摘要:
In a data dictionary directory system, the definition information to be registered in a dictionary is registered being divided into several definition units. A data base system registers the definition information and confirms the coordination of the contents of definition among the definition units. The definition information is registered without confirming the coordination. The coordination is confirmed when it becomes necessary to confirm the coordination among the definition informations registered in the dictionary.
摘要:
In a database having a dictionary/directory, the dictionary/directory is processed to form a directory using information in the dictionary, or is processed for other purposes. A process record including identification information associated with the process is stored in the dictionary/directory. In a dictionary deletion process, the stored record is designated and read out such that associated information indicated by the process record is also deleted in a batch manner.
摘要:
In a database system having a dictionary/directory for collective management of definition information of the database system, when an application program is compiled to generate an object module, it is confirmed, by referring to the definition information stored in the dictionary, if a database access instruction in the application program is correctly operable. The confirmed definition information is incorporated within an object module which is edited to generate a load module. During execution of the load module, a database access control is effected using the definition information of the database system in the directory as well as the definition information incorporated at the compiling stage.
摘要:
A process and apparatus is described for the processing of thin films on semiconductor substrates using one or more liquid precursor sources wherein the liquid precursor source with the highest vapor pressure is first vaporized and then introduced as a vapor into a common manifold connected to a processing chamber, with the point of introduction being spaced away from the processing chamber. A second liquid precursor source, having a vapor pressure lower than the first liquid precursor source, is then introduced in vaporized form into the manifold at a point closer to the processing chamber. This is repeated for each liquid precursor source, with each succeeding liquid precursor source having the next lower vapor pressure being introduced in vaporized form into the manifold at a point closer to the processing chamber than the previous liquid precursor source. A temperature gradient may then be maintained along the manifold with the temperature gradually increased in a direction toward the processing chamber while still mitigating premature boiling of the liquid precursor sources prior to vaporization, or condensation of already vaporized liquid precursor sources or components.
