating an index.

A database management system maintains a record of queries which can be executed against the database. For a given auxiliary database structure, an advisory function automatically reviews the query record and identifies those queries which might execute with greater efficiency using the auxiliary database structure, presenting analytical information to the user. Preferably, the auxiliary database structure is an index, and the information is used for determining whether to include the index in the database definition. Preferably, a query optimizer records potentially useful indexes when considering multiple alternative database optimizations, and this information is later retrieved to identify queries which would benefit from an index.

In response to a request to access a database, a decision is made that a secondary data structure associated with the database needs rebuilding. A reason why the secondary data structure needs rebuilding is determined and the reason is presented via a user interface. In various embodiments, other information may also be presented, such as an identification of the operation associated with the request that encountered the secondary data structure and an identification of a most recent query that used the secondary data structure. In this way, the user may be informed of the reason why a secondary data structure needs rebuilding, so that the user may opt to take action to prevent secondary data structures from needing rebuilding in the future, and thus avoid the expense and time of rebuilding the secondary data structures.
摘要:
A method and system for tracking and verifying estimates, invoices, and billing exceptions for charges billed to a customer by a vendor is disclosed. The vendor submits an estimate via a billing verification system. The system generates an estimate record and facilitates customer review of the estimate. The system also receives an invoice for the completed repair from the vendor and generates an invoice record. Based on the estimate record and the invoice record, the system can perform an audit to compare the invoice to the estimate. The system also enables the customer to review the invoice via the billing verification system to identify billing exceptions associated with any disputed charges. A billing exception record is generated in the billing verification system for each of the billing exceptions. The vendor is then notified of the billing exceptions. The vendor reviews and responds to the billing exception records via the billing verification system. A billing exception response record is generated for each vendor response. The customer is then notified of the reviewed billing exception response records.
摘要:
The present invention provides a method of identifying one or more epigenetic markers associated with psychosis-associated diseases such as bipolar disease or schizophrenia, the method comprising a) obtaining a first group of samples comprising genomic DNA from a plurality of bipolar or schizophrenic subjects and a second group of samples comprising genomic DNA from a plurality of control subjects; b) performing DNA methylation analysis to determine methylation differences in one or more DNA regions between the first group and second group of samples, wherein a methylation difference in a DNA region is indicative of an epigenetic marker associated with bipolar disease or schizophrenia. The invention also provides one or more epigenetic markers associated with psychosis-associated diseases such as bipolar disease or schizophrenia.
