Datenbankprogrammierung Jobs

I’m running a web application on a custom-built PHP framework and it currently sits on an ageing database that I now want fully migrated to MySQL. The job is strictly a database migration—no codebase refactor is required at this stage—so the focus is on cleanly lifting all existing data structures and records into a fresh MySQL schema while keeping the application functional throughout the transition. What I’ll hand over: the current schema dump (or direct access if you prefer), sample data, and a brief outline of the application’s data flow so you can map dependencies accurately. What I expect back: • A MySQL-ready schema that mirrors the original structure, optimised where obvious gains are available (indexes, data types, constraints). • Reli...

Help wanted: daily/multi-daily comparison of supplier prices and stock levels (B2B webshop) Text: We operate a B2B webshop where business customers can place orders or commission items on request. Most of the goods are sourced directly from manufacturers. For most suppliers we have access to their stock levels and current prices; for some, no login is required, while others require login credentials. We are looking for a solution or a skilled professional who can help us retrieve supplier prices and stock levels daily — ideally multiple times per day — and compare them with our internal purchase prices so we stay up to date. No automatic syncing with our system or automatic price changes are required. It is sufficient if discrepancies between supplier prices and our system pu...

I need about three hours of guided, screen-shared help moving product data that currently lives in several related Excel sheets straight into my PostgreSQL database. No transformations are required—just a clean import exactly as the data sits now. During the session we will • create or confirm the target tables and column types, • choose the quickest import method (COPY commands, pgAdmin’s import wizard, or any tool you prefer), • load every sheet accurately, and • finish by writing a few SQL queries to verify row counts, join related tables, and pull sample SKU-level results. Deliverables for me at the end of the call will be: • a working, repeatable import script or step-by-step notes; • the example SELECT queries we ran together; a...

I’m standing up a brand-new business-intelligence stack in Snowflake and need a reusable migration framework built with dbt and solid SQL. The framework has to pull from two kinds of sources—existing relational databases and the steady stream of CSV/Excel flat files our teams export—then land, cleanse, validate, and automate each load all the way into analytics-ready tables. Here’s what I’m after: • A dbt project structured for easy extension, complete with models, seeds, macros, and tests that enforce data-quality rules at every stage. • Parameterised SQL and Snowflake tasks/procedures that orchestrate fully automated loads, from raw landing zones through staging to final marts. • Built-in monitoring and reporting—leveraging dbt tes...

I need help moving structured information that currently sits inside a batch of Word files into my SQL database. Every document follows the same template—think headings like Name, Address, Reference ID, Dates, and a few numeric fields—so once you see one you’ll immediately understand the layout of the rest. The job is pure data extraction from documents. You’ll read each Word file, pull the fields exactly as they appear, and insert them into the SQL tables I’ll provide. I will supply: • a sample of the Word template • the SQL schema with column descriptions • a small set of completed rows so you can confirm formatting Accuracy is key; any typos or misplaced values will create reporting issues downstream. Please make sure each entry match...

I am setting up a streamlined system that records and stores personal data only—no financial or operational information is involved. The core deliverable is a lightweight, well-structured database (MySQL, PostgreSQL, or similar) paired with a clean interface where I can input, edit, and search individual records with ease. Key expectations: • Design the data model to capture standard personal fields (name, address, phone, email, ID number), leaving it flexible for future additions. • Build a simple, password-protected web form or desktop utility for CRUD operations. • Include basic reporting so I can export selected records to CSV or PDF and view simple statistics such as total entries and date-range counts. • Provide clear setup instructions and brief user...

I need a brand-new Microsoft Access file that lets our small church keep all giving information in one place. The database should open with a simple membership form where I can manually add or update each giver’s name, address and contact details. Every giver must have a unique ID so that offerings entered later will always link back to the correct person. A second form will record each offering. When I choose the member’s name, the form should automatically pull in their ID; I then select the fund from a drop-down list that starts with Tithe, Building Fund, Missions, Mercy Ministries and Other. I also need the option to add new fund names on the fly without touching the table design, plus a memo area for special notes. From these two tables I want to run three practical repo...

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...

Project Overview We have an existing Microsoft Access [Year2019/ 365] application currently split into a front-end and back-end. We need to migrate the back-end data to SQL Server Express to improve stability and multi-user performance. The front-end must remain in Access and be optimized to work efficiently with the new SQL back-end. Key Tasks & Responsibilities Database Migration: Upsize all tables from the Access .accdb/.mdb file to a SQL Server Express instance. Data Integrity: Ensure all primary keys, foreign keys, and relationships are correctly mapped and enforced in SQL Server. Table Linking: Use ODBC to link the Access front-end to the new SQL Server tables. Query Optimization: Identify and convert "heavy" Access queries into SQL Server Views or Stored Procedures...

I have an Access database for managing information about friends and relatives. I use this to automatically address snail mail for birthday cards & Christmas letters etc., generate monthly birthday lists, record gifts given, and various other things. It is not a particularly good design but it serves my purposes. I have developed a few queries to create address labels in various formats. The queries work fine for couples but it gets a bit tricky to NOT include a partner if they have passed on or separated etc. It is tricky because I want to keep the information about everybody even after they have passed, but I don't want to include their name when addressing a card or letter to the remaining partner. I would rather not re-write the database and am looking for someone to creat...

We have an MS Access application (connected to MS SQL Server) that has been developed over the last 8 years. We need an MS Access developer to add features and fix errors. It is used for reporting (predefined filters on tables), sending emails, generting printouts and recording data that our ERP is not flexible enough to accept. The application needs improvements in database design (table normalisation, indexes), bug fixes, removing dead code/reports/forms and adding new features.

Manejo diariamente grandes volúmenes de consultas de clientes; registro cada caso y luego lo sigo hasta su resolución. Para ello utilizo hojas de cálculo y una base de datos sencilla, pero el acceso se ha vuelto lento y está afectando mi productividad y la calidad del soporte que doy. Quiero que un especialista revise la estructura actual, identifique los cuellos de botella y diseñe una solución que acelere la búsqueda, carga y actualización de la información. No importa si la propuesta implica depurar las hojas de cálculo, normalizar tablas SQL, automatizar procesos con scripts o incluso migrar a otro motor: lo esencial es reducir drásticamente los tiempos de respuesta sin perder la trazabilidad de cada ticket d...
