Sviluppo del Database Jobs

I have a rough system architecture sketch that urgently needs a polish so it clearly shows how our database layer can be tuned for better performance. The core of the exercise is to revisit the data flows, pinpoint latency hotspots, and illustrate an optimised structure—caching tiers, read/write segregation, indexing strategies—using a clean, professional diagram. You will start from my existing file (or import it into Lucidchart, Visio, or another tool you’re comfortable with) and reshape it into a concise, single-page system architecture diagram. The spotlight is entirely on the database component; server infrastructure and application logic can be represented at a high level only where they touch the data layer. Deliverables • Editable source file (, Lucidcha...

I need a complete pharmacy system that combines fast, accurate billing with a robust inventory back-end.

Inventory control must include: • Real-time stock updates the moment items are sold, returned, or received • Low-stock alerts triggered at thresholds I can set per SKU • Batch and expiry-date tracking so I always know what lots are nearing expiry and can pull reports by batch number The platform also has to talk to my existing tech stack. It should exchange data smoothly with: • Our Point of Sale system for front-counter transactions • The ERP system that handles purchasing and ...

I need a tailor-made ERP environment that lets me manage entire IT projects from the first line of the Bill of Quantity through to final hand-over, all inside a single database-driven workspace. The core of the build is a dedicated Project Management module tightly coupled with an advanced BOQ module. Within Project Management, every project record must automatically expose its own Bill of Quantity so I can drill down from high-level milestones to the finest component without leaving the screen. No other scheduling frills are required at this stage—accurate, real-time BOQ visibility is the priority. The BOQ module itself must allow me to: • Enter and maintain granular material cost estimates (hardware, cabling, licenses, etc.) • Track progress against each BOQ line so...

Each record must contain: borrower’s name, mobile number, pincode, total amount sanctioned, current outstanding balance, interest rate, EMI, and remaining tenure.

Feel free to tap verified channels such as financial institutions, real estate databases, and credit-bureau sources like CIBIL. I expect intermediate validation—so be sure every field follows a consistent format (numbers in the same units, phone numbers in the same pattern, etc.) be...

I have several production PL SQL scripts that are starting to show their age: execution times have crept up and they are consuming more CPU and memory than I am comfortable with. The primary focus of this project is therefore PLSQL itself, not application-level logic or UI work. What I need from you is a careful optimisation of the existing codebase. The goal is two-fold—raise overall performance and cut back on resource usage—without changing the functional output in any way. You will be working with code that is already in use, so a light-touch, incremental approach that can be verified against current results is essential. Deliverables I expect • Revised PL SQL scripts ready for drop-in replacement • A short before/after performance summary (timings and resourc...

I am looking to have a self-contained desktop application built that lets us record and track three key data sets in one place: staff information, individual training records, and detailed instrument-calibration histories. The program will be used on a small internal network, so a local database engine such as SQLite, MS Access, or an embedded PostgreSQL instance is perfectly acceptable as long as installation remains straightforward for non-technical users. Two role levels must be enforced: Admins need full create / update / delete privileges plus the ability to add new users, import legacy spreadsheets, and run global reports, while Managers only require read-only dashboards and the ability to print or export filtered reports for their teams. Typical daily tasks should feel intuitive: ...
