    Build HR Investigation Access Database
    6 ditë left
    Të verifikuara

    Our cloud-based HRIS serves us well for day-to-day data, yet it offers no space to document formal investigations. Right now each case is typed into a Word template and saved manually—a process that makes version control, trend analysis, and quick retrieval a chore. I need this entire workflow moved into Microsoft Access so every investigation sits in one secure, searchable place. The database must capture everything we currently record: employee details, an overall investigation summary, every witness statement or piece of evidence we collect, and the final resolution or outcome. On top of that core structure, I want automated notifications (for example, reminders when a case nears its deadline), robust reporting tools that let us pull both individual case summaries and aggregated ...

    I’m releasing a well-maintained database of Australian contacts that’s ready for call-centre, tele-sales or multi-channel lead-generation campaigns. The file combines both residential and commercial records so you can run B2C, B2B or blended outreach without hunting for separate lists. Residential segment – Every record carries the customer’s full name and direct contact details (phone and email wherever captured), plus suburb and postcode to make geographic targeting easy. Commercial segment – Contains core company contacts with the same direct fields. I’ll walk you through the exact columns once an NDA is signed. All entries were gathered and scrubbed during 2023-24, de-duplicated, and checked against our in-house Do-Not-Call suppression list. Ho...

    I quote jobs for drilling multiple holes into solid steel bars that range from 1.5 in to 12 in in diameter. Hole diameters vary from 0.75 in, 1 in, 1.5 in, 2 in, all the way up to 8 in, and a single bar can have any number of these holes spaced along its full length. Right now I juggle the numbers in a spreadsheet, but I need a faster, cleaner way. Please build the solution in FileMaker Pro. The calculator must let me choose the run size (bar diameter) and each branch size (hole diameter) from drop-down menus, enter the quantity of identical holes, and then return an instant price. The pricing logic is advanced: it has to consider the run size, every hole size, and the total number of holes, with the flexibility to factor in changes to material, labour, or machine rates later.

    Our custom construction ERP is in the final stretch. The core modules are in place, but three areas still block go-live: 1. Sales pipeline – Automation & workflows I have the UI and basic routes, yet deals do not progress automatically through stages, nor do the triggers for emails, task creation, and forecast updates fire reliably. I need you to hard-wire the logic in Node.js/Express and make sure the jQuery / Select2 front-end reflects every state change instantly. 2. PostgreSQL – Connection issues Under load the app occasionally drops connections and stalls. The schema relies on complex JOINs and several polymorphic associations, so I need a deep dive into pooling, transaction handling, and any rogue long-running queries that may starve connections.

    I need a compact module that connects to my SQL Server database, fetches raw attendance data, and delivers a clean report that mirrors the sample layout I will share. Two filters must work flawlessly and in combination: date-wise and employee-wise—both hold equal weight for daily use. Any duplicate rows you encounter should be excluded before the data reaches the final grid or export. My preference is an ASP.NET / C# backend, though you’re free to craft the stored procedures as you see fit. Once the dataset is shaped, the user should be able to export the report to both Excel and PDF with a single click, keeping the exact formatting intact (headers, column order, totals, page breaks).
