Conventional file-based engineering design data for an engineering model are represented by a plurality of components. Each component has a unique identifier, a set of fields, each field having a data type and a data value, and a program which interprets and modifies the fields. The plurality of components are stored in a repository of a server. The repository also stores a history of any changes made to the components. A plurality of client computers are bidirectionally connected to the server. Each client computer may obtain the current version of the components and may send locally edited versions of the components back to the server to replace the current versions in the repository. At the client computer, the user interacts with the components using conventional file-based software. Before locally edited versions of the components are committed to the server to replace the current versions, a synchronization and merging process occurs whereby the latest version of the components are downloaded to the client computer and are compared to the locally edited version of the components to detect resolvable (compatible) and unresolvable (incompatible) conflicts therebetween. The commit process is performed only if no unresolvable conflicts exist between the two versions of the components. To facilitate translation between file-based data and components, a schema is written to "wrap" each of the engineering file formats. Each schema is a set of classes that capture all of the information in the file-based data.

The method comprises monitoring in runtime active processes running on a computing device, extracting unique identifier(s) of each of the active processes which maps the active process to executable binary file(s) containing executable code of the active process, monitoring in runtime creation and modification of data files hosted by the computing device, identifying executable binary files among the data files, monitoring concurrent operation of logical sensors which detect malicious behavioral patterns of the active processes and maintain one or more lists of malicious behavioral pattern findings, and detecting malicious active process(es) of a malware from the active processes and self-replicating executable binary file(s) of the malicious active process(es) according to a match between the respective unique identifier(s), the malicious behavioral pattern findings and at least one the executable binary files.

Troubleshooting virtual environment deployment based on two level file system signatures, in one aspect, may include creating a first level file system signature including a set of file names of files in an image of a virtual machine taken at a point in time and associated status of the files as compared with an image of the virtual machine taken at a preceding point in time. A second level file system signature may be created using file content differences of the files having modified status in the set of file names. The first level file system signature may be compared with a first level file system signature pattern associated with one or more previous deployment of the same software and related to the same point in time. Optionally, the second level file system signature may be compared with a second level file system signature pattern.

The invention discloses a method and a terminal for improving the utilization ratio of a memory space. The method comprises steps of A, monitoring the available space in the memory space, judging whether the available space is smaller than a preset space or not; if yes, starting a file system compression mode, and scanning files in the memory space; if not, stopping monitoring; B1, judging whether the currently scanned file is a compressible file or not; if yes, executing step C1; if not, scanning the next file, repeating step B1 until all the files are completely scanned, and exiting from the file system compression mode; and C1, compressing and marking the compressible file, scanning the next file, and returning to step B1. All the files in the memory space are appropriately and selectively compressed through the method, the utilization ratio of the memory space is improved, and a user does not need to select the files to perform a plurality of times of compression, so that the use by users is facilitated, and a user experience effect is improved.

The present invention relates to a method, and system for implementing the method, for performing incremental validation of an XML document with respect to XML Schema key and keyref constraints, and handling the semantics dictated by the XML Schema specification. Several operations are defined that change the content of a document, i.e., add or remove nodes, or change the value of existing nodes. The present invention verifies whether performing such an operation would violate key or keyref constraints, and allows changing the document only if the operation maintains the validity of the document with respect to the constraints. The verification traverses only the parts of the document that may be affected by the change operation, and not the whole document. The invention maintains, in an efficient manner, data structures that hold information relevant to the validation of key and keyref constraints.

Techniques are disclosed relating to create a configuration for a database system. In some embodiments, program instructions of a change set for an application are received from a source code management (SCM) repository. In response to the receiving, a build process is performed that includes causing compilation of the received program instructions to produce program instructions executable to run the application. The build process also includes provisioning the configuration with a schema by retrieving a first set of metadata defining the schema and issuing corresponding data definition language (DDL) instructions to create the schema in the configuration. The build process includes provisioning the configuration with data by retrieving a second set of metadata defining the data and issuing corresponding data manipulation language (DML) instructions to insert the data into the configuration and storing the provisioned configuration in a repository as one of multiple configurations associated with multiple received change sets.

A system formats and normalizes data stored in received files. A data processing engine identifies a filetype and format of the file based on samples of the file contents. The system detects a schema of the file to determine the datatypes and locations of data within the file. The schema detection process may depend on the identified filetype of the file. Once a filetype and schema have been determined, the system can reformat data stored within different sections of the file in view of the datatypes. The formatted file is stored in a data lake with other files received by the system. The formatting process can involve normalization of certain datatypes, which facilitates access of the data later by a user querying the data stored in files at the data lake.
