This document provides a review of research on temporal extensions to the Structured Query Language (SQL) for databases. It discusses how early research in the 1990s led to proposals for extending SQL to support temporal data, known as TSQL2. While TSQL2 failed to be included in the SQL:1999 standard, aspects of temporal support were introduced in SQL:2011, including system-versioned tables and application-time period tables. However, there remain opportunities to further enhance temporal functionality in SQL. The document aims to consolidate information on past and current temporal extensions to SQL to help align future research and identify remaining gaps.
TOP NEWSQL DATABASES AND FEATURES CLASSIFICATIONijdms
Versatility of NewSQL databases is to achieve low latency constrains as well as to reduce cost commodity
nodes. Out work emphasize on how big data is addressed through top NewSQL databases considering their
features. This NewSQL databases paper conveys some of the top NewSQL databases [54] features collection
considering high demand and usage. First part, around 11 NewSQL databases have been investigated for
eliciting, comparing and examining their features so that they might assist to observe high hierarchy of
NewSQL databases and to reveal their similarities and their differences. Our taxonomy involves four types
categories in terms of how NewSQL databases handle, and process big data considering technologies are
offered or supported. Advantages and disadvantages are conveyed in this survey for each of NewSQL
databases. At second part, we register our findings based on several categories and aspects: first, by our
first taxonomy which sees features characteristics are either functional or non-functional. A second
taxonomy moved into another aspect regarding data integrity and data manipulation; we found data
features classified based on supervised, semi-supervised, or unsupervised. Third taxonomy was about how
diverse each single NewSQL database can deal with different types of databases. Surprisingly, Not only do
NewSQL databases process regular (raw) data, but also they are stringent enough to afford diverse type of
data such as historical and vertical distributed system, real-time, streaming, and timestamp databases.
Thereby we release NewSQL databases are significant enough to survive and associate with other
technologies to support other database types such as NoSQL, traditional, distributed system, and semirelationship
to be as our fourth taxonomy-based. We strive to visualize our results for the former categories
and the latter using chart graph. Eventually, NewSQL databases motivate us to analyze its big data
throughput and we could classify them into good data or bad data. We conclude this paper with couple
suggestions in how to manage big data using Predictable Analytics and other techniques.
This document summarizes a study that compares the performance of time series databases using real-world datasets versus synthetic datasets. The study measures three key performance metrics - data loading throughput, storage space usage, and query latency - for different time series databases when ingesting and querying both real and synthetic time series data. The results show significant differences in performance between real and synthetic datasets for data injection throughput and query execution times. Specifically, databases perform differently when handling real-world versus synthetic datasets, indicating that benchmarks using only synthetic data may not accurately represent real-world database performance for time series applications.
BI-TEMPORAL IMPLEMENTATION IN RELATIONAL DATABASE MANAGEMENT SYSTEMS: MS SQ...lyn kurian
Traditional database management systems (DBMS) are the computation
storage and reservoir of large amounts of information. The data accumulated by these
database systems is the information valid at present time, valid now. It is the data that
is true at the present moment. Past data is the information that was kept in the
database at an earlier time, data that is hold to be existed in the past, were valid at
some point before now. Future data is the information supposed to be valid at a future
time instance, data that will be true in the near future, valid at some point after now.
The commercial DBMS of today used by organizations and individuals, such as MS
SQL Server, Oracle, DB2, Sybase, Postgres etc., do not provide models to support and
process (retrieving, modifying, inserting and removing) past and future data.
The implementation of bi-temporal modelling in Microsoft SQL Server is important
to know how relational database management system handles data the bi-temporal
property. In bi-temporal database, data saved is never deleted and additional values
are always appended. Therefore, the paper explores one of the way we can build bitemporal handling of data. The paper aims to build the core concepts of bi-temporal
data storage and querying techniques used in bi-temporal relational DBMS i.e., from
data structures to normalized storage, and to extraction or slicing of data.
The unlimited growth of data results relational data to become complicated in terms
of management and storage of data. Thus, the developers working in various
commercial and industrial applications should know how bi-temporal concepts apply to relational databases, especially due to their increased flexibility in the bi-temporal
storage as well as in analyzing data. Thereby, the paper demonstrates how bi-temporal
data structures and their operations are applied in Relational Database Management
System
The document discusses temporal databases, which store information about how data changes over time. It covers several key points:
- Temporal databases allow storage of past and future states of data, unlike traditional databases which only store the current state.
- Time can be represented in terms of valid time (when facts were true in the real world) and transaction time (when facts were current in the database). Temporal databases may track one or both dimensions.
- SQL supports temporal data types like DATE, TIME, TIMESTAMP, INTERVAL and PERIOD for representing time values and durations.
- Temporal information can describe point events or durations. Relational databases incorporate time by adding timestamp attributes, while object databases
Analysis and evaluation of riak kv cluster environment using basho benchStevenChike
This document analyzes and evaluates the performance of the Riak KV NoSQL database cluster using the Basho-bench benchmark tool. Experiments were conducted on a 5-node Riak KV cluster to test throughput and latency under different workloads, data sizes, and operations (read, write, update). The results found that Riak KV can handle large volumes of data and various workloads effectively with good throughput, though latency increased with larger data sizes. Overall, Riak KV is suitable for distributed big data environments where high availability, scalability and fault tolerance are important.
Relational databases are a technology used universally that enables storage, management and retrieval of
varied data schemas. However, execution of requests can become a lengthy and inefficient process for
some large databases. Moreover, storing large amounts of data requires servers with larger capacities and
scalability capabilities. Relational databases have limitations to deal with scalability for large volumes of
data. On the other hand, non-relational database technologies, also known as NoSQL, were developed to
better meet the needs of key-value storage of large amounts of records. But there is a large amount of
NoSQL candidates, and most have not been compared thoroughly yet. The purpose of this paper is to
compare different NoSQL databases, to evaluate their performance according to the typical use for storing
and retrieving data. We tested 10 NoSQL databases with Yahoo! Cloud Serving Benchmark using a mix of
operations to better understand the capability of non-relational databases for handling different requests,
and to understand how performance is affected by each database type and their internal mechanisms.
Converting UML Class Diagrams into Temporal Object Relational DataBase IJECEIAES
Number of active researchers and experts, are engaged to develop and implement new mechanism and features in time varying database management system (TVDBMS), to respond to the recommendation of modern business environment.Time-varying data management has been much taken into consideration with either the attribute or tuple time stamping schema. Our main approach here is to try to offer a better solution to all mentioned limitations of existing works, in order to provide the nonprocedural data definitions, queries of temporal data as complete as possible technical conversion ,that allow to easily realize and share all conceptual details of the UML class specifications, from conception and design point of view. This paper contributes to represent a logical design schema by UML class diagrams, which are handled by stereotypes to express a temporal object relational database with attribute timestamping.
This document provides a literature review of NoSQL databases. It discusses how the rise of big data from sources like social media, sensors, and surveillance footage has led organizations to adopt NoSQL databases that can handle large volumes of unstructured data more efficiently than traditional relational databases. The document evaluates several popular NoSQL databases like MongoDB, Cassandra, and HBase, categorizing them as either document stores, column family databases, or key-value stores. It also provides examples of major companies that use NoSQL and discusses factors like flexibility and scalability that have driven adoption.

The aim of this paper is to evaluate, through indexing techniques, the performance of Neo4j and
OrientDB, both graph databases technologies and to come up with strength and weaknesses os each
technology as a candidate for a storage mechanism of a graph structure. An index is a data structure that
makes the searching faster for a specific node in concern of graph databases. The referred data structure
is habitually a B-tree, however, can be a hash table or some other logic structure as well. The pivotal
point of having an index is to speed up search queries, primarily by reducing the number of nodes in a
graph or table to be examined. Graphs and graph databases are more commonly associated with social
networking or “graph search” style recommendations. Thus, these technologies remarkably are a core
technology platform for some Internet giants like Hi5, Facebook, Google, Badoo, Twitter and LinkedIn.
The key to understanding graph database systems, in the social networking context, is they give equal
prominence to storing both the data (users, favorites) and the relationships between them (who liked
what, who ‘follows’ whom, which post was liked the most, what is the shortest path to ‘reach’ who). By a
suitable application case study, in case a Twitter social networking of almost 5,000 nodes imported in
local servers (Neo4j and Orient-DB), one queried to retrieval the node with the searched data, first
without index (full scan), and second with index, aiming at comparing the response time (statement query
time) of the aforementioned graph databases and find out which of them has a better performance (the
speed of data or information retrieval) and in which case. Thereof, the main results are presented in the
section 6.
Design and implementation of the web (extract, transform, load) process in da...IAESIJAI
Owing to the recent increased size and complexity of data in addition to management issues, data storage requires extensive attention so that it can be employed in realistic applications. Hence, the requirement for designing and implementing a data ware-house system has become an urgent necessity. Data extraction, transformation and loading (ETL) is a vital part of the data warehouse architecture. This study designs a data warehouse application that contains a web ETL process that divides the work between the input device and server. This system is proposed to solve the lack of work partitioning between the input device and server. The designed system can be used in many branches and disciplines because of its high performance in adding data, analyzing data by using a web server and building queries. Analysis of the results proves that the designed system is fast in cleaning and transferring data between the remote parts of the system connected to the internet. ETL without missing any data consumes 0.00582 seconds.
Context sensitive indexes for performance optimization of sql queries in mult...avinash varma sagi
This document proposes context-sensitive indexes to optimize SQL query performance in multi-tenant and multi-application database environments. Current database architectures require indexes to be considered for all queries on a table, posing challenges for query optimization. The proposal is for applications and tenants to define their own indexes on shared tables to optimize their queries, while keeping indexes isolated from other applications and tenants for optimization purposes. The document provides background on challenges with mixed workloads and motivation for the proposal, which could lead to better optimized query processing and improved performance and scalability.
Temporal Database is the most convenient form to represent time element associated with data. Temporal validity support a unique feature of temporal database lets you associate one or more valid time dimensions with a table and have data be visible depending on its time-based validity, as determined by the start and end dates or time stamps of the period for which a given record is considered to be a valid record. This study focuses on checking and verification of temporal data using valid time dimension of temporal database. This study covers the steps for adding a valid time dimension on a table, and various methods for querying the table and retrieving records based on a specified valid time value or range with
help of Oracle 12c.
Management of Bi-Temporal Properties of Sql/Nosql Based Architectures – A Re...lyn kurian
Data engineering is the most important field in computer science engineering. Data is computed, stored and
manipulated according to the user requirement. Data can be text, picture, audio, video or document which is in various
formats. This paper deals with various database management systems that stores and manipulates data efficiently,
including banking system, scientific or commercial systems. Traditionally, we use RDBMS like MS SQL Server, IBM
DB2, Oracle, MySQL and Microsoft Access for transactional processing and analytical processing. On the advent of Big
Data, the strict RDBMS is not a customized solution on considering the performance and scalability aspects of the
Information Technology that needs today. The new era needs new technologies. Google introduced the concept of NoSQL
Databases in 2005, which led to the revolution of NoSQL databases like Noe4j, HBase, Redis, Mango DB etc. But
migration to NoSQL Databases is a challenging area for the database architects in various fields of business. Different
tools and techniques for database migration, query translation and query optimization is being adopted and the research
area is open. This paper comprises the categorization of the proposed and implemented bi-temporal databases along with
their bi-temporal properties till date.
Context-Sensitive Indexes for Performance Optimization of SQL Queries in Mult...Arjun Sirohi
This document discusses context-sensitive indexes in relational database management systems to optimize SQL query performance in multi-tenant and multi-application environments. It proposes allowing applications, tenants, and users to define their own indexes on shared database tables to optimize queries specific to them, while keeping these indexes isolated from other queries for optimization purposes. Currently, database optimizers consider all indexes on referenced tables uniformly, regardless of purpose, leading to suboptimal performance. The proposal aims to address this by making indexes sensitive to the context and origin of queries, improving optimization and response times for complex workloads on shared databases and schemas.
STORAGE GROWING FORECAST WITH BACULA BACKUP SOFTWARE CATALOG DATA MININGcsandit
Backup software information is a potential source for data mining: not only the unstructured
stored data from all other backed-up servers, but also backup jobs metadata, which is stored in
a formerly known catalog database. Data mining this database, in special, could be used in
order to improve backup quality, automation, reliability, predict bottlenecks, identify risks,
failure trends, and provide specific needed report information that could not be fetched from
closed format property stock property backup software database. Ignoring this data mining
project might be costly, with lots of unnecessary human intervention, uncoordinated work and
pitfalls, such as having backup service disruption, because of insufficient planning. The specific
goal of this practical paper is using Knowledge Discovery in Database Time Series, Stochastic
Models and R scripts in order to predict backup storage data growth. This project could not be
done with traditional closed format proprietary solutions, since it is generally impossible to
read their database data from third party software because of vendor lock-in deliberate
overshadow. Nevertheless, it is very feasible with Bacula: the current third most popular backup
software worldwide, and open source. This paper is focused on the backup storage demand
prediction problem, using the most popular prediction algorithms. Among them, Holt-Winters
Model had the highest success rate for the tested data sets.
An ontological approach to handle multidimensional schema evolution for data ...ijdms
In recent years, the number of digital information storage and retrieval systems has increased immensely.
Data warehousing has been found to be an extremely useful technology for integrating such heterogeneous
and autonomous information sources. Data within the data warehouse is modelled in the form of a star or
snowflake schema which facilitates business analysis in a multidimensional perspective. As user
requirements are interesting measures of business processes, the data warehouse schema is derived from
the information sources and business requirements. Due to the changing business scenario, the information
sources not only change their data, but also change their schema structure. In addition to the source
changes the business requirements for data warehouse may also change. Both these changes results in data
warehouse schema evolution. These changes can be handled either by just updating it in the DW model, or
can be developed as a new version of the DW structure. Existing approaches either deal with source
changes or requirements changes in a manual way and changes to the data warehouse schema is carried
out at the physical level. This may induce high maintenance costs and complex OLAP server
administration. As ontology seems to be a promising solution for the data warehouse research, in this
paper an ontological approach to automate the evolution of a data warehouse schema is proposed. This
method assists the data warehouse designer in handling evolution at the ontological level based on which
decision can be made to carry out the changes at the physical level. We evaluate the proposed ontological
approach with the existing method of manual adaptation of data warehouse schema.

This document provides information on a training module for understanding hydrological information system (HIS) concepts and setup. It includes an introduction to HIS, why they are needed, how they are set up under the Hydrology Project. It also discusses who the key users of hydrological data are and how computers are used in hydrological data processing. The training module contains session plans, presentations, handouts, and text to educate participants on HIS objectives, components, and how they provide reliable hydrological data to various end users.
This document provides information on setting up a Hydrological Information System (HIS) for India. It includes details on:
1. Defining key concepts of a HIS, including that it is a system to collect, process, and disseminate hydrological data to provide useful information to users.
2. The need for a standardized HIS in India to better plan for water resources given the variability of water patterns and inadequacies of existing systems.
3. The Hydrology Project aims to improve existing HIS across 8 Indian states to provide more reliable hydrological data for planning and management.
The document discusses technologies applied in distributed databases (DD) and distributed systems (DS). For DS, layered and client-server approaches are used to reduce complexity. The client-server model can be relational or object-oriented. For DD, important technologies are replication to synchronize data modification across nodes and duplication where a master data source copies content to other nodes. Technologies like client-server, object models, and NoSQL databases can be applied in both DD and DS.
Data Warehouses store integrated and consistent data in a subject-oriented data repository dedicated
especially to support business intelligence processes. However, keeping these repositories updated usually
involves complex and time-consuming processes, commonly denominated as Extract-Transform-Load tasks.
These data intensive tasks normally execute in a limited time window and their computational requirements
tend to grow in time as more data is dealt with. Therefore, we believe that a grid environment could suit
rather well as support for the backbone of the technical infrastructure with the clear financial advantage of
using already acquired desktop computers normally present in the organization. This article proposes a
different approach to deal with the distribution of ETL processes in a grid environment, taking into account
not only the processing performance of its nodes but also the existing bandwidth to estimate the grid
availability in a near future and therefore optimize workflow distribution.

Growth of relational model: Interdependence and complementary to big data IJECEIAES
A database management system is a constant application of science that provides a platform for the creation, movement, and use of voluminous data. The area has witnessed a series of developments and technological advancements from its conventional structured database to the recent buzzword, bigdata. This paper aims to provide a complete model of a relational database that is still being widely used because of its well known ACID properties namely, atomicity, consistency, integrity and durability. Specifically, the objective of this paper is to highlight the adoption of relational model approaches by bigdata techniques. Towards addressing the reason for this in corporation, this paper qualitatively studied the advancements done over a while on the relational data model. First, the variations in the data storage layout are illustrated based on the needs of the application. Second, quick data retrieval techniques like indexing, query processing and concurrency control methods are revealed. The paper provides vital insights to appraise the efficiency of the structured database in the unstructured environment, particularly when both consistency and scalability become an issue in the working of the hybrid transactional and analytical database management system.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

This document proposes context-sensitive indexes to optimize SQL query performance in multi-tenant and multi-application database environments. Current database architectures require indexes to be considered for all queries on a table, posing challenges for query optimization. The proposal is for applications and tenants to define their own indexes on shared tables to optimize their queries, while keeping indexes isolated from other applications and tenants for optimization purposes. The document provides background on challenges with mixed workloads and motivation for the proposal, which could lead to better optimized query processing and improved performance and scalability.
Temporal Database is the most convenient form to represent time element associated with data. Temporal validity support a unique feature of temporal database lets you associate one or more valid time dimensions with a table and have data be visible depending on its time-based validity, as determined by the start and end dates or time stamps of the period for which a given record is considered to be a valid record. This study focuses on checking and verification of temporal data using valid time dimension of temporal database. This study covers the steps for adding a valid time dimension on a table, and various methods for querying the table and retrieving records based on a specified valid time value or range with
help of Oracle 12c.
Management of Bi-Temporal Properties of Sql/Nosql Based Architectures – A Re...lyn kurian
Data engineering is the most important field in computer science engineering. Data is computed, stored and
manipulated according to the user requirement. Data can be text, picture, audio, video or document which is in various
formats. This paper deals with various database management systems that stores and manipulates data efficiently,
including banking system, scientific or commercial systems. Traditionally, we use RDBMS like MS SQL Server, IBM
DB2, Oracle, MySQL and Microsoft Access for transactional processing and analytical processing. On the advent of Big
Data, the strict RDBMS is not a customized solution on considering the performance and scalability aspects of the
Information Technology that needs today. The new era needs new technologies. Google introduced the concept of NoSQL
Databases in 2005, which led to the revolution of NoSQL databases like Noe4j, HBase, Redis, Mango DB etc. But
migration to NoSQL Databases is a challenging area for the database architects in various fields of business. Different
tools and techniques for database migration, query translation and query optimization is being adopted and the research
area is open. This paper comprises the categorization of the proposed and implemented bi-temporal databases along with
their bi-temporal properties till date.
Context-Sensitive Indexes for Performance Optimization of SQL Queries in Mult...Arjun Sirohi
This document discusses context-sensitive indexes in relational database management systems to optimize SQL query performance in multi-tenant and multi-application environments. It proposes allowing applications, tenants, and users to define their own indexes on shared database tables to optimize queries specific to them, while keeping these indexes isolated from other queries for optimization purposes. Currently, database optimizers consider all indexes on referenced tables uniformly, regardless of purpose, leading to suboptimal performance. The proposal aims to address this by making indexes sensitive to the context and origin of queries, improving optimization and response times for complex workloads on shared databases and schemas.
STORAGE GROWING FORECAST WITH BACULA BACKUP SOFTWARE CATALOG DATA MININGcsandit
Backup software information is a potential source for data mining: not only the unstructured
stored data from all other backed-up servers, but also backup jobs metadata, which is stored in
a formerly known catalog database. Data mining this database, in special, could be used in
order to improve backup quality, automation, reliability, predict bottlenecks, identify risks,
failure trends, and provide specific needed report information that could not be fetched from
closed format property stock property backup software database. Ignoring this data mining
project might be costly, with lots of unnecessary human intervention, uncoordinated work and
pitfalls, such as having backup service disruption, because of insufficient planning. The specific
goal of this practical paper is using Knowledge Discovery in Database Time Series, Stochastic
Models and R scripts in order to predict backup storage data growth. This project could not be
done with traditional closed format proprietary solutions, since it is generally impossible to
read their database data from third party software because of vendor lock-in deliberate
overshadow. Nevertheless, it is very feasible with Bacula: the current third most popular backup
software worldwide, and open source. This paper is focused on the backup storage demand
prediction problem, using the most popular prediction algorithms. Among them, Holt-Winters
Model had the highest success rate for the tested data sets.
An ontological approach to handle multidimensional schema evolution for data ...ijdms
In recent years, the number of digital information storage and retrieval systems has increased immensely.
Data warehousing has been found to be an extremely useful technology for integrating such heterogeneous
and autonomous information sources. Data within the data warehouse is modelled in the form of a star or
snowflake schema which facilitates business analysis in a multidimensional perspective. As user
requirements are interesting measures of business processes, the data warehouse schema is derived from
the information sources and business requirements. Due to the changing business scenario, the information
sources not only change their data, but also change their schema structure. In addition to the source
changes the business requirements for data warehouse may also change. Both these changes results in data
warehouse schema evolution. These changes can be handled either by just updating it in the DW model, or
can be developed as a new version of the DW structure. Existing approaches either deal with source
changes or requirements changes in a manual way and changes to the data warehouse schema is carried
out at the physical level. This may induce high maintenance costs and complex OLAP server
administration. As ontology seems to be a promising solution for the data warehouse research, in this
paper an ontological approach to automate the evolution of a data warehouse schema is proposed. This
method assists the data warehouse designer in handling evolution at the ontological level based on which
decision can be made to carry out the changes at the physical level. We evaluate the proposed ontological
approach with the existing method of manual adaptation of data warehouse schema.

The document discusses technologies applied in distributed databases (DD) and distributed systems (DS). For DS, layered and client-server approaches are used to reduce complexity. The client-server model can be relational or object-oriented. For DD, important technologies are replication to synchronize data modification across nodes and duplication where a master data source copies content to other nodes. Technologies like client-server, object models, and NoSQL databases can be applied in both DD and DS.
Data Warehouses store integrated and consistent data in a subject-oriented data repository dedicated
especially to support business intelligence processes. However, keeping these repositories updated usually
involves complex and time-consuming processes, commonly denominated as Extract-Transform-Load tasks.
These data intensive tasks normally execute in a limited time window and their computational requirements
tend to grow in time as more data is dealt with. Therefore, we believe that a grid environment could suit
rather well as support for the backbone of the technical infrastructure with the clear financial advantage of
using already acquired desktop computers normally present in the organization. This article proposes a
different approach to deal with the distribution of ETL processes in a grid environment, taking into account
not only the processing performance of its nodes but also the existing bandwidth to estimate the grid
availability in a near future and therefore optimize workflow distribution.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion

dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
