By keeping the data in check, it makes it easier to manage. But here's a quick reminder - the code that is used to build the database is super important too! In this week's DB edition, we will discuss how to optimize, code, and manage databases effectively. Key Highlights: - [Using the psql query and scripting tool]( - [ChatGPT and PowerShell – Some practical examples]( - [Deploy a Serverless Data Processing Solution With DynamoDB]( If you are interested in sharing ideas to foster the growth of the professional data community, then this survey is for you. Consider it as your space to share your thoughts! Jump on in! [TELL US WHAT YOU THINK]( Cheers, Merlyn Shelley Editor in Chief, Packt Latest Forks on GitHub - [blazegraph]( Blazegraph™ DB is an ultra high-performance graph database supporting Blueprints and RDF/SPARQL APIs. - [nette]( A database layer with a familiar PDO-like API but much more powerful. - [dbeaver]( Free multi-platform database tool that supports any database which has JDBC driver. - [typeorm]( TypeORM supports both [Active Record]( and [Data Mapper]( patterns, unlike all other JavaScript ORMs. - [dgraph-io]( Dgraph is a horizontally scalable and distributed GraphQL database with a graph backend. - [surrealdb]( A scalable, distributed, collaborative, document-graph database, for the realtime web. - [arangodb]( A native multi-model database with flexible data models for documents, graphs, and key-values.

However, managing OSS Redis can be tedious. Moving to managed [Amazon ElastiCache for Redis]( eliminates the administrative tasks associated with self-managed OSS Redis, including monitoring, patching, backups, and automatic failover. Microsoft Graph [[Code Sample] Microsoft Graph delta query sample:]( This project has adopted the [Microsoft Open Source Code of Conduct.]( The console application that the project has developed demonstrates how to use [delta queries]( in Microsoft Graph. Delta queries allow applications to request only the entities that have been updated or added since the last request. This can significantly reduce the amount of data that needs to be transferred and processed by the application, improving performance and scalability. MongoDB [[Visualize] Your MongoDB Atlas Data with Atlas Charts:]( [Atlas Charts]( is MongoDB's data visualization tool built natively into MongoDB Atlas. It allows users to gain insights and take action based on key data such as sales, operations, and product usage. Being the only native data visualization tool for the document model, it is the quickest and easiest way to visualize data from Atlas. Just for Laughs! Why do graph databases make great detectives? They're really good at finding connections! Quick DB Practice [Using the psql query and scripting tool]( - By [Simon Riggs]( [Gianni Ciolli]( psql is the query tool supplied as a part of the core distribution of PostgreSQL, so it is available in all environments and works similarly in all of them. This makes it an ideal choice for developing portable applications and techniques. psql provides features for use as both an interactive query tool and as a scripting tool. Getting ready From here on, we will assume that the psql command is enough to allow you access to the PostgreSQL server. This assumes that all your connection parameters are defaults, which may not be true. Written in full, the connection parameters will be either of these options: psql -h myhost -p 5432 -d mydb -U myuser psql postgresql://myuser@myhost:5432/mydb The default value for the port (-p) is 5432. By default, mydb and myuser are both identical to the operating system’s username. The default myhost on Windows is localhost, while on Unix, we use the default directory for Unix socket connections. The location of such directories varies across distributions and is set at compile time. How to do it… The command that executes a single SQL command and prints the output is the easiest, as shown here: $ psql -c "SELECT current_time" timetz ----------------- 18:48:32.484+01 To learn more about the process, head over to the book, [PostgreSQL 14 Administration Cookbook (packtpub.com).]( [SIT BACK, RELAX & START READING!]( Find Out What’s New? - [[Tutorial] Use AWS Controllers for Kubernetes To Deploy a Serverless Data Processing Solution With SQS, Lambda, and DynamoDB:]( Learn how to use [AWS Controllers for Kubernetes]( to create a Lambda function, SQS, and DynamoDB table and deploy a solution on an Amazon EKS cluster. This involves processing data from an [SQS queue]( using [Lambda]( and saving it to a [DynamoDB]( table. - [[Manage] XML Files with Apache Spark:]( Azure Databricks provides big data engineers with a [library]( to work with XML files, and Spark offers syntax to read XML files into a dataframe or manage them as a hive table. It's best to supply the file schema for performance, and reading XML files with multiple record types may require multiple reads. - [[Compare] Proxies for MySQL:]( When selecting a proxy solution for an architecture, factors like location, connection redirection, caching, and filtering must be considered. For Kubernetes and Operators, resource optimization is crucial, and HAProxy is considered the best option due to its efficiency. - [[Webinar] Exploring the Modern DBA:]( The webinar "[The Role of the DBA in 2023: Changes, Challenges, and Opportunities]( discussed how DBAs can overcome challenges in an ever-evolving enterprise database environment. Here, the experts highlighted methods and strategies to manage the increasing data generation, new data types and applications, and rising databases. - [[Generate Code] ChatGPT and PowerShell – Some practical examples:]( This article will demonstrate the integration of PowerShell and ChatGPT. [Practical examples in T-SQL]( specifically in SQL Server, are also explained here. PowerShell, a command-line shell for automation and tool integration, will be used alongside ChatGPT and SQL Server. - [[New functions] in SQL Server 2022 - BIT_COUNT, GET_BIT and SET_BIT:]( BIT_COUNT, GET_BIT, AND SET_BIT are new functions in the SQL Server 2022 that allow you to check and update binary data. This article explores the methods to include these new functions in your project scenarios and demonstrates how they can be beneficial. Happy learning!
