the Age of technology, the Digital Age, has been transforming sales trends and processes. As more companies start incorporating technology into their business strategies, the competition gets tougher and more demanding. Using outdated technology has been a problem for many small business owners, as it hurts overall business performance. the researchers have found one seller who would still use an outdated system by manually sending out forms and updating her database, which could cost her potential clients and sales. this paper then aims to solve that problem by analyzing information on that system and determining its waste. the researchers expect an increase in efficiency, as they use MS Access to create a form and a database for the online seller, aside from adding a new feature that will allow customer queries. the researchers have found that implementing the MS Access database in the system of individual online sellers increases their efficiency and a lesser chance of making a mistake.

the Houma Alliance Book contains official characters from the Jin State (approximately 550 BC) and is also the earliest discovered calligraphy using writing brushes in the archaeological community. As an ancient handwriting system, HAB stores a wealth of information that helps us understand the world, the history of the Jin State in the Spring and Autumn Period, the evolution of calligraphy, and more. However, HAB was only discovered approximately sixty years ago, and there is little research on it. Due to environmental corrosion, the HAB has become less legible, making the technology for automatic detection and recognition of characters an important solution. this paper aims to make an Houma Alliance Book facsimiles database namely FADB, and to carry out detection and recognition. the database contains 655 facsimiles with 327 classes of Chinese characters. More specifically, it has the individual characters from the 655 facsimiles. then, this paper uses a deep learning network to recognize these samples. Experiments are performed on the new database. the experimental results provide new baseline results of detection and recognition for this new database and demonstrate the feasibility of our dataset.

Compared with traditional antennas, phased array antennas with key structural components such as multi Vilvadi oscillators and grid plates have advantages such as high gain and high directional ability. Due to the need for a large number of structural components in phased array antennas, this will affect the performance and assembly accuracy of the assembled antenna. How to quickly and reasonably provide an assembly error distribution plan is the key to improving the performance of phased array antennas. this paper proposes a database based on geometric feature extraction of contact surfaces and finite element analysis of contact stress to obtain an optimized assembly plan for key components of phased array antennas, which requires the use of a large number of key components. Considering the real-time updated assembly data, a reasonable assembly path planning method was planned to avoid assembly interference. the simulation results show that this method can significantly improve assembly efficiency and provide a reasonable assembly error distribution scheme.

the continuous development of GPS-enabled equipments and location-based services has brought new challenges to the storage and management of trajectory big data. Traditional database system such as PostgreSQL/PostGIS to cope withthis demand. Meanwhile, distributed trajectory management systems based on NoSQL have attracted increasing attention from both industry and acdemia. However, to the best of our knowledge, there are not many reseach discussing the comparision of these systems. this paper aiming at filling this gap by comparing the performance of the representitive relational database component PostGIS and the distributed NoSQL data management system GeoMesa in various range query and multi concurrent access scenarios through experimental analysis. the experimental results show that GeoMesa outperforms the relational spatial database component PostGIS in the large number of access results and multi-user access scenarios.

this paper presents the design idea of building the infrastructure information management system based on remote sensing data. Withthe characteristics of the systems massive remote sensing data and the comprehensive application problem of heterogeneous data, unify the design specifications of the database is the most important. then several data tables are designed by category. Finally some key technologies such as data storage are discussed . this infrastructure information management software has solved the problem of smoothly and quickly call of the massive underlying and heterogeneous data. It has realized the functions of infrastructure plotting, process supervision, statistical analysis and two-dimensional and three-dimensional visualization. this system has been applied in the professional domain to improve the work efficiency.

In contemporary software development, database performance significantly influences the stability, scalability, and responsiveness of applications. Withthe growing complexity of application scenarios and the continuous rise in concurrent access, performance testing has become a crucial technical component for ensuring the efficient operation of databases. As a widely used relational database, optimizing the performance of MySQL is essential to meet high-load business requirements. this paper systematically explains how to use LoadRunner to evaluate the performance of MySQL databases from boththeoretical and practical perspectives. the content covers the whole process from the formulation of test plans, the development and optimization of scripts, the design of test scenarios, to the execution of performance tests and the analysis of results, and analyzes the identification and optimization strategies of database performance bottlenecks in combination with actual cases. through reasonable test design and scientific analysis methods, it aims to provide the development team with a set of operable and replicable database performance testing and optimization solutions to help improve the stability and overall performance of the database and provide strong support for the efficient operation of modern applications.

the Ministry of Health of Indonesia has referred to pre-eclampsia as one of the most severe diseases affecting women. As an urgency, it is crucial to administrate pre-eclampsia cases for disease prevention as a long-term national healthcare strategy. Regarding health science, case data was significant in developing research and innovation. However, the main problem regarding pre-eclampsia case administration is data handling, recording, and management incompetence. Hence, this research proposed a conceptual design of a database for pre-eclampsia case administration. the proposed design covered conceptual, logical, and physical design. We elaborate the concept into three concepts of pre-eclampsia disease: pre-treatment, treatment, and post-treatment. this study proposed a solution to gain more data and study pre-eclampsia disease in Indonesia.

For cell culture processes that are time-consuming to observe and analyze manually and prone to bacterial contamination. this paper presents a method for monitoring and realtime analysis of small numbers of cells in culture that combines lensless imaging techniques with microfluidics. the method uses microfluidics to create the microcavity environment required for cell growth, and images of the cells are taken at regular intervals using a lensless holographic imaging system. Information on the morphology, size, position, and number of cells is obtained by autofocus and holographic reconstruction of the collected hologram. A cell growthdatabase is created based on all the image frame data. Finally, the growthdatabase is post-processed to provide information such as cell growth and proliferation curves, trajectory tracking, and temperature and humidity profiles of the system environment. By monitoring the yeast in culture for 10 hours, a database of cell growth at 2-minute intervals was created, further growth curves for the yeast were obtained, and the cells were successfully tracked. the method's validity has been verified in this paper, providing a new solution for fully automated culture monitoring and analysis of small numbers of cells.
