Thinking Outside the Table
Thinking Outside the TableOntotext 1. Relational databases dominated data storage from the 1980s by storing data in tables but struggle with today's exponentially growing and interconnected data.
2. A graph database represents an alternative that allows storing highly connected data through nodes, edges, and properties, avoiding the need to create additional tables to represent relationships.
3. In a graph database, relationships are implicitly part of the data model so there is no need to create junction tables to represent connections like in a relational database.
heapsort
heapsortBhuvneshYadav13 Heap sort is a comparison-based sorting technique that uses a binary heap data structure. It works by first transforming the input array into a max-heap, where the root contains the largest value. It then removes the maximum element from the heap and places it at the end of the sorted array. This process is repeated until the heap is empty. Heap sort has a time complexity of O(n log n) and space complexity of O(1), making it an efficient in-place sorting algorithm.

Integrating Survey123 and R&H Data Using FME
Integrating Survey123 and R&H Data Using FMESafe Software West Virginia Department of Transportation (WVDOT) actively engages in several field data collection initiatives using Collector and Survey 123. A critical component for effective asset management and enhanced analytical capabilities is the integration of Geographic Information System (GIS) data with Linear Referencing System (LRS) data. Currently, RouteID and Measures are not captured in Survey 123. However, we can bridge this gap through FME Flow automation. When a survey is submitted through Survey 123 for ArcGIS Portal (10.8.1), it triggers FME Flow automation. This process uses a customized workbench that interacts with a modified version of Esri's Geometry to Measure API. The result is a JSON response that includes RouteID and Measures, which are then applied to the feature service record.

Built in data structures in python
- 1. www.letthedataconfess.com @letthedataconfess Are you aware of IN -letthedataconfess
- 2. www.letthedataconfess.com The data structure is the way of organising the data in such a way that it can be retrieved quickly. But one data structure is not sufficient to handle all the use case scenarios. That is why we have multiple data structures which can be used for various use cases. What is meant by Data structure ? @letthedataconfess
- 3. www.letthedataconfess.com Why do we need Data structure ? Consider the following scenario, where you want to search for a particular document in file explorer with over 1000 documents stored. One way to do that is by going one by one in a linear way, which is time-consuming. Another way is to jump directly go to that place where it is stored or where the related documents are present. Yes your OS does this, using indexing and hashtables which is a type of data structure. This reduces the time required to search even if there lots of file present. This is why data structures are important. @letthedataconfess
- 4. www.letthedataconfess.com Python data structures 01. List The list is a linear data structure where the data is present sequentially. It's a heterogeneous collection of data which means it can store items of different data types. The list comes with multiple methods to perform operations on them. @letthedataconfess
- 6. www.letthedataconfess.com 02. Tuples A tuple is another data structure that is almost similar to a list except that they are immutable, which means once created then, tuple elements cannot be manipulated means you cannot add or remove elements to it. But you can get the counts and indexes of the elements present. @letthedataconfess
- 8. www.letthedataconfess.com 03. Dictionary Dictionary is a very important data structures that store the data in key-value pairs similar to the hash table. Dictionary is an unordered collection of data that are mutable means, you can add or update the existing values for a given key. @letthedataconfess
- 10. This is another type of data structure on which we can perform set operation like union, intersection, difference, etc. Set doesn't allow duplicate entries. Each value in a set is unique. It's also an unordered collection. www.letthedataconfess.com 04. Sets @letthedataconfess
