Datenbankverwaltung Jobs

My C# .NET solution used to run flawlessly, but after the last rebuild it dies on launch because the SQL Server connection string can no longer be resolved and several tables are either missing or never get created. I need you to: • inspect the current connection string in appsettings / , repair or replace it, and prove the app connects to the correct SQL Server instance; • trace the Entity Framework / Code-First (or raw SQL) migrations, make sure all expected tables and seed data exist, and clean up any drift; • explain briefly what went wrong so I can avoid the same pitfall at the next deployment. Once the project compiles and the app starts without errors, returning data from every affected table, I’ll consider the task complete. Feel free to work in Visua...

I’m running a live rubber-plant production system where SCADA writes every batch into SQL Server 2008. Actual weights and totals are perfect, yet the batch IDs that feed our SSRS reports appear twice at times or vanish altogether. These anomalies happen randomly; they are not linked to shift changes or load spikes. The job is a surgical fix. I do not want an audit or a redesign and there will be no PLC modifications or on-site work. All that is needed is to correct the existing SCADA script–to–SQL transaction logic so that one batch generated upstream produces one and only one row in the database, and every consecutive number is present. You’ll be working remotely on: • SCADA scripting (our environment supports WinCC, Wonderware, Ignition or Citect; bri...

I want a clean, interactive Power BI dashboard that lets me see, at a glance, how well my resources are being used across day-to-day operations. All underlying data sits in multiple Excel files, and I need the report to refresh smoothly whenever those spreadsheets are updated. If later I decide to connect an SQL database or a cloud source such as Azure, the model you build should be flexible enough to accommodate that without major re-work. Core focus • Resource utilization metrics: head-count allocation, machine/equipment uptime, capacity vs. demand, and any other utilisation KPIs you regularly deploy for similar projects. • Operational analytics views: trend lines, variance breakdowns, drill-through on cost centres or departments, and an overview page that surfaces the mos...

Looking for a developer to resolve a database issue on an ecommerce script, test it, and get the script to work properly.

I have several retrospective ICU studies underway and I need an analyst who already feels at home inside both MIMIC-III and MIMIC-IV on PhysioNet. The work centres on pulling raw tables, stitching them together through patient and hospital-stay identifiers, and transforming that sprawl into tidy, analysis-ready cohorts. Every step—from initial SQL queries to the last model diagnostic—must be reproducible and clinically defensible. Day to day you will: • Extract rows from the core Meds, diagnoses, procedures, labs, and vitals tables, then link them reliably across encounters. • Clean and preprocess the high-dimensional data, flagging implausible values and resolving unit or time-stamp issues. • Derive clinically meaningful variables (severity scores, medica...

Our production and staging workloads run on AWS Aurora Serverless MySQL, and the cluster now needs an expert hand to keep it lean, fast, and developer-friendly. Right away I need deep-dive database optimization, precise schema modifications, and continuous performance monitoring. You’ll work side-by-side with the backend team—reviewing pull requests, advising on best practices, and supplying migration scripts that fit cleanly into our CI/CD pipeline. Key goals • Tune queries, indexes, and cluster parameters so p99 latency stays consistently low. • Design and apply zero-downtime schema changes with rollback plans. • Stand up robust monitoring and alerting through Aurora Performance Insights, CloudWatch, and an open-source dashboard of your choice. Deliv...

I’m moving an existing Laravel application to a fresh VPS that already has cPanel. I have a complete copy of the project folder and a MySQL dump; the site must look and behave exactly the same as it does now—no redesigns, no feature tweaks. Here’s the work I need completed in one smooth session: • Upload every project file to the new server • Import the MySQL database and create the appropriate user • Configure the .env file so the app connects to the new database and mail settings correctly • Ensure the document root, permissions, and storage links are in place so the site loads on the temporary URL provided by the host • Once the temporary URL works flawlessly, guide me through updating the DNS so the live domain points to the new VPS ...

I want a clean, realtor-focused workspace inside that lets me capture every lead, follow each conversation, and keep my property inventory at hand without jumping between spreadsheets and inboxes. The build should include: • Lead management – a board that collects new inquiries (manual entry and embedded form), assigns them automatically, and moves them through custom statuses. • Client interaction tracking – a timeline of calls, emails, and meetings that links back to the original lead so I can see the full history in one click. • Property listings management – a central place for photos, specs, price changes, and availability, tied back to matching buyers. - internal integration for multiple boards to update. this is to start with an excel impor...

Overview We are a manufacturing company using Infor SyteLine (Cloud) and are seeking an experienced Infor SyteLine / Birst reporting developer to design and implement a daily, automated executive metrics report (“BBB”). This report is a single, consolidated PDF containing multiple operational, financial, and production metrics, distributed automatically to management. Note: This engagement is primarily for the BBB report described below.

Our database is exhibiting structural problems that trace back to the way its indexes were created and maintained. I need a specialist who can dig into the current schema, spot every faulty or missing index, and rebuild the structure so the tables relate cleanly and queries run as they should. You’ll start by auditing the existing schema and execution plans to confirm where index duplication, gaps, or bad selectivity are slowing things down. Once the weak points are mapped, I want a clear plan of action, then a set of scripts that create, drop, or rebuild the necessary indexes with minimal disruption to live traffic. After the changes are applied, please benchmark typical read- and write-heavy queries so we can validate the improvement before we push everything to production. Deliv...

Each week I receive batches of textual information that must be entered into an online database and then lightly formatted in companion documents. Your role is to take that raw text, follow my step-by-step template, and input it exactly where it belongs so the record set stays clean and searchable. Speed matters, but accuracy matters more. I double-check every field, so I need someone who types quickly yet never skips a review pass, catches typos, and confirms that every label, date, and reference number matches the source. Basic computer skills—copy-paste shortcuts, navigating drop-down menus, and simple formatting commands—are all that’s required; the complexity is in keeping the small details straight week after week. Communication is key. I’ll send the source ...

I’m spinning up a brand-new AWS environment and want it built right the first time. The core stack must include secure EC2 instances running a database server workload, S3 buckets for object storage, and at least one RDS database instance. This deployment will host banking-related data, so tight network segmentation, encryption at rest and in transit, and granular IAM policies are mandatory. My preference is to have everything created with infrastructure-as-code (CloudFormation or Terraform) to keep future changes controlled and auditable, but I’m open to your recommended tooling if it speeds delivery without sacrificing reliability. Deliverables • VPC design and implementation with public/private subnets, route tables, NAT, and security groups suitable for a production ...

My website – – is running on a cPanel-managed dedicated server that suffers from downtime, laggy performance and steadily climbing fees. I need the whole environment moved to a new host that is demonstrably more stable and offers better value without sacrificing speed. Here’s what I want to happen: • Analyse my current dedicated server setup and recommend one or two realistic alternatives that solve the downtime, cost and performance issues. Feel free to compare shared cloud plans, managed VPS or any other option you believe fits. • Prepare the new server (security hardening, PHP version, MySQL, SSL, email routing and any required modules) so it mirrors the existing stack. • Seamlessly migrate the site, databases, mail records and DNS with negligibl...

I’m building a solid prospecting base for my aviation-services business and need a structured dataset that lets me quickly understand both aircraft details and the repair stations that keep them airworthy. Here’s what I want to walk away with: a clean, up-to-date spreadsheet (or SQL/CSV if you prefer) that pairs aircraft information with nearby or commonly used repair stations. While I’m ultimately using the data to market my services, depth and accuracy matter more to me than sheer volume. Aircraft data • The essentials must include tail number, make/model, year, and current owner/operator. • Where easily obtainable, please add technical specs, last major maintenance events, and any publicly available maintenance tracking notes. Repair-station data ...

I need hands-on, day-to-day help from a seasoned DevOps Engineer to keep our AWS environment running smoothly while we roll out new features. The immediate focus is on three pillars: building a reliable CI/CD pipeline, codifying our infrastructure, and tightening monitoring and logging so issues surface before our users ever notice. We host everything in AWS, so you should feel at home with services such as CodePipeline, CodeBuild, CloudFormation or Terraform, ECS/EKS, CloudWatch, and any complementary tools you prefer (Jenkins, GitLab CI, Prometheus, Grafana, ELK, etc.). While DevOps work is priority one, experience touching data-engineering workflows or handling database administration will be an advantage as those needs crop up after the core automation is stable. Deliverables I&rsquo...

My WordPress site suddenly throws “Error establishing a database connection.” I have already double-checked the credentials and they are correct, yet the front-end and wp-admin remain inaccessible. The site sits on shared hosting, and I can log in to both the hosting control panel and SSH without restrictions. I need someone who can jump in, trace the root cause, and bring the site back online quickly. You will have full cPanel-style access, phpMyAdmin, and SSH to inspect MySQL service status, repair tables if needed, adjust server-side settings, or tweak WordPress core files. Once resolved, I’d appreciate a brief summary of what went wrong and any preventive steps I should take. Deliverable: the homepage and admin dashboard must load normally with no database connecti...

Urgent - support daily 2 hr maximum I’m looking for an Oracle E-Business Suite specialist who can move comfortably between the Financials stack, PL/SQL code, and SOA Suite web-service integrations. My environment is already live, but several custom packages need refactoring, new interfaces have to be exposed, and a few pain points in the Financials workflows call for expert attention. Day-to-day you’ll be reviewing existing PL/SQL, tightening performance where it lags, then wiring the results into Oracle SOA Suite services so external systems can consume or push data without manual intervention. The focus is on the Financials family—think General Ledger, Payables, Receivables, and related reporting—though I may ask you to touch other modules as the work unfolds. ...

My custom-built site has begun to drag: the home page hesitates, product pages crawl, and in truth every click feels sluggish. Tests point toward heavy database queries, but I’m open to any bottleneck you uncover. I need someone to profile the code and queries, trim what isn’t needed, and implement proven fixes—index tuning, query refactoring, smart caching, asset minification, or any other technique that will push the first meaningful paint and full page load comfortably below the two-second mark. Tools such as Lighthouse, GTmetrix, New Relic, or your preferred profiler are welcome so long as the before-and-after metrics are clear. When you’re finished, I want to see: • noticeably faster navigation between pages, • documented changes to the data...

I’m putting together a recruiting platform that connects NocoDB’s spreadsheet-style interface with a PostgreSQL ba. What I already have in mind • NocoDB will be the only front-end my recruiters see, so the tables, views and layouts have to feel as natural as a spreadsheet. • PostgreSQL is the single source of truth underneath it all; every field defined in NocoDB must map cleanly to a well-designed schema. • Core modules are Candidate management, Job requirement tracking and Client management. They should come pre-configured with sensible relationships, lookups and status pipelines so my team can hit the ground running. • Team members will start with read-only access. Granular role definitions and row-level security in both NocoDB and PostgreSQL mus...

This brief centres on drafting a solid, future-proof backend blueprint for a forthcoming digital health research platform. At this stage nothing will be built in code; the goal is to crystallise the architecture so Phase 2 developers can move straight into implementation with minimal guess-work. Scope The work spans high-level system design, an API structure outline, initial data models and an analytics flow concept. Core components to be addressed are: data storage and management, user authentication and authorisation, and data analytics/processing. Relational databases—specifically MySQL or PostgreSQL—should sit at the heart of the storage layer, while OAuth will anchor the authentication strategy. All diagrams and documentation must weave in security hardening and horizon...

I need experienced Power BI specialists for a four-week sprint focused on our hospital’s analytics stack. You’ll team up with me (the engineering manager) to design brand-new reports and tighten the data plumbing behind them. Here’s the landscape • Data source: Electronic Health Records flowing from our SQL-backed warehouse. • Targets: Resource management and clinical operations KPIs that our nursing leads review daily. • Core ask: create fresh, insight-rich visuals while improving the SQL queries and data model that feed them. Deliverables - At least three new Power BI dashboards, each centred on an agreed resource or clinical metric, ready for stakeholder sign-off. - Optimised SQL scripts and refreshed integration steps, documented and checked...

Bitte melde dich an oder Loge dich ein um Details zu sehen.

I’ve got a backlog of information that needs to be entered directly into my database and I simply don’t have the time to handle it myself. The task is straightforward: take the raw data I provide and create clean, well-structured records inside the existing system without introducing errors or duplicates. Consistency and attention to detail are critical because the data will be used for live reporting once the upload is complete. You’ll receive everything you need—the source files, field mapping notes, and login credentials—right after we agree on timing. All I ask is that each record is double-checked for accuracy before you hit save and that you keep a brief log of completed batches so I can track progress. If you’ve handled similar database data-ent...

I need an experienced Azure specialist to provision and configure a fresh Azure SQL Database for my current website code. Right now the site runs on a regular SQL Server instance; I’m unsure whether the existing data must be moved or recreated, so I’ll look to you for guidance on the most reliable path forward. The database’s role is straightforward—solid, fast data storage and retrieval for a live production app. You’ll handle the full setup inside the Azure portal, set the correct performance tier, secure it with firewall rules and proper authentication, generate the connection string, and make sure the site connects without hiccups. If we do identify an existing database worth migrating, you’ll take charge of exporting, importing, and validating the ...
