Database Administration Jobs

I have a batch of paper forms—mostly invoices and order sheets—containing thousands of numeric fields that must be transferred directly into our client-facing database. You’ll be working from high-resolution scans that I’ll supply in PDF format. Each document follows the same layout, so once you understand the field order the process is straightforward, but absolute accuracy is critical; even a single misplaced digit can throw off our reporting. You’ll receive: • A folder of the scanned documents • A web login to the database interface with clear field labels and example entries • A short style guide that explains how to handle illegible characters, missing values, and verification steps Your job is to key every numeric value from the ...

We are a recruiting and staffing firm finishing a move from Bullhorn to Crelate. We have Bullhorn's final full database backup (SQL Server 2022, encrypted, about 1.8 GB) and need an experienced SQL Server person to restore it, extract specific data, match it to our existing records, and import it into our Crelate account. WHAT YOU WILL DO 1. Restore the encrypted backup on your own SQL Server instance and confirm it opens. 2. Send us record counts for contacts, companies, jobs, and notes/activities. 3. Export contacts with their email addresses and phone numbers, and export contact notes with the original author and date. 4. Match Bullhorn contacts to our existing Crelate contacts (email first, then name plus company) and create import-ready files that fill only blank emails and phon...

I have a single 105 GB Oracle Data Pump backup (.dmp). Using only the regular database account that came with the file (no system or admin user) I want to expose about twenty-five specific tables through a simple web interface and run it on my Windows server. The solution has to be written in ASP.NET Core MVC with or a comparable Oracle driver so I can extend it later. For now the interface only needs to display the data: clean grid, quick pagination, optional column sorting—no editing required at this stage. Because I am uncertain of the dump’s original Oracle version, part of the work will be getting the file imported or otherwise made readable under a current Oracle installation without requiring SYS privileges. I will provide: • the .dmp file, • the user na...

I need our database layer re-designed so that records load faster and more reliably through the web application. The focus is squarely on improving data accessibility: queries must return results quickly, and common user actions should no longer be blocked by heavy reads or locking issues. Work begins with an audit of the current schema, index usage, and query patterns. From there, produce an optimized structure, add or adjust indexing, and recommend any caching or sharding techniques that match the projected growth of our data set. Wherever possible, keep the solution portable across standard relational engines (PostgreSQL or MySQL are most relevant right now) and cloud hosting environments. Acceptance criteria • Revised schema and index scripts in executable SQL. • A concis...

I’m putting together a fundamentals-level SQL program for an international group of beginners and I need an instructor who has real-world experience writing queries day-to-day. The goal is to walk participants through core concepts—tables, SELECT statements, WHERE, JOIN, GROUP BY, simple subqueries—so they leave confident enough to explore data on their own. All sessions will be delivered live online in English, so you should be comfortable presenting over Zoom or a similar platform, fielding questions on the spot, and adapting your pace if the group needs extra clarification. I will handle scheduling and participant logistics; you bring engaging explanations, clear slides, and practical demos that work on any standard SQL engine (MySQL, PostgreSQL, SQL Server, or SQLite...

I need an SSRS specialist to create production-ready tabular reports that pull live data from our SQL Server database. You will work from an existing schema, write or refine the underlying T-SQL, and build clear, parameter-driven layouts that can be deployed straight to our Reporting Services instance. Key deliverables: • RDL files for each finished report • Associated SQL scripts or stored procedures • Brief deployment notes and usage documentation Each report must render quickly, show accurate aggregates, and respect our existing security model once published to the server. If you have solid experience with SQL Server Reporting Services and enjoy turning raw tables into clean, consumable output, let’s get started.

Developed a Pharmacy Management System using SQL to design and build a relational database for managing essential pharmacy operations and data. The project includes tables for Suppliers, Drug Categories, Medicines, Pharmacists, Invoices, and Invoice Details, with properly defined Primary Keys, Foreign Keys, and relationships between tables. Implemented data insertion, retrieval, filtering, sorting, and modification using SQL queries, including Aggregate Functions, GROUP BY, JOINs, and Subqueries, as well as INSERT, UPDATE, and DELETE operations. Technologies: SQL Server, Database Design, Relational Databases, SQL Queries.

I need a specialist who can wire several production-level databases together so that information flows in real time, is captured accurately, and remains easy to trace long after it lands in storage. The job starts with building the live integration layer: connections, transforms, and routing must update immediately as changes occur in the source databases (no batch or nightly jobs). Once the stream is flowing, I want a solid verification routine to run alongside it. Data consistency checks should flag mismatches, duplicates, or missing fields the moment they appear, then write clear exception logs I can review. This audit trail will be the backbone of weekly compliance reviews. All incoming files—whether produced by the integration or uploaded manually—should sit in an organi...

I maintain several live databases that generate a steady stream of purely numerical records—transaction totals, sensor readings, and performance metrics. The raw pulls already sit in secure tables; what I need now is a sharp pair of eyes (and ideally a few smart scripts) to make sure every figure is trustworthy before it feeds our reporting pipeline. Your focus will be end-to-end validation rather than manual typing. You’ll connect to the databases remotely, run consistency checks, flag outliers, trace discrepancies back to source tables, and document any corrections you make. If you prefer working in SQL, Python (pandas), or even a robust Excel environment linked through ODBC, that is perfect; the key is delivering a clean, fully audited dataset that reconciles against the or...

My application suddenly stopped reaching its underlying database and any direct connection attempt times out or throws generic “unable to access database” errors. Credentials have not changed and the server process appears to be running, so I suspect something deeper—possibly configuration, permission conflicts, or corruption—but I need fresh eyes to pinpoint and resolve it quickly. You will start by investigating the connection path end-to-end, identify the exact obstacle, then apply the safest fix to restore full read/write access without data loss. Please document the steps you take and any changes you make so I can keep the system stable going forward. To jump in, let me know which diagnostic checks you would run first and any information you need from me (log...

I’m expanding a key e-commerce account and need a reliable virtual assistant who can keep our daily operations running smoothly. Your core focus will be three things: clearing and prioritising the shared inbox, locking in appointments across time zones, and giving prompt, friendly customer support that matches our store’s tone. Because this is a fast-moving online retail environment, I value someone already familiar with common storefront dashboards and order-management flows. You should feel at home inside Gmail or Outlook, be comfortable jumping into Slack or Teams chats when needed, and hop on Zoom for the occasional face-to-face check-in. Deliverables I’ll look for each day: • Inbox zero with urgent messages flagged and answered • A clean, updated calend...
