System and method for generating meta-data for a product is disclosed. An artifact repository stores first artifacts for building the product. The artifact repository stores first meta-data for one or more of the artifacts in the repository. A build manager builds second artifacts for the product from source code and one or more of the first artifacts based on information in a project script. The build manager is adapted to combine the first meta-data for each of the one or more of the first artifacts used to build the second artifact to form second meta-data for each of the second artifacts.

Meta-data for single development test environment

System and method for forming a cloud appliance. The system includes a management server, an artifact repository, a continuous integration server, and build managers. The management server includes source code and a project script for forming the cloud appliance. The artifact repository stores artifacts required to build the cloud appliance and artifacts that comprise the built cloud appliance. The continuous integration server manages a build process, unit test process, and deployment process based on the project script. The build managers build the source code for customizing the virtual machine and store the built source code as the second artifacts in the artifact repository. The continuous integration server instantiates the virtual machine from template and customizes the virtual machine to form a customized virtual machine using the artifacts specified in the project script, a customization process for each of the artifacts based on a type of the artifact.

Single development test environment

A method for enabling database access to an OLE DB compatible database by a client using a JAVA JDBC Application Program Interface. A JDBC Driver program provides a bridging functionality between the using JDBC client and the OLE DB database.

Method for accessing object linking-embedding database data via JAVA database connectivity

The method of the present invention is useful in a computer system executing a Java application and a hierarchical database. The program executes a method for providing data access from the Java application to the hierarchical database. The method includes the steps of determining JDBC type, Java class name, and metadata values for the Java application to represent a given column in a result set on the hierarchical database. Next, there is a closing of all embedded result sets for the column.

Method for accessing hierarchical data via JDBC

An improved computer-implemented method is disclosed, which maintains a version history of objects in a repository. Modifications to property values and links are tracked with respect to versions of a model. The method includes the steps of maintaining a start version and a list of end versions for each object in the model and maintaining a start version and a list of end versions for each attribute value in the model. Moreover, in response to a request for objects in a class with respect to a current version, only those objects whose start version is in the history of the current version and whose end versions are not in the history of the current version are retrieved. Also, in response to a request for attribute values of an object with respect to a current version, only those values whose start version is in the history of the current version and whose end versions are not in the history of the current version are retrieved.

Method for maintaining a version history of objects in a repository

A computer-implemented method is provided for merging a source version into a target version of a model in an object oriented repository. The method comprises the steps of building a first list as a collection of versions that occur only in a history of the source version; and, building a second list as a collection of versions that occur only in a history of the target version. Next, a dual history is created as a union of the first and second lists. After this, either the first or the second list is identified as the non-preferred history wherein either the source or the target version is preferred. The first list is then added to the history of the target version. Any conflicts occurring in the dual history are next reported; and, such conflicts are resolved by adding the target version to a list of end versions on each conflicting attribute value and link occurring in the non-preferred history.

Method for merging versions of a model in an object oriented repository

The method of the present invention is useful in a computer system having a user interface, a CPU, a memory, at least one disk drive and an object database stored in one or more disk drives. The method is used to derive an object database independent standard API from the description of the object in the object database. The method of the present invention, which is executable by the computer system, comprises the following steps: for each database type, TYPE, declared in the database, executing the following steps: opening a file on said at least one disk drive and storing therein the results of the following steps; declaring a surrogate class sTYPE; for each property, PROP, of TYPE, declaring accessors and mutators; declaring construct and destruct member functions; for each operation, OP, of TYPE, declaring member functions; and, declaring special functions.

Method for providing object database independence in a program written

In a computer system having a user interface, a memory, a repository and a database, a repository program operating in the computer system for accessing the database, the repository program executing a method for supporting modeling, the method comprising the steps of examining a collection of types forming a model; sorting object types into data and persistent type objects; creating all data type objects and adding to a collection of all objects owned by the model; creating all persistent type objects and adding to a collection of all objects owned by the model; initializing all persistent type objects in the collection of objects.
