    I need my Open Journal Systems instance taken from version 3.3 to 3.5.0.3. Alongside the version bump I would like a few fresh interface touches—think new blocks, buttons or info panels that help editors access key tools faster. Existing workflows and plugins can stay as they are as long as the upgrade itself runs smoothly; small visual shifts are welcome if they come with the new elements we add. Here is what I have in mind: • Full files-and-database backup before you touch anything. • Clean upgrade to 3.5.0.3 with all standard post-upgrade checks (DB migrations, plugin compatibility, email templates). • Final verification that submission, review and publishing still work end-to-end.

    I have a set of records that must be keyed directly into our Microsoft SQL Server database. Everything needs to be done by hand—no automated import tools—so each field is checked for accuracy as it goes in. Here is how the work will flow: • I supply the table schema, any lookup lists, and clear formatting rules. • You receive the source files and a secure connection to the database. • As you enter each record, you verify mandatory fields, follow the naming conventions, and flag anything that does not align with the guidelines. • When the batch is complete, you run a quick count against my control totals so we know everything landed where it should. The goal is simple: a clean, fully populated SQL Server table with zero duplicates and no missing...

    I need to bring several Visual FoxPro databases up to modern standards while also building a fresh one from scratch. On the legacy side, the structure needs a careful redesign so tables, indexes, and relations make sense for today’s workflows. As part of that redesign, stale and duplicate records have to be cleansed, and performance tuned so queries return instantly rather than in minutes. Once the data is sound, I want clear, professional-looking reports and analytics dashboards that management can run with a single click. The new database should follow the same architecture and optimisation principles so it integrates cleanly with our existing codebase. Everything must stay native to Visual FoxPro; however, if a lightweight helper tool (e.g., SQL Server Express or Power BI for t...

    I need a seasoned Tally user to build a complete book of accounts focused on inventory management and to configure the system so I can pull accurate financial reports any time I need them. The company file has to be set up from scratch in Tally (ERP 9 or Prime), with every stock item, godown, and unit of measure properly mapped to the chart of accounts. What has to happen: • Create the inventory-centric ledger structure, enter opening balances, and enable stock tracking features. • Configure voucher types, taxation ledgers, and cost centres so that monthly profit-and-loss, balance-sheet, and stock-summary reports generate correctly without extra adjustments. • Provide a brief hand-over guide and one remote walkthrough so I know exactly how to enter day-to-day inventor...

    I have a backlog of financial figures that must be transferred accurately into working spreadsheets and then reflected in our existing SQL database. The spreadsheets will be the primary source, so precision in every cell—dates, currency formats, formulas, and cross-sheet references—is essential before the data is pushed to the database. You will receive scanned source documents, the current Excel template, and credentials to a staging schema in our SQL environment. Once each spreadsheet is complete and vetted for errors, the corresponding tables in SQL need to be updated so that our reporting dashboards stay in sync. Deliverables • Completed Excel workbook with all financial data correctly entered and formatted • SQL script (or direct upload) that mirrors the sp...

    I need a techno-functional specialist who knows SAP HANA inside-out to set up an automated pipeline that pulls data from three live modules—Financial (FI), Production Planning (PP) and Plant Maintenance (PM)—and ships it to a remote server on a fixed schedule. Here is what I am after: • Build or configure the job inside HANA Server (HANA DB with query language access, or any proven method you recommend... No additional connector licenses will be bought) so that it extracts the required tables and views, converts the output to clean JSON and pushes it to the destination path via SFTP or a comparable secure protocol. • The transfer must run on a schedule that I can adjust easily (hourly, daily thrice weekly, etc.) without redeploying code. Preferably leave the cr...

    I need an API layer that lets HikCentral Pro push employee attendance records directly into my SQL database. HikCentral will be the data source; the SQL instance will act as the system of record. At the moment I’m not completely sure of the payload format—HikCentral’s documentation mentions something that looks like “POSTSQL”, so I’ll need guidance on the exact structure (it could end up as JSON once we see the sample webhook). Core requirements • Accept incoming attendance records from HikCentral over HTTPS. • Route those records into a chosen table within my SQL environment (SQL Server is currently installed, but I can adjust if you suggest a better flavour). • Support three actions through separate, secure endpoints or a single e...

    (Solo perfiles con experiencia demostrable en diseño de esquemas PostgreSQL en producción. No busco desarrollo web, sino arquitectura y consistencia relacional.) Tengo una base de datos PostgreSQL alojada en Supabase que recoge partidos, goles, tarjetas, convocatorias, sustituciones y más.
