     Answered May 16, 2017 · 0 votes

     Storing data in a database is not a major problem. Instead, the problems lies in viewing or manipulating the stored data. For example how frequently one wants to access the data, when do you want to access data, which data you want to access etc. questions to be answered. If you are sure about your data manipulation detail, then you can design tables accordingly and choose appropriate techniques to manipulate the data. You can refer any books on database management systems.

   • How is data stored in a graph database?

     Top Answer

     Answered Feb 14, 2018 · 11 votes

     Your answer is the chapter 6 of the O’Reilly’s Graph Databases book about Graph Database Internals. This chapter describes how Neo4j works internally, including how the Native Graph Storage works.

     Neo4j stores nodes, relationships, labels and properties in separated files.

     Nodes are stored in the file neostore.nodestore.db. This file has a fixed-size by each new created node. For each node added to the database this file is increased by 9 bytes. This way a node with id 100 can be easily found in the 900 byte into the file (id 100 x 9 bytes per node = 900 byte). Node records have pointers to the first node relationship, first node property and for the node labels.

     Relationships are stored in the file neotore.relationshipstore.db. This is a fixed-size file too. Each relationship has pointers to the start and end nodes, relationship type (in the neostore.relationshiptypestore.db file), next and previous relationship records for each of the start and end nodes, and a flag indicating if the relationship is the first in the relationship chain.

     Properties of nodes and relationships are stored in the file neostore.propertystore.db. Each property record has a pointer to the next property and can holds a maximum of 4 properties. Each property has a pointer to the property name (neostore.propertystore.db.index file), the property type. The property value can be an inline value or a pointer to a dynamic file for large strings (neostore.propertystore.db.strings) and arrays (neostore.propertystore.db.arrays file).

     Please check this - http://www.parashift.com/c++-faq/encap-is-for-code-not-people.html

     I think you are misunderstanding what's meant by hiding or encapsulation. It's mean to protect against accidentally modifying a private member - you can only do it by using public functions. It doesn't the member is totally not accessible. Nor is it a way to protect secrets.

   • How is the data in a MongoDB database stored on disk?

     Top Answer

     Answered Nov 08, 2010 · 43 votes

     A given mongo database is broken up into a series of BSON files on disk, with increasing size up to 2GB. BSON is its own format, built specifically for MongoDB.

   • Data Structure Alignment : How data is arranged and accessed in Computer Memory?

     Data structure alignment is the way data is arranged and accessed in computer memory. Data alignment and Data structure padding are two different issues but are related to each other and together known as Data Structure alignment.  Data alignment: Data alignment means putting the data in memory at an address equal to some multiple of the word size. This increases the performance of the system due to the way the CPU handles memory.  Data Structure Padding: Now, to align the data, it may be necessary to insert some extra bytes between the end of the last data structure and the start of the next data structure as the data is placed in memory as multiples of fixed word size. This insertion of extra bytes of memory to align the data is called data structure padding. Consider the structure as shown below:   

     struct { char a; short int b; int c; char d;}

     Now we may think that the processor will allocate memory to this structure as shown below:   

     <img alt="">

     The total memory allocated in this case is 8 bytes. But this never happens as the processor can...
