ABSTRACT:
BACKGROUND
Computer programs generally maintain data in a variety of formats. There usually is one format that is unique, and typically proprietary, to each computer program in which raw data are stored persistently. This format usually is designed to reduce the amount of information actually stored and, in some cases, to restrict the ability of a third party to access the data. Data in this format generally are created by a “save” function of the computer program. The save function formats the raw data and stores the formatted raw data in yet another format, called a “file,” that is defined by the operating system for which the computer program is designed. Data that are being processed by a computer program are stored in another format, also typically proprietary, called a “data structure,” which generally is stored in volatile or working memory during execution of the computer program. A data structure usually is designed to permit the data to be processed efficiently by the computer program, while minimizing the amount of memory needed to represent the data.
With many computer programs, the most useful form of the data from the perspective of the user is its visual form, e.g., what is displayed on a computer display or what is printed. However, this form of the data often is not captured into permanent or persistent storage, unless it is printed and the printed form is electronically scanned. In particular, the file format used by a computer program often does not maintain data in a visual form for several reasons. The visual form of the data generally requires more information to be represented and can be reconstructed from raw data that require less information to be represented. Therefore the need to store the visual form of the data is generally considered unnecessary.
Part of the visual form of data produced by a computer program is generated, for example, from environmental data (such as the date and time) or user selected data that are being processed, and is not recoverable from the file format, but only from the data structures of the computer program. Although some data structures represent the visual form of the data, often there is no mechanism to retain the visual form of the data other than by printing. Some operating systems permit displayed data to be copied from one computer program to another using a “cut-and-paste” operation, but this operation generally requires the other computer program to be in operation on the same machine. Some computer programs also do not have these operations available to the user. For some computer programs, the printed form of the data, not the displayed data, is most useful and this operation does not provide access to the printed data.
Even if the visual form of data from a computer program were stored, as new versions of the computer program are used, or if the computer program is no longer available, access to that data is impeded. Also, another computer program still might not be able to access the data if the data are stored in a proprietary format.
This lack of access to the visual form of the data from a computer program creates a variety of problems when this form of the data is desired for creating compound documents from multiple sources of data, particularly if the data are created, used and shared over a period of time by multiple different users with multiple different computer programs that are dispersed geographically. As a particular example, in the pharmaceutical industry, data may be acquired from many laboratory instruments in geographically dispersed laboratories over a significant period of time, and then may be combined to produce reports, for example, for regulatory compliance. The inability to centrally access an electronic visual form of the data from these instruments adds a significant cost to regulatory compliance.
Electronically scanning printed documents to provide shared electronic access to such documents has several disadvantages. First, scanning consumes significant resources, including time and effort of personnel. Second, a significant time delay between the creation of a document and its availability to others may occur. Third, bit mapped images created by scanning become distorted when scaled, rotated or otherwise transformed. Fourth, in order for text to be searchable in a scanned document, the scanned document must be processed by optical character recognition (OCR) software.
Another problem that may be encountered with data storage is that data integrity may be compromised, either intentionally or accidentally, between the time when the data are stored and the time when the data are used. If the data are being used to obtain regulatory or administrative approval, some assurance of the integrity of the data may be required.
SUMMARY
The visual form of data may be received from a computer program and may be stored in a database. The visual form of the data may be received, for example, in response to a print operation by the computer program or by some other operation such as a cut and paste sequence of operations or by sending the data to another application. The visual form of the data may be stored as a vector image that permits scalability. The visual form of the data may be stored with other identifying information or tags in the database to facilitate searching of the database. The data in the database may be encoded in a manner that ensures data integrity and that permits detection of when data has been compromised. In one embodiment, a service layer application is provided to control access to the database by performing encoding and decoding of the data in the database. The service layer may have an application programming interface that permits many applications to have access to the database. Another application may be provided for accessing the visual form of the data from the database and for providing this data to another computer program. Such an application permits a user to create compound documents from data in the database using the other computer program.
Accordingly, the following represent some of the aspects of the invention, either alone or in any combination together. The various aspects of the invention may be as a computer-implemented process, computer system or a computer program product with computer-readable code encoded on a tangible information recording or transmission medium. Yet further aspects of the invention will be apparent from the following detailed description of an example implementation, and modifications thereto.
In one aspect, the visual form of information is captured from an application executed on a computer into a database. The visual form of the data is received from the application. Tags corresponding to the visual form of the data also are received. The visual form of the data as a vector image and the tags are stored into the database.
In another aspect, the database which stores the visual form of data from an application executed on a computer may include a first table for storing tags corresponding to the visual form of the data and a reference to the visual form of the data and a second table for storing the visual form of the data as a vector image with a reference to the visual form of the data.
In another aspect, a database in which visual form of data from applications executed on one or more computers are stored as vector images is accessed. The database may be searched to identify one or more vector images. The identified vector images are sorted according to tags associated with the identified vector images. A user is permitted to select one or more of the identified vector images, which are then displayed. The displayed vector images may be scaled and the scaled vector image is displayed. Text in the selected vector images also may be searched.
In another aspect, a selected portion of visual form of data may be sent from a first application to a second application. An indication of a selected area of the visual form of the data is received in the first application. An indication of the second application also is received. K
