    I need a Windows-based desktop program that follows each sofa, chair, or table we build from the moment it is sold right through to the truck leaving our dock. The flow should start with order entry, automatically raise the fabric purchase request, then guide the piece through cutting, frame-building, upholstery, packaging, and finally shipping. At every stage I want a clear status board and simple way to update progress so the whole team can see what is waiting, what is in work, and what is finished. A small local SQL database is fine as long as it scales to a few dozen simultaneous users; if you prefer another lightweight option, mention it and why. The interface must be straightforward—touch-friendly for the shop floor, keyboard-driven in the office—so staff can scan a barc...

    Magento Reindex Product Price Fix

    Our Magento 2 store suddenly refuses to complete the Product Price reindex and shows the familiar “no linked stock” message. Nothing was updated, no extensions were added, and I haven’t tried any quick-fix SQL scripts or CLI commands yet, so you’ll be starting with a clean slate. I’m looking for someone who has already wrestled with this specific indexing glitch and can get the catalog back to a fully reindexed state without disrupting live traffic. Acceptance criteria / deliverables: • Identify the root cause of the “product price index – no linked stock” error and document it briefly. • Apply the corrective fix (database clean-up, configuration adjustment, or code patch) on our staging site, demonstrate a successful bin/magent...

    My goal is to turn a messy collection of raw files into a clean, analysis-ready dataset hosted on Google Cloud so I can make faster, well-informed decisions. The data first needs three specific text-cleaning steps—removing duplicates, correcting typos, and standardising formats. Once those tasks are automated, the cleaned output should flow straight into a Google Cloud environment (BigQuery is ideal, but Cloud Storage plus Cloud Functions works too). After the upload, I want an exploratory analysis that highlights patterns, trends and any obvious outliers that deserve attention. Deliverables • Well-commented scripts or workflows that automate duplicate removal, spell-checking and format standardisation • A repeatable pipeline that loads the cleansed data into Google C...

Deliverables • An Excel file where each dataset appears as a properly labeled table, with field names matching Tally, dates and numbers intact, ready for analysis or import elsewhere. We will provide Tally data file. Let me know which approach you prefer (TDL, ODBC, etc.) and how quickly you can turn the finished workbook around. Please also advise your working days and hours.

    It is my college final year project Basis. This project focuses on the design and implementation of a distributed NoSQL database system capable of handling large-scale, dynamic data with high availability, scalability, and strong consistency. The system uses dynamic sharding to automatically partition and distribute data across multiple nodes based on data growth and access patterns. It incorporates replication and consistency mechanisms such as quorum-based replication or distributed consensus protocols to ensure data integrity even during node failures or network partitions. The project aims to balance the scalability and flexibility of NoSQL systems with the consistency guarantees of traditional databases. Performance, scalability, and consistency are evaluated under different worklo...

    I’m looking for a reliable way to mirror my on-premise SQL database to AWS RDS in real time.

    I am completing a capstone project that must showcase end-to-end work inside Power BI. The source data sits in SQL Server and is modest in size—well under 10 k rows—so performance tuning will centre on clean Query Folding rather than heavy aggregation tricks. Here is what I need done: • Connect Power BI to the SQL Server instance through Power Query, document each step, and keep every transformation foldable. • Shape and load the tables, then model them with the correct many-to-many relationship where required. Please do this in the Model view so the links are visually clear. • Create essential DAX measures—CALCULATE(), RELATED(), and any supporting columns you find helpful—so the model answers typical summary and slice-and-dice questions. &bu...

    I want to move beyond day-to-day administration and master the advanced stack of Oracle Database technologies through live online sessions. The trainer I am looking for should be an experienced Oracle DBA who can walk me through real-world scenarios, share best practices drawn from production work, and guide me as I practice each topic in my own lab. The areas I need covered are very specific: Performance Tuning, Backup & Recovery (RMAN), Data Guard, RAC, GoldenGate, ASM, and end-to-end migration, Mock interviews and upgrade strategies. Every concept should be backed by live demonstrations, scripts I can reuse, and practical troubleshooting tips. Because I learn best in an interactive setting, I prefer a schedule of live classes where I can ask questions on the spot and share my scre...

    During statement-level regression testing I noticed that any policy carrying a premium tax—examples 01N6000098 and 600000000000809—now shows the wrong death benefit on the client statement. The PDF is pulling DEATH BENEFIT VALUE, yet it should reference TOTAL DEATH BENE VAL on Valm D. I need someone experienced with our policy management system’s data layer, statement generation logic (SQL extracts, mapping tables, Jasper / Crystal templates—whatever tool you prefer to work in), and general insurance data structures to: • Trace the field mapping used when the statement compiles. • Update or override it so the statement fetches TOTAL DEATH BENE VAL for any policy where a premium tax flag exists. • Regression-test at least the two sample policies ...

    I need an experienced Workday integration consultant to plug reliable data into the HCM (sometimes called “HMM”) module so we can finally unlock the rich reporting features we’re paying for. The sole objective is to enhance reporting capabilities—no broader HR process overhaul for now, just crisp, automated data flows that feed powerful, real-time reports. Here’s how I see the engagement unfolding: • Assess the current data landscape, spotting gaps or redundancies that prevent us from building accurate reports. • Design and build integrations—EIB, Workday Studio, Workday Prism Analytics, or another tool you recommend—that funnel clean data into Workday tables used by Workday Report Writer. • Configure calculated fields and cust...

    I need the full set of customer-related records lifted from my SQL database and dropped into a single worksheet that follows a template I’ll send you. The database holds tables for customers, payments, customer relations, sales and units. Your job is to write the necessary SQL (views, joins or stored procedures—whatever is most efficient), run it, and populate the template with: • each customer’s name and contact details • their complete purchase history and account status • the matching payment, sales and unit information Everything must end up in one sheet exactly where the template expects it, so column order and data types have to match. Once the file is filled, deliver it back together with the extraction script or query so I can repeat the proce...

    I’m looking for an experienced Oracle professional who can both teach and advise on PMI-aligned best practices. The engagement covers two fronts: first, delivering clear, hands-on sessions that walk my team through Oracle concepts mapped to the PMI framework; second, helping us design and fine-tune a practical lab so participants can experiment safely with the same features you demonstrate. Dates are flexible and the commercial terms can be shaped around your availability. I’m open to trainers, consultants, or architects—as long as you have a proven record teaching Oracle in a project-management context and can back it up with real-world examples.
