Data Management involves the practices, architectural techniques, and tools for achieving consistent access to and delivery of data across the spectrum of data subject areas and data structure types in the enterprise, to meet the data consumption requirements of all applications and business processes.
Domain | Role of Data Management |
Healthcare | Manage patient records effectively |
Finance | Track transactions and client data |
Education | Manage student records and academic data |
For example, without effective data management, a healthcare facility may not be able to quickly access a patient's medical records, which could compromise the patient's care, increase liability issues, or decrease patient satisfaction and trust.
One interesting application of data management in engineering is in the field of computer-aided engineering (CAE), where engineers use precise data to simulate, validate, and optimize designs early in the product development lifecycle.
Data Management in Civil Engineering: In civil engineering, data management is crucial in maintaining safety standards and efficiency. For instance, during the construction of a building, engineers accumulate extensive data such as soil reports, weather conditions, structural designs, and material strengths. Correct handling and analysis of these data types help in construction decision-making and avoiding potential life-threatening hazards.
Data Management in Software Engineering: In software engineering, efficient data management is at the core of creating robust and reliable software. Databases used in software applications are required to manage vast amounts of data. Engineers need to create data models, handle data scaling, implement security measures, and assure data integrity while developing these databases. Incorrect data handling or data breaches can lead to catastrophic results, including loss of revenue, trust, and reputation for businesses.
Data Management in Industrial Engineering: In Industrial Engineering, effective data management plays a key role in maintaining equipment, tracking inventory, and managing the supply chain. Data from sensors and machines, when properly curated and analysed, helps increase productivity, avoid equipment failure, and predict potential operational issues. Poor data management could result in increased downtime, wastage of resources, and lower profitability.
The Boeing 787 Dreamliner: A renowned example of effective data management in engineering comes from the aerospace industry - Boeing's 787 Dreamliner. The aircraft has over 6,000,000 parts sourced from different locations worldwide. Managing such a complex and vast network of components posed a massive challenge. Boeing, however, used a data-centric system, the Digital Preassembly, that maintained all product and process data in a central repository. This approach enabled numerous participants in the project to access real-time data, which significantly improved decision-making, efficiency and reduced the chances of errors. It's an excellent instance of how good data management practice can be a game-changer.
Load Data: This involves recording the amount of power drawn by different components of the system at different times. Pattern analysis of this load data can help in predictive maintenance and system upgrades.
For example, life cycle assessment of a car would require data on the carbon footprint of extracting iron ore for making steel, the energy consumed by the engine during the operational life of the car, and the environmental impact of disposing of or recycling the car at the end of its use.
such as: def db_insert(name, email, pwd): insert_into table users values (name, email, pwd)Whether requested data can be fetched quickly, whether relationships between different data can be established, and whether the data recovery process is efficient in case of a system crash - these are all topics of data management in software engineering.
Relational Database: A database structured to recognize relations between stored items of information. NoSQL Database: A non-relational DMS, that allows for high-performance, agile processing of information at massive scale. It's used in large-scale applications development in big data and real-time web apps. Data Warehouse: A large store of data collected from a wide range of sources within a company and used to guide management decisions.
Database Management Systems (DBMS): Provide a structured method to store, manage, and retrieve data. The data can be queried, sorted, and manipulated efficiently using SQL (Structured Query Language). Common examples include Oracle, MySQL and Microsoft SQL Server.
Data Warehousing Tools: Mainly used to construct, manage and use data warehouses. They aggregate data from different sources into one comprehensive database. Examples include Amazon Redshift and Google BigQuery.
Data Analysis Tools: These are used to process and analyse large volumes of data, convert them into useful information and insights. Such tools often include data visualization features to display the results in an understandable and meaningful format. Popular data analysis tools include Pandas in Python, or RStudio for R programming.
To illustrate, in structural engineering, AutoCAD is a commonly used data management tool that allows engineers to create, modify, view, or share precise 2D and 3D drawings. It manages the data involving each drawing entity such as lines, polylines, arcs, circles, and text. Tekla Structures, on the other hand, is BrIM (Building Information Modelling) software for structural engineering, which manages the data for the design and construction of structures.
class dataClean: # An illustration of a data cleaning method in Python def __init__(self, dataframe): self.data = dataframe def removeNA(self): self.data = self.data.dropna(inplace=True)You should also ensure that the data is stored in an organised manner using appropriate data structures and schemas, enabling efficient data retrieval when required.
For example, organising a relational database could involve creating various tables for different types of data, with defined relationships between these tables. If data about employees and projects are stored in two different tables, one could establish a relationship using a unique employee id present in both tables which will allow for efficient retrieval of all projects associated with a particular employee.
For example, a Python data cleaning project might involve the following code snippets: # Import required library import pandas as pd # Load the dataset df = pd.read_csv('your_data_file.csv') # Check for missing values missing_values = df.isnull().sum() # Fill missing values with appropriate method df.fillna(method ='bfill', inplace = True)Also, it's gratifying to master a few data management tools and technologies. For instance, for database management, you could learn SQL or NoSQL depending on whether your data is structured or unstructured. Tools like Python's Pandas library or R's dplyr package could assist with data manipulation, while Tableau or PowerBI helps create visually appealing data representations. Additionally, troubleshooting and problem-solving form an important part of enhancing data management skills. Encountering an error and researching to understand it and resolve is a part of the normal workflow. Especially, when working with large datasets which are usually messy and prone to issues, troubleshooting skills come handy. Lastly, patience and perseverance are the bedrock of enhancing any skill, and data management isn't an exception. Given the complexity and scale of data that are encountered in real-life engineering scenarios, managing it is no mean feat. However, equipped with patience, perseverance and the right data management skills, you can make this monumental task a manageable and rewarding endeavour.
Data Integrity: This principle emphasises maintaining the accuracy, consistency, and trustworthiness of data throughout its lifecycle. Ensuring data integrity helps in avoiding data corruption due to hardware errors, bugs, viruses, or human errors.
Data Security: The principle of data security is crucial due to the confidential and sensitive nature of a lot of data. It aims to protect data from unauthorised access, disclosure, modification, or destruction. Data encryption, strong user authentication protocols, and other security measures are used to uphold data security.
Data Accessibility: Accessibility mandates that data should be readily accessible and usable to authorised individuals when they need it. Data management systems should ensure that data is stored in such a way that it can be easily retrieved and used.
Data Quality: Aiming for high-quality data is fundamental to accurate and reliable analysis. Data quality is determined by factors such as accuracy, completeness, consistency, timeliness and relevance. It includes the processes and technologies involved in ensuring the quality of the information.
Data Stewardship: This refers to the administrative activities carried out to manage data assets, including data planning, supervision, and control. It consists of setting internal data standards and policies, data cataloguing, data governance, and other activities that boost the organisation's ability to manage its data.
For instance, consider a civil engineer involved in a large construction project. Here, the data integrity principle can be applied in maintaining the richness of the construction data and ensuring that the construction process aligns with the project's blueprint and design data.
In a software engineering firm that deals with sensitive client and user data, the principle of data security is critical. Implementing advanced encryption techniques and secure coding practices to prevent data breaches exemplify this principle.
For example, the least squares method (\[Y = X\beta + \epsilon\]) where 'X' and 'Y' are known data matrices, '\(\beta\)' is the parameter vector we aim to estimate, and '\(\epsilon\)' is the error term, is applied to maximise data accuracy in energy forecasting models. Here, 'X' could be variables like historical energy demand data, weather conditions, time of the day, etc., while 'Y' would be the predicted energy demand.
To apply data stewardship effectively, firms can use SQL code to set up a metadata management tool: CREATE TABLE MetadataManagement ( DataAssetID int, DataAssetName varchar(255), SourceOfData varchar(255), DataType varchar(255), Description text, PRIMARY KEY (DataAssetID) );By consistently applying these principles, professional engineers can utilise data management to drive efficient processes, improve operational effectiveness, and produce more reliable, high-quality results.
