The Electronic Warfare Integrated Reprogramming (EWIR) database is the primary Department of Defense source for technical parametric performance data on noncommunications emitters. It has been identified by the National Air Intelligence Center as difficult to use in its current hierarchical database form. There are two problems addressed by this thesis. FIrst, is an object- oriented EWIR database a superior method for managing complex electronic warfare data collections? Second, is the prototype Object-Oriented Interface (O-OI) developed at the Laboratory for Database System Research in the Naval Postgraduate School capable of supporting a complex object-oriented database such as EWIR? To answer these questions, a subset of the EWIR Objective-Oriented Specification developed in a separate thesis is implemented on the O-OI. Using the O-OI Data Definition Language, the object-oriented EWIR database schema and its associated record data are stipulated and loaded to create the live database. Using the O-OI Data Manipulation Language, nine EWIR transactions are elaborated and executed.

Narrative data processing and database updating are examined from the viewpoint of interaction with other processes in an automated data fusion system. Methods are outlined for using production rules (if-then rules) in the processing of the narrative data and for integrating such a process with other rule-based data-fusion processes. Database updating methods which employ a 'history file' are processed. An experimental rule-based program compares event reports for redundancies, combines reports of the same event and retires old data into a history file in a form useful for event reconstruction and evaluation. A number of related areas of investigation are suggested for future research. (Author)

Replicated architecture has been proposed as a way to obtain acceptable performance in a multilevel secure database system. This architecture contains a separate database for each security level such that each contains replicated data from lower security classes. The consistency of the values of replicated data items must be maintained without unnecessarily interfering with concurrency of database operations. This paper provides a protocol to do this that is secure, since it is free of covert channels, and also ensures one-copy serializability of executing transactions. The protocol can be implemented with untrusted processes for both concurrency and recovery.

Swift rates of scientific-technical evolution demand modern technologies of information storing and processing for diverse resources management, for example in science and education domain. For solving of this task the ontological approach was used and “Ontology-based Portal for Management and Evaluation of scientific and Educational Resources of Ukraine” was created to reveal implicit domain knowledge, detect conflicts and control the correspondence of the HEI`s activity to the legislative base of Ukraine and society needs

This Coastal and Hydraulics Engineering Technical Note (CHETN) describes coupling of the US Army Engineer Research and Development Center (ERDC) Wave Information System (WIS) database to Wavenet, the first module of MetOcnDat (Meteorological and Oceanographic Data or Metocean data) management and analysis system. Part 2 in the WaveNet technical note series provides a step-by-step procedure for users to access, process and analyze wave and wind data from the WIS database. Wilson et al. (2012) provided a detailed description of WaveNet in the Part 1 companion CHETN and demonstrated the utility of WaveNet for National Data Buoy Center (NDBC) wave data. WaveNet is a web-based Graphical-User-Interface (GUI) data management tool that allows users to access, process and analyze wave and wind data from different metocean data sources. TideNet is the next addition to the MetOcnDat system that will provide access and similar functionality for water level and current data. Once the user identifies a data need for a time interval, WaveNet performs data processing on-the-fly to check the availability, quality and consistency of data. It allows users to extract data to download, analyze and prepare input files for numerical wave models, and provides tabular and graphical information for project planning and design reports. WaveNet addresses a basic need of the Corps coastal modeling and planning missions by acquiring metocean data and providing analysis methods to minimize the complexity and uncertainty involved in data processing. This CHETN provides a guide for users to access the WIS database using WaveNet and step-by-step instructions that demonstrate processing and analysis of WIS data for project planning, design and evaluation studies, as well as the generation of input files for numerical wave models.

The Marine Air Command and Control System execution of Direct Air Support is based on the concept of centralized command and decentralized control. It is completed manually using standardized procedures and controls to ensure responsiveness in higher dynamic situations. This thesis investigates the issues in developing and implementing an automated database application for receiving, processing, disseminating, and recording information as it pertains to the Air Tasking Order within the Direct Air Support Center. A relational database is proposed using Entity-Relationship modeling. A simple prototype of the system is implemented in dBASE IV to demonstrate proof of concept. The major benefits of the database approach is that databases are dynamic and can evolve with changing needs.

This report gives a detailed summary of research work completed under Air Force Research Laboratory (AFRL) grant 53925, over the time period (April 12, 2010 April 10, 2012). There are two main aspects of the work completed. First was the collection and annotation of a large open source data base of speech passages from web sites such as You Tube. 300 passages were collected in each of three languages English, Mandarin, and Russian. Approximately 30 hours of speech were collected for each language. Each passage has been carefully transcribed at the phrasal level by human listeners. Each passage was originally transcribed and then checked and the transcription edited as needed by at least two additional native language listeners. The English and Mandarin were then forced aligned and labeled at the phonetic level using a combination of manual and automatic methods. The Russian passages have not yet been marked at the phonetic level. Another phase of the work was to explore several algorithmic methods for improving automatic speech recognition (ASR) for this intelligible but challenging data base. Note that the body of the report has four main sections plus appendices which introduce, describe, and summarize a portion of the work.

The objectives of the User's Manual for the Inter-Service/Agency Automated Message Processing Exchange (I-S/A AMPE) Data Base Update is to provide the user's non-ADP personnel with the information necessary to use the system effectively. I-S/A AMPE will be the departments of Defense's (DoD's) replacement for the Service Agency Automated Message Processing Exchanges (AMPEs) and the Automatic Digital Network (AUTODIN) switching centers. The software allows for data retrieval and update of the data base. The project sponsor and user is the Defense Communications Engineering Center (DCEC) and the operating center that will run the completed computer programs is the DCEC computer facility. The following is a list of applicable documents.

By: Radical Rakhman Wahid Event: PyConZA 2021 URL: https://2021.za.pycon.org/talks/35-optimize-your-database-operations-with-asynchronous-processing/ The bottleneck of a program can be caused by many reasons like bad data structure/logic/algorithm implementation, network connection, I/O bound operations, processor, etc. Database operations is kind of I/O bound operation which means, when it comes to the DB query program will waiting the result from another separate process. If the bottleneck is from the DB operations then you should try asynchronous processing :) In Python, asynchronous support first introduced in version 3.4. Now the asynchronous Python is getting better by increasing third party packages. In this talk I'll cover the explanation about asynchronous DB operations in Python and then hands-off to show the results of using the asynchronous code compare with the synchronous one. Postscript : Since I work day to day using the ORM (like SQLAlchemy) and PostgreSQL is our main DBMS (for product development), so the async in DB ops will be covered with SQLAlchemy and PsycoPG/AsyncPG as well. Audience: Anyone who work with database operations (data scientists, back-end engineers, students/researchers, etc.) What will they get out of it: - Clear concept and application of asynchronous DB operations that can be applied in production environment, as well. - A modern way to optimize query DB time with a minimum resource.

This paper considers the processing of digital library queries, consisting of a text component and a structured component in distributed environments. The paper concentrates on the processing of the structured component of a distributed query. A method is proposed to identify the databases that are likely to be useful for processing any given query and to determine the tuples from each useful site which are necessary for answering the query. In this way, both the communication cost and the local processing costs are saved. One common characteristic of these "k" nearest neighbors queries is that it is not necessary to obtain all the "k" nearest neighbors; it is often sufficient to get most of the "k" neighbors. Experimental results are provided to demonstrate that most of the "k" nearest neighbors (85% to 100%) are obtained using this approach. An average accuracy rate of 94.7% is achieved when the 20 closest neighbors are desired. (Contains 15 references.) (AEF)

This report describes the design and implementation of a prototype database system that was created to help the Engineering Directorate manage its Individual Development Plan (IDP) information. The database system was designed to meet the customers current needs and to be easily modifiable in the event that new needs are identified. The database uses a relational data model and the database manager includes operations for data retrieval and data management. Since mid October 1994, the database system has been used to process the directorates' FY95 IDP information.

This paper outlines a general philosophy and framework for the specification of a data model. Extracts from scenarios that have been developed for specification of several well-known data models (e.g., DBTG, relational, TDMS) are given and discussed. These extracts are preliminary and incomplete, but they are used to illustrate the feasibility of the Data Model Processor Approach. The scenarios are intended for implementation of an augmented positional processor that will be able to support different data models and, through transformation, serve in defining and testing new DBMS standards.

The purpose of this section is to specify the procedure for making changes to the ERIC database after the data involved have been announced in the abstract journals RIE or CIJE. As a matter of general ERIC policy, a document or journal article is not re-announced or re-entered into the database as a new accession for the purpose of accomplishing a change to its record (e.g., a Level of Availability change). It is not desirable to create essentially duplicate records in the database because of the long term adverse effect of such duplicates on retrieval activities. It is preferable to make a change to an existing record and to see that the database files distributed to vendors are eventually updated with such changed records. This manual states the policies for making changes, defines acceptable versus non-acceptable changes, and details the procedures each component of the ERIC system must follow in order to see that different kinds of database changes are accomplished properly.

The Boston College Institute for Scientific Research (ISR) has conducted innovative research using tools, analysis techniques, and database development to support the Air Force Research Laboratory s (AFRL) nuclear monitoring program. The innovative research objectives of this task have been directed toward applying waveform modeling techniques to earthquakes and explosions at locations of interest to the community where both teleseismic and regional waveform data are available. Moderate to large earthquake sources provide high resolution ground truth information for regional studies of earthquake and explosion phenomenology. Some of our major efforts included the New England Damage Experiment where the question of shear wave generation mechanisms for explosive sources was addressed. Another major effort included the determination of attenuation parameters in La Paz, Bolivia for improved seismic phase identification.

The main objective of this research was to explore and refine methods for detailed phonetic labeling (English or Russian) and character level labeling (Mandarin). Much of the work involved new front end signal processing methods designed to improve acoustic phonetic representations for speech. This resulted in recognition rates for TIMIT (English) of 74%, among the highest reported in the literature. A complete character recognition system for Mandarin was developed and tested. Character recognition rates as high as 88% were obtained, using an approximately 40 training databases. For the case of Russian, a system for automatically converting Russian to morphemes, a kind of base syllable, was created and tested. A suite of tools for front end processing, automatic forced alignment, and a complete automatic recognition system are described.

We show that database schema validation and update processing problems such as view updating, materialized view maintenance, integrity constraint checking, integrity constraint maintenance or condition monitoring can be classified as problems of either abductive or deductive nature, according to the reasoning paradigm that inherently suites them. This is done by performing abductive and deductive reasoning on the event rules [Oli91], a set of rules that define the difference between consecutive database states In this way, we show that it is possible to provide methods able to deal with all these problems as a whole. We also show how some existing general deductive and abductive procedures may be used to reason on the event rules. In this way, we show that these procedures can deal with all database schema validation and update processing problems considered in this paper.

This is done by performing abductive and deductive reasoning on the event rules [Oli91], a set of rules that define the difference between consecutive database states In this way, we show that it is possible to provide methods able to deal with all these problems as a whole. We also show how some existing general deductive and abductive procedures may be used to reason on the event rules. In this way, we show that these procedures can deal with all database schema validation and update processing problems considered in this paper.

This Coastal and Hydraulics Engineering Technical Note (CHETN) describes the second module of the MetOcnDat (Meteorological and Oceanographic or Metocean) system, called TideNet. The MetOcnDat modular system in development consists of toolboxes for waves, tides, and river flow databases that will facilitate conversion of data used in input files for numerical models and provide tabular and graphical information for project planning and design reports. TideNet is a web-based Graphical-User-Interface (GUI) data management tool that allows users to access, process, and analyze tide data available from different tidal databases. This first application of TideNet deals only with tide data from the National Weather Service (NWS) database used in various coastal, ocean, and marine engineering applications. Metocean data include winds, waves, tides (water levels and currents), and river discharges. The first two Technical Notes (TNs) in the MetOcnDat system series (Demirbilek et al. 2013; Wilson et al. 2012) described the application of WaveNet, a companion module of TideNet, for the National Data Buoy Center (NDBC) buoy and Wave Information Stduy (WIS) databases. The TideNet is a web-based GUI that provides users with GIS mapping tools to query tide data sources in a desired geographic region of USA and its territories. Users can select a tide data source through the Google Map interface to view data and parameters of interest. The utilities of TideNet available at the selected tide data source can query the data source, then plot, analyze, and extract tidal information based on a user-specified time window and output data in different formats for engineering applications. TideNet has additional post-processing capabilities to produce tables and figures and prepare input files for numerical models.

We present a complex data handling system for the COMPASS tokamak, operated by IPP ASCR Prague, Czech Republic [1]. The system, called CDB (Compass DataBase), integrates different data sources as an assortment of data acquisition hardware and software from different vendors is used. Based on widely available open source technologies wherever possible, CDB is vendor and platform independent and it can be easily scaled and distributed. The data is directly stored and retrieved using a standard NAS (Network Attached Storage), hence independent of the particular technology; the description of the data (the metadata) is recorded in a relational database. Database structure is general and enables the inclusion of multi-dimensional data signals in multiple revisions (no data is overwritten). This design is inherently distributed as the work is off-loaded to the clients. Both NAS and database can be implemented and optimized for fast local access as well as secure remote access. CDB is implemented in Python language; bindings for Java, C/C++, IDL and Matlab are provided. Independent data acquisitions systems as well as nodes managed by FireSignal [2] are all integrated using CDB. An automated data post-processing server is a part of CDB. Based on dependency rules, the server executes, in parallel if possible, prescribed post-processing tasks.

Future NASA earth science missions, including the Earth Observing System (EOS), will be generating vast amounts of data that must be processed and stored at various locations around the world. Here we present a stepwise-refinement of the intelligent database management (IDM) of the distributed active archive center (DAAC - one of seven regionally-located EOSDIS archive sites) architecture, to showcase the telecommunications issues involved. We develop this architecture into a general overall design. We show that the current evolution of protocols is sufficient to support IDM at Gbps rates over large distances. We also show that network design can accommodate a flexible data ingestion storage pipeline and a user extraction and visualization engine, without interference between the two.
