Database

slide-23
SLIDE 23

Many Questions

slide-24
SLIDE 24

Formats?

slide-25
SLIDE 25

Libraries?

slide-26
SLIDE 26

“Best” approaches?

2 The Solutions

slide-28
SLIDE 28

Bad news

slide-29
SLIDE 29

Far too many

slide-30
SLIDE 30

REST vs SOAP

slide-31
SLIDE 31

XML vs JSON

slide-32
SLIDE 32

Synchronous vs. Asynchronous

slide-37
SLIDE 37

2 parts

slide-38
SLIDE 38

1 PHP server app

slide-39
SLIDE 39

2 iOS client

slide-40
SLIDE 40

Many formats

slide-41
SLIDE 41

XML

slide-42
SLIDE 42

JSON

slide-43
SLIDE 43

(duh)

slide-44
SLIDE 44
  • XML
  • 8 libraries
  • JSON
  • 2 parsers
  • YAML
  • CSV
  • SOAP
  • Property List
  • XML
  • Binary
  • Protocol Buffers
slide-45
SLIDE 45

Extensible

slide-46
SLIDE 46

(add more formats and libraries if you want)

slide-47
SLIDE 47

Variable sized dataset

slide-48
SLIDE 48

(from 1 to 5000 items per call)

slide-49
SLIDE 49

Heterogenous Data Source

slide-50
SLIDE 50

(the same data in different formats)

slide-51
SLIDE 51

XML Libraries

slide-52
SLIDE 52

(lots of them)

4 The Tests

slide-57
SLIDE 57
  • Local
  • Wifi
  • 3G
  • EDGE
  • All Combinations
  • Different dataset

sizes each time

5 Results

slide-60
SLIDE 60

Easier to implement

  • n the iOS side?
slide-61
SLIDE 61
  • 1. JSON + Property Lists + CSV
  • 2. XML (DOM) + Protocol Buffers
  • 3. XML (SAX)
  • 4. SOAP + YAML
slide-62
SLIDE 62

Easier to implement

  • n the PHP side?
slide-63
SLIDE 63
  • 1. JSON + YAML
  • 2. Property List + CSV + XML
  • 3. Protocol Buffers
  • 4. SOAP
slide-64
SLIDE 64

Smaller Payload

slide-65
SLIDE 65
  • 1. CSV + Protocol Buffers + Binary Plist
  • 2. JSON + YAML
  • 3. XML
  • 4. SOAP
slide-66
SLIDE 66

Fastest Deserialization Speed

slide-67
SLIDE 67
  • 1. Property Lists + TBXML
  • 2. SOAP + libxml (DOM) + Google XML
  • 3. JSON
  • 4. YAML + CSV + APXML
slide-68
SLIDE 68

More Portable?

slide-69
SLIDE 69
  • 1. XML + JSON
  • 2. Protocol Buffers + YAML + CSV
  • 3. SOAP
  • 4. Property Lists
slide-70
SLIDE 70

More Readable?

slide-71
SLIDE 71
  • 1. JSON + YAML
  • 2. XML + XML Property Lists
  • 3. Protocol Buffers
  • 4. Binary Property Lists
slide-72
SLIDE 72

Less Memory Consumption?

slide-73
SLIDE 73
  • 1. Binary Property List + Protocol

Buffers

  • 2. CSV + JSON + TBXML
  • 3. XML
  • 4. SOAP + APXML
slide-74
SLIDE 74

Some raw, deeply flawed comparisons?

slide-75
SLIDE 75
  • Binary Plists are 3 to 4 times faster to

deserialize than JSON

  • iPod touch 2nd Gen is ~25% faster than

iPhone 3G

  • iPhone 4 is ~300% faster than iPhone 3G
  • JSON is 45% of its equivalent XML plist
  • Binary plist is 35% of its equivalent XML

plist

slide-76
SLIDE 76

The “Best”?

slide-77
SLIDE 77
  • 1. JSON + Property Lists
  • 2. TBXML + Protocol Buffers
  • 3. Other XML parsers + CSV
  • 4. YAML + SOAP + APXML
