  • Resource description framework query language

    The query languages such as SPARQL which are used to retrieve and manipulate data stored in Resource Description Framework format (RDF).

  • Database development tools

    The methodologies and tools used for creating logical and physical structure of databases, such as logical data structures, diagrams, modelling methodologies and entity-relationships.

  • Data quality assessment

    The process of revealing data issues using ​quality indicators, measures and metrics in order to plan data cleansing and data enrichment strategies according to data quality criteria.

  • Query languages

    The field of standardised computer languages for retrieval of information from a database and of documents containing the needed information.

  • Database management systems

    The tools for creating, updating and managing databases, such as Oracle, MySQL and Microsoft SQL Server.

    The physical and technical concepts of how digital data storage is organised in specific schemes both locally, such as hard-drives and random-access memories (RAM) and remotely, via network, internet or cloud.

Skills

  • Perform backups

    Implement backup procedures to backup data and systems to ensure permanent and reliable system operation. Execute data backups in order to secure information by copying and archiving to ensure integrity during system integration and after data loss occurrence.

  • Maintain database performance

    Calculate values for database parameters. Implement new releases and execute regular maintenance tasks such as establishing backup strategies and eliminating index fragmentation. Evaluate hardware products and operating systems.

  • Balance database resources

    Stabilise the workload and resources of a database, by controlling the demand of transactions, allocating disk spaces and ensuring reliability of the servers in order to optimise cost and risk ratio.

  • Define database physical structure

    Specify the physical configuration of database files on a given media. This consists of in-detail specifications of indexing options, data types and data elements placed in the data dictionary.

  • Interpret technical texts

    Read and understand technical texts that provide information on how to perform a task, usually explained in steps.

  • Operate relational database management system

    Extract, store and verify information using database management systems based on the relational database model, which arranges data into tables of rows and columns, such as Oracle Database, Microsoft SQL Server and MySQL (Oracle Corporation).

  • Maintain database security

    Master a wide variety of information security controls in order to pursue maximal database protection.

  • Create data models

    Use specific techniques and methodologies to analyse the data requirements of an organisation's business processes in order to create models for these data, such as conceptual, logical and physical models. These models have a specific structure and format.

  • Design database backup specifications

    Specify procedures to be performed on databases which ensure the copying and archiving of data for possible restoration in case of a data loss event.

  • Administer ICT system

    Handle components of ICT system by maintaining configuration, managing users, monitoring resource use, performing backups and installing hardware or software in order to ensure that the system meets the set requirements.

  • Perform ICT troubleshooting

    Identify problems with servers, desktops, printers, networks, and remote access, and perform actions which solve the problems.

  • Design database scheme

    Draft a database scheme by following the Relational Database Management System (RDBMS) rules in order to create a logically arranged group of objects such as tables, columns and processes.

  • Apply company policies

    Apply the principles and rules that govern the activities and processes of an organisation.

  • Use scripting programming

    Utilise specialised ICT tools to create computer code that is interpreted by the corresponding run-time environments in order to extend applications and automate common computer operations. Use programming languages which support this method such as Unix Shell scripts, JavaScript, Python and Ruby.

  • Manage database

    Apply database design schemes and models, define data dependencies, use query languages and database management systems (DBMS) to develop and manage databases.
